Distribution Characteristics and Risk Assessment of Organic Pollution in a Coal Chemical Plant
Taking a coal chemical plant as the research object,the characteristics and spatial distribution of soil organic pollution in the coal chemical plant were clarified through field sampling and detection analysis.The soil pollution was analyzed according to the distribution of key pollution areas in the plant.At the same time,soil pollution risk assessment of or ganic pollutants is carried out to assess whether their health risks are acceptable.The results showed that petroleum hydrocarbon(C10-C40),polycyclic aromatic hydrocarbons(PAHs)and benzene series,exceeded the standard of organic compound in the site,and the content of pollutants gradually decreases with the deepening of sampling depth.The health risks of organic matter in soil and groundwater were unacceptable.The site is a contaminated site,and the next step of remediation or risk control work needs to be implemented.
