The main objective of the present study is to spatially evaluate the water contamination of Khabur River, before it arrives in Zakho City, inside the city, and after it leaves the city of Zakho by heavy metals. Also, the seasonal effects of Zakho municipal wastewater discharged in the Khabur River were detected in this study. The results showed that some heavy metals, such as Ni, were not detected in all studied samples in this study due to their low concentration levels. It is indicated that heavy metals are statistically affected by spatial location and high amounts were detected after leaving, compared to before entering the city which indicates that municipal wastewater is the main source of metal pollution. However, all water tests met the WHO's authorized limits. The average detected concentrations of copper, iron, manganese, and lead ranges from 0.003 to 0.025 mg/L, 0.000 to 0.054 mg/L, and 0.057 to 0.112 mg/L, and 0.014 to 0.135 mg/L respectively, while the highest concentrations of copper and iron were recorded significantly in Bedare (0.025 mg/L, 0.054 mg/L) respectively. The highest concentration of Lead (Pb) was detected in Chamtre and Tawke 0.117 mg/L and 0.135 mg/L respectively and this increase may be due to the presence of oil in the discharged industrial wastewater, in this village. Regarding season’s effects, higher mean concentrations for Mn 0.13423 mg/L, Fe, and 0.04208 mg/L were recorded in the autumn season. However, copper and lead had higher mean concertation 0.02389 mg/L, and 0.097 mg/L respectively, during the winter season, while the lowest mean concentration of copper was recorded in autumn, and lead in the summer season had a minimum concentration. There was a significant difference (P <0.01) in the seasonal variation of Cu, Fe, Mn, and Pb

Wastewater contains poisonous metals which can be moved and accumulated in plants before entering the human body through the food chain. The aim of this research was to investigate the concentrations of toxic metals such as Nickel (Ni), lead (Pb), and copper (Cu) in wastewater, celery plant and farmlands soils of Duhok city Kurdistan of, Iraq. The heavy metals accumulation in the Celery plants, soil and water samples were analyzed by using an atomic absorption spectrophotometer. The results obtained showed that the mean concentrations of Pb, Ni, and Cu in the wastewater and Celery plants samples ranged from 0.45±0.08 to 5.95±0.2, 0.18±0.01 to 1.95±0.28, 0.02± 0.01 to1.13±0.23 mg/L respectively. The pattern of metal buildup in wastewater-irrigated soil is in the order: Cu > Pb > Ni, and the mean concentration of Pb, Ni and Cu in soil ranged between 21.68±0.42 to 118.57±0.07, 1.27±0.47 to 5.70±0.23, 1.28±0.24 to ± 15.12 0.53 mg/kg-1, respectively. While the mean concentration of Pb, Ni and Cu in celery leaves ranged from 1.04±0.22 to 5.22±0.60, 0.52± 0.22 to 4.31± 0.12, respectively. 1.34 ±0.22 to 19.47±0.82, 1.23±0.04 to 7.29± 2.53, 1.01±0.05 to 5.76±1.32 mg/ kg-1, respectively. According to this study, roots contain more heavy metals than leaves. According to the findings, a few of the sampling sites had Pb, Ni, and Cu values that were exceeded the permissible concentration. Celery plants cannot be planted in the Duhok Valley to prevent excessive heavy metal exposure to human health through vegetables, where the main irrigated water source is sewage from the local municipalities. Celery plant irrigation with wastewater has much greater levels of heavy metals than the controls.

Samples of water were collected from the Khabur River in Zakho city in Iraqi Kurdistan Region in three seasons, the summer, autumn, and winter of 2021, at three different locations, before arriving at the city, inside the city, and after passing the city, and some Physio-chemical properties of water were determined to evaluate the spatial and seasonal variation effects on the renowned Khabur River properties. The result revealed the dissolved oxygen DO, biological oxygen demand is significantly (p<0.01) influenced by the summer season than autumn and winter, as the high temperature minimizes the dissolvability of oxygen necessary for life in the water, however, the level of BOD in Khabur river in three seasons not exceeded the recommended level of WHO and Iraqi slandered 3 mg/l. The pH of the Khabur River is not significantly affected by seasonal changes, while EC is significantly affected by seasonal variation. The alkalinity of the Khabur River is significantly higher in summer than in autumn and winter, and the opposite of almost all the studied parameters that increased in winter. The river has a total hardness greater than 200 mg/l as well as total calcium and magnesium. Hardness is significantly high in winter, as the dissolution of both Ca and Mg from bedrock and soil is increased by the action of heavy rainfall on the eroded soil. Regarding the spatial variation, the most studied parameters of the Khabur deteriorated when the river enters Zakho city, as approximately all the sewage water of this city is discharged into the river without any proper treatment.

Automobile exhausts can contribute to accumulation of Toxic metals in roadside soil. The soil pollution by toxic metals from transportation sources has become a serious environmental threat. The main objective in this research work was to assess the roadside soils contamination with Zn, Cd, Pb, Cu and Ni due to vehicular emissions. The samples were digested using wet method and heavy metals were analyzed using Atomic Absorption Spectrophotometry Technique. Monthly samples were collected from the agriculture soil around roadside during the period December to July 2018. A total of 96 soil samples were collected from different locations of villages around national roadside within Zakho District, Duhok governorate, Iraq. 48 samples were collected at 20 m from the roadway edge and 48 samples were collected at 40 m from the roadway edge. Physical and chemical factors believed to affect the mobility of toxic metals in the soil samples of the study area were tested such as; conductivity, TDS, pH and organic matter. The results showed that the soil pH was from 6.7 to 8.3and the organic matter percentages were from (0.8 to 2.6) EC, from (683 to 1475) µs/cm and TDS was from (437 to 944) mg/l. The soil samples of distance (20 and 40) m from roadside. The results of distance (20 and 40) m from roadside observed that concentration of Pb, Cu, Zn, Cd and Ni was found to vary between (1.1-7. 8 ) (7.7-16.4) (14.2-44.4) (0.10—0.37) (5.8-17.5) (1.0-4.5) (4.4-13.9) (10.1-38.5) (0.03-0.26) (4.7-13.7) mg /Kg respectively. This paper indicated that the heavy metals content decreased with increasing distances along the roadside.

Heavy metals (Pb, Cu, Zn Cd, and Ni) contamination in wheat plants (Triticum aestivum L.) And agricultural soils adjacent to the national highway-with in Zakho district, Iraq has been studied by the analysis of plant and soil sample. Wheat plants were sampled during maturity at 12 locations in July 2017. The result observed that content of five toxic metals was found significantly higher in roots than in the stem parts of wheat plants. On the other hand, the winter wheat transported five toxic metals very weakly from root to stems in the various agricultural soils. The general order for the accumulation of studied metals in wheat plants was found to be Zn > Cu > Ni >Pb >Cd. The mean concentration and standard deviation of toxic metals in the roots and stem of wheat plants varied between (0.1317 ±0.1677) (1.744 ±0.979) (2.857± 1.301) (0.02329 ±0.02149) (1.114 ±0.291) (0.03143 ±0.01952) (0.909 ± 0.854) (0.951±0.769) (0.006 ±0.001718)(0.2957±0.2411) mg/kg,respectively. The results observed that the study sites pollution is mostly due to vehicular emissions. On the other hand, the results observed that vehicular emissions can contribute to accumulation of toxic metals in roadside soil and wheat plants. However concentrations of all the heavy metals obtained were below the maximum permissible limit of toxic metals in plants set by WHO. Keywords: Roadside soil, national high ways, winter wheat, roadside wheat.

Background: Occupational exposures represent complex mixture of genotoxic agents. Benzene is one of the major organic product, people with chronic exposure to this organic product are exposed to many malignant disorders. People who work in Petrol station are consistently exposed to the dangerous components of petroleum through inhalation or direct contact with their skin. Objective: The aim of this study was to evaluate the potential cytogenetic damage and micronuclei frequency associated with occupational exposure to benzene among petrol station workers by using Micronucleus assay. Materials and Methods: The study groups included twenty five occupationally exposed petrol station workers and twenty five age matched controls were recruited and evaluated for genetic damage. Exfoliated Buccal cells were collected from both groups by using the sterile brush. Slides fixed in ethanol and stained with Giemsa stain and 1000 cells were studied by using a light microscope. Statistical analysis for data interpretation performed by Student’s t‑test, and P < 0.05 was considered statistically significant. Results: As compared to control subjects, significant high level of micronuclei frequency was found in the workers exposed to benzene (4.65±2 and 1.22±7 respectively). Period of exposure also showed considerable effects (P<0.05) on micronuclei frequency, while effect of age was non-significant (P>0.05). In this study, both Control and workers with history of Tobacco smoking and alcohol were excluded. Conclusions: The results of our study concluded that benzene have the potential to increase micronuclei frequency in the exposed subjects. The study also suggested that protective strategies should be implemented by the concerned authorities to minimize exposure to fuel.

Water samples from twenty wells and twenty springs were assessed to determine whether samples from springs and wells have similar concentrations of selected characteristics, including electrical conductivity (EC), total alkalinity (TA), total dissolved solids (TDS), pH, Sulphate (SO4 2-) Nitrate (NO3-), total hardness (TH), magnesium (Mg2+) and Calcium (Ca2+). Comparisons were made between concentrations of chemical and Physical characteristics in water samples from springs and wells within the same aquifer. Samples were collected monthly from the wells and springs during March 2017 to February 2018. The samples were tested for chemical and Physical characteristics according to the standard methods of American Public Health Association. There were significant differences between all data selected from springs and wells except Mg and DO. In addition, no significant difference was found between the mean pH values. The results indicated that the water samples lie within the permissible limits as compared with WHO (World Health Organization) for drinking uses, however some samples of water are without the permissible limit such as EC, TDS, and TH. The spring water samples were found to be better than well water samples. The results showed that eight wells and four springs’ water samples requires treatment for drinking uses.

Spring water is the main source of water providing life to people in the mountain region especially in the Kurdistan region northern Iraq. Spring water is the common source of public water supply in most rural communities of developing countries such as Duhok city. Studies were carried out between January and July 2017. The rural communities in Barware Sheree depend on spring water for their domestic needs. The groundwater quality of District Barware Sheree has been assessed to see the suitability of groundwater for drinking and applications. In order to characterize springs water quality in Barware Sheree district, nineteen springs were selected to represent their water quality. Monthly sample was collected from the springs for the period between January and July 2017. The physical and chemical parameters such as pH, electrical conductivity (EC), total dissolved solids (TDS), total alkalinity (TA), Nitrate (NO3-), total hardness (TH) Calcium (Ca2+), magnesium (Mg2+), Chloride (Cl-), Nitrate (NO3-), Sulfate (SO4 2-) were analysed to know the present status of the spring water quality. The results were compared with World health organization standard. The results show the difference between the spring water quality.in the measured parameters. The water quality of all springs was soft water, except Giraye springs which have TDS more than 500 mg/l, the levels of conductivity (730) μs/cm. pH of all springs ranged between (7.4- 8.4) these pH values were alkaline side, it can be seen all the sampling sites had pH level falling with the recommended range of (6.5-8.5), the sulfate concentration in all springs of the study area was below the guidelines of 250 ml/l. Nitrate values were below the guidelines of 45 mg /l, the research concluded that Barware Sheree springs within the studied area were of conduit type as the exhibit monthly variation in temperature of water quality.

In order to characterize the waste water in Duhok valley in Duhok governorate, during 25km, seven sites were selected in Duhok valley, to represent their water quality. Monthly samples were collected from the Duhok valley for the period from, April to September, 2015. The qualitative study of Duhok valley water tested, as considered one of the main sources of water pollution for Musol Lake. The physical and chemical test for water samples are taken from different locations in Duhok valley. To know the degree of pollution, and the impact of self-purification processes to improve water quality before arriving to the Mosul Lake, and the indicated results of the study a lack of dissolved oxygen in the water (DO). And high organic load values, (BOD) and most of the bad qualities during water passage within the city of Duhok, while meat a significant improvement in the quality of water downstream before arriving at the dam Lake, is attributed to the effect of operations of self- purification ability of water. In spite of salinity problems and toxicity, the quality of water is suitable for irrigation crops on both sides of the valley .The all samples were tested for conductivity, TDS, pH, total hardness, chloride, alkalinity, sulfate, BOD, and phosphate, according to the standard methods.
