Leveraging algal-derived biopolymers to alleviate multi-metal phytotoxicity and enhance maize growth in industrially contaminated soils
Environmental Geochemistry and Health (القضية : 6) (الحجم : 48)
Heavy metal contamination of industrial soils severely constrains crop productivity and environmental sustainability. This study evaluated effectiveness of algal-derived biopolymer carrageenan in mitigating multi-metal (Cd, Pb, Zn, Cu) toxicity and improving maize performance in naturally contaminated soils from four industrial zones of Pakistan (Kasur, Faisalabad, Sialkot, and Korangi). A pot experiment with graded carrageenan levels (0–200 mg kg−1) revealed significant improvements in soil physicochemical properties, including increases in pH (≈10–11%) and electrical conductivity (61–94%), alongside enhanced enzymatic activities. Carrageenan application markedly reduced DTPA-extractable metals, with maximum declines of up to 83% (Cd), 70% (Zn), 69% (Pb), and 62% (Cu), thereby limiting their bioavailability. Consequently, metal accumulation in maize roots and shoots decreased substantially, with reductions reaching 90% for Cd and 74% for Pb in shoots. These changes were accompanied by improved plant tolerance indices and significant biomass enhancement. Carrageenan also stimulated antioxidant defense systems, increasing SOD (66–79%), POD (74–150%), and CAT (56–74%) activities, along with glyoxalase function (up to 160%), while elevating non-enzymatic antioxidants such as ascorbate (up to 140%), glutathione (110%), and phytochelatins (179%). Photosynthetic pigments were significantly improved, with total chlorophyll and carotenoids increasing by up to 65% and 168%, respectively. Overall, carrageenan effectively immobilized toxic metals, reduced their translocation, and enhanced physiological and biochemical resilience in maize, demonstrating strong potential as a sustainable amendment for phytoremediation and crop production in metal contaminated soils.

Iron–titanium oxide-engineered biochar mitigates antimony and nickel bioavailability in paddy soil: implications for soil geochemistry, microbial dynamics, and rice grain safety
Environmental Geochemistry and Health (القضية : 5) (الحجم : 48)
Co-contamination of paddy soils with antimony (Sb) and nickel (Ni) poses significant risks to soil quality, crop productivity, and food safety. This study evaluated the effectiveness of iron–titanium oxide-engineered biochar (Fe-Ti-BC) in mitigating Sb and Ni mobility in contaminated paddy soil and examined associated changes in soil carbon dynamics and microbial communities. Compared with the control, Fe-Ti-BC application reduced CaCl2-extractable Sb and DTPA-extractable Ni by 20.31–34.31% and 39.87–79.67%, respectively. Amendment with Fe-Ti-BC and unmodified biochar enhanced the carbon pool management index (CPMI) and labile organic carbon fractions, indicating improved carbon sequestration potential and nutrient cycling capacity. Rice biomass significantly increased following biochar treatments. Iron and titanium concentrations in root Fe plaque were approximately 20-fold and twofold higher, respectively, in Fe-Ti-BC-amended soils than in the control, suggesting enhanced plaque-mediated immobilization of trace elements. Consequently, Sb and Ni concentrations in rice grains decreased by 20.02–78.18% and 60.17–69.79%, respectively. High-throughput sequencing revealed that Fe-Ti-BC reshaped soil bacterial community composition and metabolic activity, promoting keystone taxa including Actinobacteria, Proteobacteria, and Firmicutes. Partial least squares path modeling (PLS-PM) identified CaCl2-extractable Sb, DTPA-extractable Ni, and Fe-Ti plaque formation as key determinants governing trace element accumulation in rice grains. Overall, Fe-Ti-BC effectively stabilized Sb and Ni through coupled geochemical and biological mechanisms, thereby reducing metal transfer to edible tissues while enhancing soil carbon functionality and productivity. These findings highlight the potential of engineered biochar as a sustainable remediation strategy for multi-metal contaminated paddy systems with direct implications for environmental health and food security.

Microbiome–metabolite signaling drives aluminum stress alleviation in soybean under intercropping and selenium nanoparticle application
Plant Signaling & Behavior (القضية : 1) (الحجم : 21)
Aluminum (Al) toxicity and soil-borne pathogens severely constrain legume productivity in acidic soils, yet the signaling mechanisms underlying intercropping-mediated stress alleviation remain insufficiently understood. Here, we investigated whether soybean-sorghum intercropping under Al stress (SSAl), alone or combined with selenium nanoparticles (SSAl + Se), modulates rhizosphere signaling networks and plant defense responses. Integrated 16S rRNA microbiome sequencing and rhizosphere metabolomics were employed to decipher microbe‒metabolite interactions associated with Al detoxification and disease suppression. Compared with monoculture soybean under Al stress (MSAl), SSAl and SSAl + Se significantly reduced Al accumulation (16.9% and 57.4%, respectively) and Fusarium wilt incidence (10.9% and 34.4%, respectively), accompanied by enhanced root growth. These treatments …

Evaluating the Ecological Consequences of Heavy Metals Contamination on Aquatic Ecosystem Functioning in the Tigris River, Iraq
Egyptian Journal of Aquatic Biology and Fisheries (القضية : 2) (الحجم : 30)
This research focuses at how water quality, heavy metal levels, and ecosystem health changed across three different spots along the Tigris River in Iraq during 2024. The goal was to measure heavy metal contamination in the water, river bottom sediments, and areas with different pollution levels. Three locations were chosen: the first as a clean reference point, the second with moderate pollution, and the third heavily polluted. Temperature readings went up from 26.2°C at the cleanest site to 27.4°C and then 28.1°C at the more polluted locations, showing a clear pattern. However, oxygen dissolved in the water dropped from 7.3mg L⁻¹ at the first site to 6.4 and 5.4mg L⁻¹ at the other two. The water's electrical conductivity elevated considerably from 318 to 487 and finally 732 microsiemens per centimeter as pollution increased. Heavy metals became much more concentrated at polluted sites. Iron went from 0.41mg L⁻¹at the clean site up to 1.69 and 3.83 at the others, going beyond safe WHO guidelines. Lead shot up from 0.06 to 0.32 and 1.36 mg L⁻¹, while cadmium climbed from 0.03 to 0.16 and 0.57. Chromium and nickel followed similar upward trends, all crossing safety thresholds. The river's biological health weakened dramatically. Primary productivity fell from 1.78mg O₂ L⁻¹ h⁻¹ to just 0.69mg O2. L⁻¹ hourly (P= 0.006). Dehydrogenase enzyme activity decreased from 0.88 ± 0.05µg TPF g⁻¹ h⁻¹ to 0.31 ± 0.04 µg TPF g⁻¹ h⁻¹, and phosphatase activity dropped from 1.44 to 0.71 µg TPF g⁻¹ h⁻¹. These results show how toxic metals progressively damage river ecosystems, making it clear that better pollution controls and regular monitoring …

Enhancement of maize drought resilience using nano-buckminsterfullerenes and plant growth-promoting rhizobacteria: insights into pigment stability, oxidative stress reduction, and yield
Cereal Research Communications (القضية : 1) (الحجم : 54)
Drought stress severely impairs the biochemical, physiological, and morphological attributes of crop plants, resulting in reduced agricultural productivity and sustainability. The present study evaluated the potential of plant growth-promoting rhizobacteria (PGPR) and nano-buckminsterfullerenes to alleviate drought-induced stress in maize. A greenhouse experiment was conducted in 2024 using a factorial randomized complete block design with five replications. Treatments included three drought stress levels (well-watered, moderate, and severe drought), four foliar application levels of nano-buckminsterfullerenes (0, 5, 25, and 50 mg L⁻¹), and four PGPR treatments (control, Rhizobium, Burkholderia, and combined Rhizobium + Burkholderia). Severe drought stress significantly increased dry matter remobilization from shoots and stems, with stem reserves contributing substantially to grain yield. However, the combined application of PGPR and nano-buckminsterfullerenes under severe drought markedly improved carotenoid content (49.3%), chlorophyll a (31.4%), total chlorophyll (28.7%), leaf area index (40.2%), grain filling duration (19.6%), effective grain filling duration (15.8%), and grain yield (14.3%) compared with untreated controls. Additionally, these treatments reduced cell death rate, hydrogen peroxide (H₂O₂), and malondialdehyde (MDA) levels, while enhancing soluble sugars and protein content. Overall, the results demonstrate that PGPR and nano-buckminsterfullerenes effectively mitigate drought stress and improve maize productivity by enhancing physiological performance and grain filling characteristics.

Impact of MXene Application on the Growth and Pb Accumulation in Chia (Salvia hispanica L.) Seedlings
New Zealand Journal of Crop and Horticultural Science (القضية : 1) (الحجم : 54)
Increasing level of lead (Pb)-polluted agricultural soils jeopardizes chia (Salvia hispanica L.) sustainable cultivation. A pot trial was carried out to explore impact of MXene on the growth and Pb uptake of S. hispanica seedlings, aiming to reduce Pb buildup in S. hispanica. Pb treatment resulted in the reduction of photosynthetic pigment levels and biomass of S. hispanica seedlings, in addition to an elevation in the antioxidant enzyme activities. Under Pb stress, MXene treatment enhanced photosynthetic pigments, biomass, and activity of antioxidant enzyme in S. hispanica seedlings. MXene application reduced root and shoot Pb levelsas well as translocation factor (TF) in S. hispanica seedlings under Pb stress. In contrast to Pb treatment, MXene diminished root Pb concentration by 15%. The TF, carotenoid level, total Chl (a + b), and Chl-a exhibited strong correlation with shoot Pb under Pb stress. Consequently, MXene utilization can enhance growth, impede Pb uptake in roots of S. hispanica seedlings under Pb stress.

Comparative Analysis of Heavy Metal Concentrations in the Blood of Smokers and Non-Smokers in Zakho city, Kurdistan Region of Iraq
Aswan University Journal of Environmental Studies (AUJES) (القضية : 4) (الحجم : 6)
Tobacco smoking is a popular form of recreation globally, and tobacco smoke contains over seven thousand chemical compounds that include toxic heavy metals. The pollutants can result in cardiovascular conditions, cancers, and respiratory illnesses. These metals get accumulated in the consumers' bodies and perform harmful functions such as damaging DNA and triggering inflammation and oxidative stress. This study looks at and compares the amounts of several heavy metals [cadmium (Cd), lead (Pb), nickel (Ni), copper (Cu), and iron (Fe)] in the blood of smokers and non-smokers in Zakho City, Kurdistan Region of Iraq. 50 volunteers (25 smokers and 25 non-smokers) were sampled, and blood samples were examined by Atomic Absorption Spectrophotometry. The results showed that smokers had significantly higher cadmium, lead, and nickel concentrations compared to non-smokers (p < 0.0001). Conversely, copper concentrations were significantly lower among smokers (p < 0.001), while iron concentrations were slightly but significantly higher (p = 0.0007). These findings confirm that smoking is a major source of heavy metal exposure, leading to disruption of trace element homeostasis and with possible health effects. This research emphasizes the need for public health interventions as well as continuous environmental monitoring in the region. Additionally, it offers significant insights to guide local health policies and enhance community awareness.

Scientific Reports (القضية : 1) (الحجم : 15)
Bismuth-based structures are recognized as active photocatalysts against emerging contaminants such as organic dyes. However, the pure form of semiconductors needs modification to improve characteristics such as photo reactivity and catalytic performance. In this context, a novel heterojunction comprising BiOI, amine-functionalized reduced graphene oxide (rGO), and Ag3PO4 was prepared which led to a reduction in energy bandgap and electron–hole recombination rate. Additionally, amine functionalization enhances catalytic performance of ArGO@BiOI photocatalyst against rhodamine B (RhB). The photocatalytic performance of BiOI, ArGO@BiOI, and ArGO@BiOI@Ag3PO4 composites for RhB was observed to be 92.25, 92.57, and 99.40% after 35 min, respectively. Optimizing RhB removal process by response surface methodology (RSM), indicated that the highest removal of ~ 99% was achieved at a …

Ecotoxicology and Environmental Safety (الحجم : 303)
Cadmium (Cd2+) pollution is a persistent problem in the agricultural sector. Plants can be treated with nanoparticles (NP) to reduce heavy metal stress. MXene nanoparticles (MX-NPs) were tested for wheat Cd stress relief. Comparative confocal microscopy was used to examine the morphology, physiology, yield, biochemistry, antioxidant enzyme activity, and cell viability of the wheat plants. Cd-stressed plants exhibited a decline in morphological parameters and yield attributes, including leaf area (-49 %), root length (-35 %), shoot length (-18 %), seed weight (-37 %), seeds per plant (-69 %), root and shoot fresh weight (-55 % and −64 %), carotenoid levels (-40 %), total chlorophyll (-13 %), total soluble sugar (-29 %), total soluble protein (-39 %), antioxidant enzymatic activities (APX, CAT, and SOD by −16 %, −5 %, and −14 %, respectively), and nitrate reductase activity (-65 %) compared to the control group. Stress markers, including MDA (+270 %) and proline (+201 %), increased in plants exposed to Cd. Levels of total flavonoids (+481 %) and phenols (+92 %) were greater in the Cd-treated groups. Foliar application of MX-NPs (1000 ppm) significantly alleviated Cd-induced stress, as demonstrated by increases in shoot length and root length (+41 % and +39 %, respectively), seed weight (+69 %), seeds per plant (+99 %), carotenoid concentration (+30 %), chlorophyll content (+39 %), nitrate reductase activity (+60 %), and total soluble protein (+19 %) compared with the control group. The supplementation of 1000 ppm-MX-NPs with Cd (250 μM) in exposed plants led to an enhancement in antioxidant enzymes, with APX, CAT, and SOD increasing by 76 %, 81 %, and 84 %, respectively. Confocal microscopy revealed that MX-NPs increased cell viability following Cd exposure. In conclusion, MX-NPs foliar spray effectively reduced Cd-induced stress in wheat, promoting sustainable agriculture under 500 μM Cd stress.

Impacts of Noise Pollution on Physiological Parameters of High School Students in Zakho, Kurdistan Region, Iraq
Aswan University Journal of Environmental Studies (القضية : 3) (الحجم : 6)
Noise pollution is becoming a serious environmental issue, especially in schools where students are regularly exposed to high noise levels. This study investigated the impact of noise affects body composition and physiological health in high school students at Sara-rem High School in Zakho, Iraq. Fifty 11th-grade students (ages 16–17) were divided into three groups: a control group in a quiet garden, a pre-exam group, and a post-exam group. Researchers measured noise levels with a sound level meter. They tracked physiological markers like oxygen saturation (SpO₂), body water content (BWC), body fat percentage (BF%), body muscle mass (BMC), body mass index (BMI), calorie intake, and blood pressure using standard medical devices. The findings showed big differences in noise exposure—the pre-exam group faced the loudest conditions (average 95.8 dB, peaking at 97.8 dB), while the control group had lower levels (around 85 dB). Male students had a noticeable drop in SpO₂ after exams (88.83% ± 3.24, p = 0.0504) and ate more calories (pre-exam: 2413 ± 88.12; post-exam: 2427 ± 92.44, p = 0.01). Female students saw increases in BWC (59.86% ± 4.7, p = 0.04) and BMC (77.29% ± 1.36, p = 0.043). Blood pressure also rose during exams for both genders (males: 133 ± 3.2 mmHg, p = 0.0109; females: 129.1 ± 3.41 mmHg, p = 0.008). These results suggest that noise pollution takes a real toll on students’ health, particularly during stressful periods like exams. Schools should consider ways to reduce noise and protect students from these harmful effects.

Journal of Scientific Development for Studies and Research (JSD) (القضية : 23) (الحجم : 6)
Soil plays a vital role in food production, making sustainable soil management essential for environmental and agricultural health. This study assesses heavy metal contamination and physico-chemical properties of roadside soils along the Duhok to Zakho highway in the Kurdistan Region, Iraq. Increased vehicular traffic on public roads has notably affected soil quality. Understanding the impact of highways on soil properties is critical for achieving sustainability. In this investigation, 20 soil samples were collected from both the left and right sides of the highway at distances of 5 m and 15 m from the road edge, at a soil depth of 0–15 cm. The samples were analyzed for physical properties (soil texture, moisture content, organic matter, field capacity) and chemical properties (pH, electrical conductivity, organic carbon, nitrogen, C:N ratio), along with concentrations of the heavy metal lead (Pb). The analysis showed that soil texture varied among sites—classified as clay, sandy clay loam, loam, or sandy loam—indicating general suitability for arable crops. Results revealed pH ranged from 4.40 to 6.60, EC from 0.72 to 1.02 dS/m, organic matter from 0.13% to 6.12%, nitrogen from 0.08% to 0.84%, moisture content from 2.90% to 15.00%, field capacity from 27.51% to 37.93%, and organic carbon from 0.29% to 3.68%. Lead concentrations ranged from 2.00 to 3.11 mg/kg and exceeded WHO permissible limits. Farmers are encouraged to use soil health cards and apply sustainable management practices.

Green Synthesis of AgNPs for Groundwater Remediation: Characterization and Heavy Metal Removal Performance
Innovative Environmental Engineering Solutions (القضية : 1) (الحجم : 1)
This study addresses the issue of toxic heavy metal contamination of groundwater and proposes an innovative and sustainable remediation strategy using green synthesized silver nanoparticles (AgNPs). While previous studies have demonstrated the potential of AgNPs in water purification, this study is unique in using a plant-mediated synthesis route using Vernonia anthelmintica (L.) and evaluating its effectiveness. This column-based method offers valuable insights into the practical application and scale-up of AgNPs, especially in resource-limited settings. Comprehensive analysis of groundwater samples discovered that although physicochemical parameters such as pH, electrical conductivity (EC), and dissolved solids (DS) were within acceptable limits, while turbidity, arsenic (As), cadmium (Cd), lead (Pb), nickel (Ni), and zinc (Zn) exceeded the World Health Organization (WHO) limits. However, these values were reported in the limits prescribed by Pakistan National Environmental Quality Standards (Pak-NEQS). The eco-friendly AgNPs displayed significant removal capacities, especially for Zn, Cd, and As. This performance is due to their large specific surface area and the presence of active functional groups, as confirmed by Fourier transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD) analysis. The nanoparticles showed antibacterial qualities in addition to their potent adsorptive activity, which increased their suitability for water purification. This study offers a viable and scalable way to reduce groundwater contamination by combining green nanotechnology with economical, ecologically f​r​.....

Assessing Health Risk Mitigation Efficiency of the Halabja Water Treatment Plant in Drinking Water Purification
Passer Journal of Basic and Applied Sciences (القضية : 2) (الحجم : 7)
Water quality management represents a paramount public health issue, especially within areas where surface water resources are particularly susceptible to contamination. This investigation evaluates the efficacy of health risk mitigation provided by the Halabja Water Treatment Plant (HWTP) . The facility processes water sourced from Sirwan Lake, employing methodologies such as sedimentation, filtration, and disinfection. The primary aim was to ascertain the removal efficiency of trace elements (e.g., As, Pb, Cd, and Cr) throughout various treatment phases, while also examining the potential health hazards linked to the consumption of tap water. Water samples were systematically collected on a monthly basis over a two-year period (2022–2023) at three distinct phases: raw water, treated water, and tap water. Analytical techniques encompassed trace element quantification alongside health risk evaluation utilizing hazard quotient indices (HQ). The results indicated a significant reduction in turbidity (from 59 NTU in raw water to between 0.1 and 5 NTU in treated water) as well as in heavy metal concentrations. For instance, cadmium levels diminished from 0.48 µg/L in raw water to 0.018 µg/L in treated water, while arsenic concentrations were reduced from 2.951 µg/L to 2.503 µg/L. Nonetheless, occasional exceedances of WHO standards were detected in tap water, with lead concentrations peaking at 9.4 µg/L in November, suggesting potential recontamination during the distribution process. Hazard indices remained below the critical threshold of 1 for the majority of metals, signifying manageable health risks. The highest hazard index for pre-treated water was recorded at 0.61 (in September), which subsequently declined to 0.15 following treatment. These findings underscore the success of HWTP in diminishing contaminants. This study contributes to the optimization of water treatment methodologies and emphasizes the critical importance of ongoing monitoring to ensure the provision of safe drinking water.

Materials Engineering and Technologies (القضية : 1) (الحجم : 1)
The biosynthesis of silver nanoparticles (AgNPs) using biological methods has gained increasing attention due to their broad range of applications. In this study, AgNPs were synthesized via a simple and eco-friendly approach using Vernonia anthelmintica stem and leaf extract as both a reducing and stabilizing agent. The synthesized nanoparticles were characterized through UV-Visible spectroscopy, Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), and X-ray diffraction (XRD). UV-Vis analysis revealed a distinct surface plasmon resonance (SPR) peak at 413 nm, confirming the formation of AgNPs. XRD results indicated a crystalline structure with an average crystallite size of approximately 49 nm, while SEM analysis revealed an average particle size of around 21 nm, suggesting polydispersity. EDX spectra confirmed the presence of elemental silver, and FTIR analysis identified functional groups such as alkenes, dicarboxylic amino acids, and sulfonyl chlorides, indicating their role in the reduction and stabilization of the nanoparticles. The synthesized AgNPs exhibited notable antibacterial activity against Staphylococcus aureus (Gram-positive) and Citrobacter (Gram-negative), with inhibition zones of 20 mm and 18 mm, respectively. In contrast, the plant extract alone showed no antibacterial effect. The AgNPs also demonstrated antifungal activity against Echromonium, Penicillium, and Pythium, whereas the crude extract was inactive against these fungi. Additionally, antioxidant activity, assessed using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, showed …

Associations between essential trace elements and sleep quality in Iranian adults based on the Pittsburgh Sleep Quality Index
Scientific Reports (القضية : 15) (الحجم : 15)
Sleep is a fundamental physiological process essential for maintaining both physical and mental well-being. Various biological, environmental, and nutritional factors influence sleep quality, with recent studies focusing on the role of trace elements. Therefore, this study aims to investigate the individual and combined effects of serum levels of essential trace elements—specifically magnesium (Mg), calcium (Ca), iron (Fe), manganese (Mn), cobalt (Co), copper (Cu), zinc (Zn), and selenium (Se)—on sleep quality among Iranian adults, utilizing the Pittsburgh Sleep Quality Index (PSQI). This cross-sectional study involved 99 individuals with sleep disorders who were referred to Farabi Hospital between October 2024 and February 2025. Sleep quality among participants was assessed using the PSQI, while serum levels of essential elements were analyzed through inductively coupled plasma mass spectrometry (ICP-MS). The study’s findings revealed a negative correlation between Fe concentration and total PSQI scores (Beta = − 0.02, 95% CI − 0.03 to 0.00, P = 0.03). Higher levels of Fe were associated with a reduced risk of poor subjective sleep quality (OR 0.984, 95% CI 0.971 to 0.995, P = 0.009) and shorter sleep latency (OR 0.986, 95% CI 0.972–0.990, P = 0.03). Additionally, an increase in Fe concentration correlated with improved habitual sleep efficiency (OR 0.984, 95% CI 0.968 to 0.997, P = 0.02). Using the quantile g-computation model, Fe was identified as the most significant factor influencing the overall PSQI score. Furthermore, the generalized additive model indicated notable non-linear relationships between Co and the global PSQI score (P = 0.02), as well as between Zn and the global PSQI score (P = 0.034). In conclusion, the results highlights that individuals with low serum Fe levels face a considerably higher risk of poor sleep quality. Additionally, Co concentration was found to exert a significant negative effect on the global PSQI score, further pointing to the importance of trace elements in sleep health.

Future of Three Endemic Woody Species of Colutea (Fabaceae) in a Changing Climate in Iran
Ecology and Evolution (القضية : 5) (الحجم : 15)
Woody plants offer valuable services to ecosystems, including providing useful products, stabilizing ecosystems, and mitigating climate and pollution effects. However, they face significant abiotic and biotic stresses, with climate change being the most critical challenge. It is essential to understand that reducing populations of woody species, particularly those found only in a specific area, can have severe and irreversible effects on the entire ecosystem. Therefore, exploring the potential influence of climate change on the distribution of endemic woody species is an appealing subject for conservation researchers. This study investigates how climate change affects the distribution of three endemic species of woody plants in the genus Colutea in Iran. The MaxEnt model was used to analyze the data, and the results showed that the model was effective for predicting the impact of climate change on the plants (AUC ≥ 0.9). The distribution of C. persica was significantly affected by solar radiation, Precipitation of Wettest Month, sand, and silt content. C. porphyrogamma's distribution was impacted by Mean Temperature of Coldest Quarter, Precipitation of Driest Month, and Cation Exchange Capacity, while C. triphylla was most affected by Precipitation Seasonality, Precipitation of Driest Quarter, and Isothermality. According to the findings, the distribution of these species is expected to decrease in the 2050s and 2070s due to climate change, based on the RCP4.5 and RCP8.5 climate scenarios. These findings can be useful for developing strategies to manage the impacts of climate change on these species.

Water, Air, & Soil Pollution (القضية : 8) (الحجم : 236)
The remediation of contaminated soils with heavy metals is a critical environmental policy in both developing and industrialized countries. The various adsorbents utilization is an effective method for the immobilization of toxic metals in contaminated soils. The present research sought to evaluate lead (Pb) immobilization in contaminated calcareous soil impacted by the application of different amendments such as Acacia-wood biochar MXenes, and nZVI and their interaction during maize growth. The study employed three amendments, biochar MXenes, and nZVI at three concentrations (0, 2.5, and 5%) and various levels of Pb pollution (0, 50, and 100 mg/kg soil). An incubation time of 16 weeks was designated for homogenization of supplements in soil, and maize cultivated following standard procedures. After incubation, various fractions of Pb, such as residual, organic matter-bound, carbonate-bound, exchangeable, and manganese and iron-bound, were determined. Additionally, Pb was assessed using EDTA and DTPA techniques and 1000-grain weight of maize was recorded. The findings indicated that maximum concentration of Pb associated with organic matter was achieved in the 5% Acacia-wood biochar application, reaching 20 mg/kg. Maximum and minimum concentration of Pb extracted was DTPA were recorded in the control sample (95 mg/kg) and 5% biochar treatment (65 mg/kg). Findings indicated that enhancing quantities of biochar and MXenes supplements enhanced weight of 1000 grains of maize across all treatments. Results indicate that biochar and MXenes addition decreased level of Pb extracted using EDTA (129 mg/kg) and DTPA (79 mg/kg). Findings indicated that biochar and MXenes application decreased active Pb and Pb mobility in soil by enhancing carbonate and organic fractions. The biochar and MXenes addition in remediation of soil can improve their efficacy in decreasing the level and active Pb mobility. Biochar offers stable C matrix for more Pb immobilization, whereas MXenes enhance adsorption potential and facilitate ion-exchange ability.

Serum levels of trace elements in diabetic pregnant women and their relationship with growth indicators in newborns
Scientific Reports (القضية : 15) (الحجم : 15)
Intrauterine life is a critical and sensitive period during which the fetus is particularly vulnerable to external influences such as trace elements. Therefore, this research focuses on a group of diabetic and non-diabetic mothers to clarify the impacts of maternal trace element status on neonatal outcomes. This case–control study involved 111 pregnant women—57 with diabetes and 54 without—as well as their infants. Maternal blood samples were collected before delivery, and the serum levels of lead (Pb), cadmium (Cd), mercury (Hg), selenium (Se), zinc (Zn), chromium (Cr), nickel (Ni), copper (Cu), iron (Fe), and arsenic (As) were analyzed using inductively coupled plasma mass spectrometry (ICP-MS). Demographic data were recorded using a checklist, and after birth, the infants’ height, weight, and head circumference were measured. There were no statistically significant differences in the trace element levels between the two groups. In the non-diabetic group, only the correlation between Cu concentration and head circumference was significant (r = − 0.33, P = 0.015). In the diabetic group, there were significant inverse relationships between the concentrations of Cu and Fe with growth parameters, specifically for Fe and birth weight (r = − 0.265, P = 0.047), for Fe and head circumference (r = − 0.314, P = 0.017), for Cu and birth weight (r = − 0.374, P = 0.004), and for Cu and head circumference (r = − 0.345, P = 0.009). Additionally, a positive and significant relationship was found between Cr levels and the weight, height, and head circumference of the infants. Based on the results of multivariate regression analysis, among diabetic mothers, elevated Cu levels negatively impacted both the weight and head circumference of the infants and Cr concentration positively correlated with birth length, while exposure to cigarette smoke adversely affected the infants’ weight. These findings highlight the importance of maternal health, particularly the status of trace elements and lifestyle factors such as smoking, in influencing neonatal outcomes.

Adsorption-desorption of doxycycline using pyrophosphoric acid-modified biochar derived from sesame stalk
Global NEST Journal (القضية : 6) (الحجم : 27)
The knowledge of the adsorption-desorption behavior of doxycycline on pyrophosphoric acid modified biochar derived from sesame is limited. In this study, we examined the doxycycline sorption on pyrophosphoric acid modified-sesame stalk biochar. The isotherm and kinetic sorption data showed pyrophosphoric acid treatment enhanced the sorption of doxycycline on both modified and un-modified biochar; and showed the chemisorption including EDA interaction(π-π electron-donor-acceptor) interaction, pore filling and H-bonding might be the primary mechanism. The maximum adsorption capacities for unmodified biochar were (87.6 mg g−1), and 153.9mg g−1 for modified biochar (153.9mg g−1), it was many times higher than pristine biochar. More than 90% of the adsorption capacity was retained after three successive adsorption-desorption cycles. Besides, the strong electrostatic attraction between biochars and doxycycline might largely explain the improved sorption capacity of doxycycline along with increasing pH from 5 to 9. The main responsible mechanisms for the sorption of doxycycline included surface complexation, H-bonding, π-π electron-donor-acceptor (EDA) interactions, pore-filling effects. The results of the current study display that pyrophosphoric acid-modified biochar has potential applications as an efficient, recyclable adsorbent for the removal of antibiotics from wastewater for low-cost remediation.

Unused, unwanted, and expired household medications can accumulate and be improperly disposed of, posing a major national and international public health and environmental concern. This problem is primarily caused by a lack of awareness and understanding of appropriate medicine disposal techniques. This study aimed to assess the knowledge, attitudes, and practices regarding the disposal of unused, unwanted, or expired household medicines among the general public in Duhok city, in the Kurdistan Region of Iraq. Between March 6 and June 6, 2023, 250 participants were interviewed in person using a pre-validated structured questionnaire for this cross-sectional study. The accuracy of the returned questionnaires was verified multiple times. Descriptive statistics were calculated for the sample population's characteristics, and the findings were presented in tables as percentages. Out of the 250 respondents included in the study, 115 (46%) were females, and 165 (66%) were married. A total of 205 (82%) of the respondents had formal education. The most commonly used disposal practice for unused medicines was throwing them in household garbage, as reported by 137 (54.8%). Interestingly, 127 (61.95%) of the participants who disposed of medicines in the garbage had formal education. About 68 (27.2%) of the participants kept unused or unwanted medicines at home for future use or until expiration, followed by giving them to friends and relatives (23, or 18.07%), while a few (12, or 9.27%) burned medicines at home. Significantly, 206 (82.4%) of the respondents did not check the expiry date before taking medicine. A majority of respondents, 155 (62%), held the government responsible for creating awareness about proper medicine disposal. Almost all participants (220, or 88%) felt that improper disposal of unused and expired medicines can affect the environment and health. This study revealed that the most common ways to dispose of unused, unwanted, and expired medication were tossing them in the trash and storing them for later use.

Application of Mont Carlo Simulation and Artificial Neural Network Model to Probabilistic Health Risk Assessment in Fluoride-Endemic Areas
Heliyon (القضية : 24) (الحجم : 10)
Groundwater contamination with fluoride is a considerable public health concern that affects millions of people worldwide. The rapid growth of urbanization has led to increase in groundwater contamination. The health risk assessment focuses on both acute and chronic health consequences as it investigates the extent and effects of fluoride exposure through contaminated groundwater. Fluoride exposure, especially in endemic locations, has serious health consequences, including dental and skeletal fluorosis. An accurate assessment of these hazards is essential for public health planning and mitigation actions. The present study uses Monte Carlo Simulation (MCS) and an Artificial Neural Network (ANN) model to perform a Probabilistic Health Risk Assessment on populations in fluoride-endemic areas. Analysis of the results of the study reveals that the concentration of fluoride ranged from 0.58 to 3.80 mg/L with an average of 2.30 mg/L across the Kasganj district, which was higher than permissible limits given by BIS and WHO. The highest value of hazard quotient of 3.29 for Children is found to be in the Durga Colony area, while the lowest value of the hazard quotient of 0.31 for adults is found to be in the Nadrai Gate area. The assessment of health risks revealed a high probability of non-carcinogenic disease from the consumption of groundwater containing fluoride. The ANN model has the R2 value of 0.9989 in training and 0.9870 in testing while RMSE value in training and testing was 0.02230 and 0.0267. The findings suggest that before being used, the groundwater in Kasganj, Uttar Pradesh, India, needs to be treated and made drinkable. The results emphasize the critical need for ongoing monitoring, public education initiatives, and implementing feasible mitigating techniques to lower fluoride exposure. The findings show that this hybrid model is excellent at addressing the numerous uncertainties associated with fluoride use, hence improving the reliability of health risk estimates in fluoride-endemic locations. The results offer vital information to help policymakers and local health officials create focused measures to safeguard public health in Kasganj.

Acid red 14 (AR14) is a widely used azo dye that belongs to a major family of commercial dyes employed extensively in the textile industry. The present study aimed to investigate the photocatalytic discoloration of AR14 using a visible-light-responsive catalyst. The composite catalyst was synthesized by integrating thermally modified MIL-101 (M-MIL) integrated into bismuth oxide. Thermal modification of MIL-101 produced octahedral α-Fe2O3 particles with a size of 1–2 μm, which were incorporated into bismuth oxyiodide (BiOI) featuring a nanosheet structure. BiOI@M-MIL composite exhibited an enhanced photocatalytic activity. The bandgap energy, Eg, of BiOI was reduced from 1.95 eV to 1.73 eV in the composite. Photocatalytic reactions were performed under visible-light irradiation using a 5 W cold LED lamp. The AR14 discoloration tests demonstrated that BiOI@M-MIL was 1.81-fold more efficient compared to pristine BiOI. Key parameters affecting AR14 discoloration —such as catalyst dosage, pH, dye concentration, and contact time, were investigated. The composite achieved almost a complete dye removal efficiency of 94.26% under experimental conditions. Radical trapping tests highlighted the crucial role of superoxide radicals, in the dye discoloration process. BiOI@M-MIL takes advantage of simultaneous adsorption and photocatalysis with the highest adsorption capacity of 45.32 mg g−1 and 32.2 mg g−1, based on Sips and Langmuir models, respectively. The catalyst also showed good reusability and ~14% loss in removal efficiency after five consecutive cycles. In conclusion, the BiOI@M-MIL composite demonstrates excellent photocatalytic performance, combining low energy consumption with material stability, making it a promising candidate for AR14 discoloration.

Minerals (القضية : 10) (الحجم : 14)
Mineral prospectivity mapping (MPM) is crucial for efficient mineral exploration, where prospective zones are identified in a cost-effective manner. This study focuses on generating prospectivity maps for hydrothermal polymetallic mineralization in the Feizabad area, in northeastern Iran, using unsupervised anomaly detection methods, i.e., isolation forest (IForest) and deep isolation forest (DIF) algorithms. As mineralization events are rare and complex, traditional approaches continue to encounter difficulties, despite advances in MPM. In this respect, unsupervised anomaly detection algorithms, which do not rely on ground truth samples, offer a suitable solution. Here, we compile geospatial datasets on the Feizabad area, which is known for its polymetallic mineralization showings. Fourteen evidence layers were created, based on the geology and mineralization characteristics of the area. Both the IForest and DIF algorithms were employed to identify areas with high mineralization potential. The DIF, which uses neural networks to handle non-linear relationships in high-dimensional data, outperformed the traditional decision tree-based IForest algorithm. The results, evaluated through a success rate curve, demonstrated that the DIF provided more accurate prospectivity maps, effectively capturing complex, non-linear relationships. This highlights the DIF algorithm’s suitability for MPM, offering significant advantages over the IForest algorithm. The present study concludes that the DIF algorithm, and similar unsupervised anomaly detection algorithms, are highly effective for MPM, making them valuable tools for both brownfield and greenfield exploration.

Toxic Gases and Human Health: A Comprehensive Review of Sources, Health Effects, and Prevention Strategies
Journal of Materials Science Research and Reviews (القضية : 4) (الحجم : 7)
The likelihood of toxic gases occurring within a specific timeframe and location determines the likelihood of the event. The aim of this study is to review the literature on the effects of hazardous gases on human health. Hazardous gas releases can tragically occur as a result of industrial accidents, natural disasters, or terrorist attacks in inhabited regions. The literature introduces several modeling methods and approaches to both prevent and assess the effects of these disasters. These tools are invaluable resources for risk managers evaluating the risks associated with vulnerable areas. Although risk assessments for toxic gas dispersion have significantly improved, they often do not account for people's movements and behavior during emergencies. To enhance the accuracy of risk assessments for disasters involving toxic gases, this study proposes a method that considers both gas dispersion modeling and evacuation dynamics. Identifying effective methods for reducing toxic gas pollution and its adverse effects on the environment and human health is crucial. Toxic gases can harm nearly every organ and system in the body. Additionally, we discuss various corrective measures to mitigate their toxicity.

Global warming: Causes, impacts and urgent strategies for a sustainable future: A review
GSC Advanced Research and Reviews (القضية : 3) (الحجم : 20)
Global warming is defined as a rise in Earth's average temperature. As the Earth gets warmer, disasters such as droughts, hurricanes, and floods are becoming increasingly common. Most scientists, engineers, and activists express deep concern about changes in the planet's overall climate. The average air temperature above the surface of the Earth has risen by just below 1 degree Celsius, or 1.3 degrees Fahrenheit, over the past 100 years. Deforestation exacerbates the severity of global warming. The ocean, which holds about 50 times more carbon than the atmosphere, is an enormous carbon sink. However, the seas are no longer able to store carbon as effectively as they have in the past. Burning fossil fuels such as natural gas, oil, coal, and gasoline increases atmospheric carbon dioxide levels, and carbon dioxide is a major contributor to the greenhouse effect and global warming. Climate change will increase the number of people who suffer from heatwaves, floods, hurricanes, and droughts, leading to higher rates of death, illness, and injury. The threat of global warming continues to cause severe damage to the Earth's environment. Many people still do not fully understand the implications of global warming or consider it a significant problem for the future. However, global warming is already happening, and some of its devastating consequences are already being felt. It significantly impacts biodiversity and disrupts ecological balance. Due to the dangerous effects of global warming, many strategies need to be established. The report discusses global warming, outlines its causes and risks, and proposes solutions to this urgent issue. Above all, it is crucial to seriously consider alternative energy sources (biomass, wind, hydro, geothermal, and solar). One of the key strategies to counter the ever-increasing global warming is the identification and use of renewable energy sources.

Salinity stress in plants: Growth, photosynthesis and adaptation review
GSC Advanced Research and Reviews (القضية : 2) (الحجم : 20)
Salinity is a significant abiotic stress that decreases plant growth and productivity in many parts of the world due to increased use of poor-quality water for irrigation and soil salinization. Salinity stress negatively impacts agricultural yields globally, affecting production for both subsistence and financial gain. Salt stress affects every aspect of crop growth, inhibiting plant growth and reducing the fresh and dry weight of roots, stems, and leaves. It also decreases leaf expansion and alters leaf morphology. Additionally, salt stress represses photosynthesis and disrupts plant ion homeostasis, leading to metabolic imbalances and oxidative stress. The adaptation or resistance of plants to salinity stress involves complex physiological features, metabolic pathways, and networks of molecules or genes. To develop salt-tolerant plant varieties for salt-affected areas, a comprehensive understanding of plant responses to salinity stress at various levels and an integrated approach combining molecular, physiological, and biochemical techniques are necessary. Recent research has identified many adaptive responses to salinity stress at genetic, cellular, metabolic, and physiological levels. However, the mechanisms underlying salinity tolerance are still not fully understood. In this review, we investigate the damage caused to plants by environmental salt stress and explore how plants tolerate this stress at the molecular level.

An investigation was carried out to explore the effect of dietary protein on growth, feed utilization efficiency, condition factor, and length-weight relationships in common carp (Cyprinus Carpio). 3600 C. carpio were sourced from a Mosul fish hatchery and transported to a private farm in Khanki township, where they were divided into four groups of 900 each. Following a day of acclimation, the fish were placed in 4× 4× 3m water culture ponds and fed diets with different protein concentrations (T1: 30%, T2: 28%, T3: 30%, and T4: 35%) for 90 days. From each group, twenty fish were selected for data collection. Results indicated that the growth parameters, such as daily weight gain, total weight gain, weight gain rate, relative growth rate, metabolic growth rate, and specific growth rate, were higher in fish fed a 28% protein diet (T1) compared to other protein concentrations (T1: 30%, T3: 26%, and T4: 35%). Nutrient utilization parameters, including daily feed consumption, total feed consumption, daily protein consumption, and total protein consumption, were elevated in fish fed with 35% protein (T3). T2 exhibited a significantly higher feed efficiency ratio and protein productive value compared to other diets. The feed conversion ratio was markedly decreased in fish fed a 28% protein diet (T2). Fulton condition factor and modified condition factor were significantly elevated (P< 0.05) with a 28% protein diet (T2), while the relative condition factor decreased. The length- weight relationships indicated isometric growth in T3 (26, 35%), allometric positive growth in T2 (28%), and negative growth in T1 (30%). In conclusion, the study highlighted the superior growth performance and nutrient utilization efficiency in common carp when fed a 28% protein diet (T2).

GSC Advanced Research and Reviews (القضية : 17) (الحجم : 4)
One possible source of fresh water is rainfall. Nonetheless, the natural composition of rainwater may change due to air pollution in any areas. The Kwashe and Gara in the Duhok Governorate, in the Kurdistan region of Iraq, was selected as the study areas. Heavy metals concentration of rainwater was investigated. Seven samples were taken during rainy January and February 2023 for this investigation, and a statistical analysis was carried out to identify the factors influencing the quality of the rainwater. The concentrations of heavy metals (Zn, Pb, Ni, Cr, Cd, Mn, Cu, Fe, and Co) were measured with an atomic absorption spectrophotometer (AAS) and compared to WHO standards. The purpose of the study was to compare the heavy metal content of study area rainwater to WHO standards in order to determine the effects of these metals on community members' individual health as well as the environment. The heavy metal concentrations dropped in the following order:(Zn, Pb, Ni, Cr, Cd, Mn, Cu, Fe, and Co in Kwashe and Zn> Ni> Cu> Pb> Cr> Fe> Mn> Cd> Co in Gara). The following heavy metals are within the WHO's permissible limit: Fe, Cu, Zn, Mn, and Co; the others exceeded it. The results indicate that the rainwater sources in the study areas are unsafe and unfit for human consumption. Because of this, rainwater from research areas needs to be treated before drinking in order to prevent Pb, Cd, Ni, and Cr-related health problems.

Statistical Analysis of Rainfall Variations in Duhok City and Semel District, Kurdistan Region of Iraq
International Journal of Research in Environmental Science (IJRES) (القضية : 3) (الحجم : 9)
Data on rainfall are a crucial meteorological input for planning and management studies of water resources as well as agricultural modeling systems. Environmental conditions, particularly rainfall and water availability, have a significant impact on crop choice and agricultural production output. The influence of climate variables, such as rainfall, is so strong in Kurdistan that overall agricultural productions are now in danger. In this study, rainfall data of 48 years (1974 to 2022) were used to determine variation in rainfall in Duhok city and Semel district in Kurdistan Region of Iraq. Annually rainfall amount data of forty-eight years (1974- 2022) was obtained from the Directorate of Agriculture (Duhok and Semele). An analysis of rainfall variations in the Duhok city and Semel district shows that 1974-1975 (158 and135mm, respectively) recorded the least average rainfall across the study area and over the years while the highest average rainfall was recorded in 2018-2019 (1199.3, 991mm, respectively). Although in 2007-2008 recorded the second least average rainfall (216 and 141.6mm, respectively), and the second highest rainfall in Semel district is in 1988- 1989, but in Duhok city is in (1987-1988) over the study period. Non availability of rainfall data for 1990 year in Semel was a major limitation to this study; because in this year the uprising began and people migrated abroad. Similarly, trend analysis shows that there are increasing (+ve), decreasing (-ve) and somewhat constant trends for the different years. Statistical measures (mean, median, maximum, minimum, standard deviation, variance, skewness, kurtosis and coefficient of variation, etc.) have been used. The analysis of rainfall variations from the study area shows that Duhok city and Semel district recorded the average annual rainfall amount of (533.7 and 437.18mm) over the years. The results indicated that for the annual rainfall, median, maximum, minimum, standard deviation, variance, skewness, kurtosis, coefficient of variation and correlation coefficients was found as (540.8, 463.7mm), (1199.3, 991mm), (158, 135mm), (207.1, 169.95mm), (42871.4, 28884.49mm), (0.6596, 0.419mm), (1.009, 1.282mm), (38.79, 38.88%), and (0.715) respectively during the study period. A reliable indicator of climate trends can be found in the temporal fluctuation of rainfall. In addition, these rainfall variations are used in many engineering aspects, including design of massive civil engineering structures like dams, design of water supply networks, it greatly contributes in water resources system planning and management, etc. Furthermore, the rainfall variations are not only important in engineering aspects but also heavily in agriculture. Therefore, this research paper presents an analysis of temporal variation of rainfall in Semel, Kurdistan Region. Initial results show some interesting trends in rainfall over a period of 48 years.

Environmental Science Archives (القضية : 2) (الحجم : 2)
Even though rainfall is thought of as a source that is free from contamination, human activities, especially those in the industrial and agricultural sectors, contaminate this clean kind of water. This study was conducted in two regions (Kwashe industrial area and Gara natural area) for the evaluation of rain water quality and indirectly the comparison between the evaluation of air pollution load created in both areas in Duhok governorate, the Kurdistan Region of Iraq. For this investigation, seven samples of each area were collected in the months of January and February 2023 during rainfall and they were compared. After data collection, a statistical analysis was carried out to determine the variables that affected rainwater quality. According to the current study, the first rain's water quality was significantly worse than the second rain's due to pollution. It was determined that there was a substantial difference between the first and second rain, favoring increased air pollution in the industrial region. The variation in pollutant concentrations of rainfall provides a general idea of the area's air pollution load. The outcomes of the quality evaluation program largely agreed with those found by a number of other researchers. The findings of the rainwater quality test show that pH values were lower in the Kwashe area and that some values throughout the research period exceeded the WHO-recommended limits for transportable. The results of the quality analyses indicate that it is not recommended to drink rainwater that has not been treated when it falls directly on an industrial area since it poses a health risk.

Community Perception of Odour Pollution and it is Impact on Surrounding Area: A Case Study in Kwashe Industrial Area, Kurdistan Region-Iraq
International Journal of Advances in Engineering and Management (IJAEM) (القضية : 3) (الحجم : 5)
Background: Odour is an important factor in assessing the quality of life in any area and cities. Odour pollution from industrial area is one of the contaminants that affects human environment and negatively impacts human health and social wellbeing. Further, the spread of Odours in the neighborhoods around industrial regions can exacerbate social unrest and lead to public complaints about the quality of the air. Objective: To conduct and gather a community perception of Odour pollution caused by industrial sources and the health status of those population living near and around the source. Methods: The searches were conducted in March, June, September in 2022 and January and February in 2023. Data were collected by means of questionnaires at 10 sites near and around the industrial area. This study analyses comments from the people living within 1 to 15 km radius around an industrial area to gauge and determine how they perceive and experience being impacted by smell pollution. In order to ascertain the impact of industrial area Odour on social, health, and comfort levels, one aspect of the study comprised a perception survey. The disagreeable Odours' magnitude, persistence, and intensity were controlled by the other component. Results: From this study, 140 people responded. The results demonstrated that the strong disagreeable smell was normally experienced in summer. The findings also demonstrated that the industrial area smell had caused daily discomfort and continuously. Because the respondents experience a variety of unpleasant Odours that negatively affect their perception of their quality of life, the data from the research allow us to state that certain smells are so oppressive that they may force the need to leave the place of living. Conclusions: Results highlight the significance of smell pollution for the population living near and surrounding industrial odour sources in terms of public health. The limited evidence for the majority of results supports the need for high quality epidemiological researches on the relationship between odour pollution and its effects on human health. In conclusion, the analysis of the smell impact demonstrates a substantial effect on the residents of the area under study. The impact might be felt up to 15 kilometers away, especially in the closest area. Recommendations: It is essential that the relevant authorities conduct mitigation measures, and these pollutants must be thus controlled and regulated. While formulating legislation or making choices concerning industrial regions that also provide environmental preservation, policymakers should take public perception into account.

Assessment of Ground Water Pollution by Heavy Metals in Some Residential Areas in Kurdistan Region of Iraq
Environmental Science Archives (القضية : 2) (الحجم : 2)
Groundwater is a precious resource, and the life of humans depends on its quality. Public health is extremely concerned about the contamination of groundwater with heavy metals that come from either anthropogenic or naturally occurring soil sources since it can have detrimental impacts on both plant and animal life. The main objective of the present study was to determine and assess the concentration of heavy metal contamination in groundwater and to understand potential sources of contamination. Heavy metals such as Zn, Cu, Pb, Mn, Fe, and Cd are examined. Atomic Absorption Spectrophotometer (AAS) testing was done on groundwater samples that were taken from 10 wells in the study area. In groundwater samples, physical factors, including Electrical Conductivity (EC), Total Dissolved Solids (TDS), and metals like Cd and Pb were found to be over the allowed levels advised by international standards. The analysis revealed that the levels of Cd and Pb in the groundwater samples exceeded those recommended by the World Health Organization, Environment Production Agency and Iraqi standards. According to the findings, the maximum concentrations of Cd, Pb, Zn, Cu, Mn, and Fe were, respectively, 0.693, 0.42, 0.402, 0.0851, 0.068, and 0.04 mg/L. The groundwater samples from the research area demonstrated levels of the heavy metals in the following order: Cd> Pb> Zn> Cu> Mn> Fe. It was concluded that two heavy metals, cadmium and lead, and the percolation of dissolved salts were to blame for the groundwater's declining quality. Due to elevated amounts of harmful metals, the community's groundwater is therefore dangerous for drinking in some areas. It was recommended that either chemical precipitation, ion exchange, or reverse osmosis be used on a regular basis to treat the heavy metal concentration in groundwater sources.

Eurasian Chemical Communications (القضية : 10) (الحجم : 4)
The aim of this study is to estimate the evolution of some greenhouse emissions from Kwashe municipal solid waste landfill in Kurdistan Region, Iraq. The emission of gasses as CH4, CO2, CO, O2, O3, and H2S from the landfills in three sites was measured by the Drager multi-gas detector X-am 5600. The formation of CH4 inside the landfill body is spatial according to the load of the buried organic waste, the degree of organic waste moisture content, the spatial pH, and temperature within the landfill body, and further found to be higher thousands fold over its over save ranges in the third site. The liberation of CO2 is greater than its normal background in the atmosphere as 0.03% in three sites, especially in the third site to reach its risk level and at least hundred times greater than the normal ranges of carbon dioxide in the atmosphere. These reflect the high load of organic waste greater than the half and most of decomposition is carried by aerobic respiration. CO level in site 3 recorded the highest values in the first week and remained over the normal range till the end of investigation. The ozone formation ranges between 0.01 to 0.05 ppm and there is a parent difference between the sites. The highest emissions of H2S were noticed in site 3 and the peak was recorded in the first week of observation at 5 ppm. Then, the liberation continued after 4 weeks to 8 weeks, indicating that the load of wet organic waste deposition is concentrated on site 3.

Leachate is a major problem created from municipal solid waste (MSW) landfills and is considered the worst source of surface water and groundwater pollution. Kwashe industrial area as one of the most fast developing and polluted industrial area in Kurdistan region with many factories has a large solid waste separation factory that receives approximately 900 tons of municipal solid waste, out of which about 50% is organic kitchen waste. Samples of leachate were randomly collected from different sites downward drain of landfill and treated by aeration and filtration processes over a month. The results revealed that the soil was affected highly by soluble salts like Na and K from landfill; consequently, the electrical conductivity was 6.37(ds/m), 6 folds greater than the acceptable ranges. The primary treatment of landfill leachate by aeration and filtration reduced all heavy metals to acceptable ranges except Fe and Al, which remained relatively high over allowable ranges because the behavior and reaction of heavy metals in leachates is complicated as many acids are formed during the acidogensis of organic waste biodegradation that increases the solubility of these cationic heavy metals. The extractable forms of calcium, magnesium, sodium, potassium, sodium, and lithium are within acceptable ranges, which indicated not being enough to cause a threat in deteriorating soil and environmental chemistry. The results also showed that there was a close correlation between landfill leachate content of heavy metals and soil content affected by this leachate of Zn, Fe, Cu, Al, and Co at (P ≤ 0.01), but the soil downward landfill leachate fortunately did not reach the hazardous limits of their content in heavy metals and also did not exceed the standard ranges in soil.

Association of Cell Biology Romania (القضية : 03) (الحجم : 25)
This field study relied on collecting data related to the actual number of working hours of the power generating stations and their requirements from the fuel and the amount of the carbon dioxide emitted from these power plants because of burning diesel that contaminates our environment. The study showed that the Kurdistan region of Iraq and the province of Duhok suffer from the phenomenon of electricity power cuts in the government every day, to meet citizens’ needs for this power outage, civil power generators work side by side with state power transmission stations. Because of this process, which has been ongoing for over ten years, the size of air pollution with a continuous increase in carbon dioxide emissions, which lead to the removal of oxygen gas in the atmosphere because of emissions of carbon dioxide caused by the operation of the huge number of these generators, which accounted to be (1814) generators, which operate on fossil fuels (Diesel) and produce energy (373,818 kW/hour). The total capacity of the minimum production of energy per generator for a daily working is (8) hours, Where the amount of production or emission of carbon dioxide from these generators is (1,247,595.6) kg / hour. Besides the amount of thermal pollution caused by the cooling of these generators cold water, which cause pollution of aquatic ecosystem because of the installation of some of these generators on the shores of the river or some water tables in some districts and villages of the province which adversely affect the living organisms that live in those watersheds. These generators are a common source of noise pollution which bring disturbance to citizens living near some of these generators. Besides the other pollution caused by these generators, namely the visual pollution resulting from the supply of unplanned, random electric wiring and linking it to the homes of citizens, which affects the psychological comfort while looking at such beautiful scenery. All these types of pollution negatively influence health and the environment.

International Journal of Advanced and Applied Sciences (القضية : 8) (الحجم : 3)
The present investigation deals with the physico-chemical analysis of Zea River which passes through the Deralok City, an agricultural town of Duhok province. The objective of the study was to provide baseline information on its physical and chemical characteristics as well as evaluate its water quality. Water samples were collected during dry and wet seasons from seven stations and analyzed for various physico-chemical parameters. Assessment of temperature, pH, Dissolved Oxygen, total alkalinity, turbidity, chloride, hardness, dissolved oxygen, calcium, Sulphate, total dissolved solids (TDS), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and Electrical Conductivity were carried out monthly during November, 2014 to June, 2015. Results showed significant alterations in the physicochemical parameters. The analyzed data of water body was interpreted in relation to pollution status and biodiversity indices for assessment of aquatic fauna. Atmospheric temperature ranged from 2.12 to 45.25 (ºC). Water temperature ranged from 10.71 to 16.01 (ºC). pH ranged from 7.27 to 8.73, dissolved oxygen from 7.53 to 9.01 (mg/l), electrical conductivity from 316 to 398 (μS/cm), total dissolved solids from 202 to 255 (mg/l), turbidity from 86 to 92 (NTU), total hardness from 206 to 216 (mg/l), total alkalinity from 58 to 76 (mg/l) and total acidity (53–83 mg l-1), BOD (2.7–3.7 mg l-1), COD (1.7–2.1 mg l-1). Results show that there is no serious problem regarding the parameters checked in this study. So, the water can be used as drinking water for Deralok city and another city without any serious problem. The results suggest that refuse disposal, fertilizer use, and natural phenomena e.g. soil erosion; flooding, etc. may have contributed in various ways to the impairment of the water quality of the studied sites. Although the results do not indicate adverse pollution status of any of the sites, they provided the need for further investigations and monitoring. The water from the river which is called Zea, travels from turkey to Kurdistan in a small city called Deralok it also goes through the middle of the city. This separates the city into 2 pieces. From Deralok the river goes through many villages and woods then it joins with another river called the blue (shin) river. Also the Zae River is 75km far away from the province of Duhok.

POTENTIAL AND CONSTRAINTS FOR ECOTOURISM DEVELOPMENT IN KURDISTAN
Potential for tourism in Kurdistan is, recently flourishing at least on the domestic front. Many indicators show tourism as today's fastest growing industry; either measured by gross output, value added capital investment, employment or tax contributions. Natural areas and features in Kurdistan are yet to be explored to the fullest and have serious potential for developing international tourism in a sustainable manner. Therefore, ecotourism development may become a reality in near future. It will only happen with proper policy implementation, development, management and planning vital to maximize this potential and thus bring positive economic, social and cultural benefits as well as environmental protection as a whole. Destination development and marketing for the tourism industry might be recognised by the Kurdistan regional government as a primary economic sector for its short and long term future plans. When other regions around the world promote research and services for developing ecotourism, the same can be applied for the land of civilizations and historical features that Kurdistan possess, which is also home for the rich and diverse flora and fauna.
