Abstract:The site contaminated by pesticides has the characteristics of complex pollution components, prominent odor problems, difficult restoration and treatment, and high risk of safe utilization, which are the key soil environmental problems to be solved urgently. During the 13th Five-Year Plan period, the treatment technology of pesticide polluted sites in China has been improved, and the safe utilization model has initially formed. On the basis of summarizing pesticide site treatment technologies and successful cases, a technical system for pesticide contaminated site treatment was constructed according to pollutant types and soil characteristics, and a safe utilization model and scheme based on land use planning, sensitive receptors and pollutant types were proposed. It not only can guide the pesticide site pollution risk control, treatment and restoration, but also can provide the basis safe utilization and scientific management for pesticide contaminated sites.
