The likelihood of toxic gases occurring within a specific timeframe and location determines the ikelihood 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 tragica lly 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 invalu able 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. Toenh ance the accuracy of risk assessments for disasters involving toxic gases, this study proposes amethod that considers both gas dispersion modeling and evacuation dynamics. Identifying effective methods for reducing toxic gas pollution and its adverse effe cts 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.
