Abstract:
China is a big producer and user of pesticides. With the in-depth implementation of China’s policy of “returning two into three” and “retreating into the city”, a large number of soils are contaminated by pesticides due to closure and relocation of enterprises in many suburbs. High concentrations of highly toxic composite pesticides remain in the soils, which poses serious risks to ecological environment and human health. At the same time, with the promulgation and implementation of the Law of the People’s Republic of China on Soil Pollution Prevention and Control, it is necessary and urgent to accelerate the research on remediation technology for contaminated soil. Based on the current situation of pesticide contaminated sites in China, this review summarized the research progress of soil physical-, chemical- and bio-remediation technologies in China in recent years. At the same time, based on the shortcomings of existing researches, the development trend of future remediation technology was proposed. This review can provide a scientific basis for the development of green sustainable remediation technology for pesticide contaminated soils in China.
