The application of pesticides has promoted the development of Chinese agriculture and guaranteed the food security,but the irrational use of pesticides has led to the pollution of ecological environment.Clarified environmental behaviors such as migration,transformation and degradation of pesticides in the environment can provide a theoretical basis for risk assessment and risk control of pesticides.The environmental fate of pesticides in soil,water,environmental non-target animals and plants were described in this paper,and the factors affecting the environmental behavior of pesticides were analyzed.The main methods of pesticide pollution control were summarized,including physical method(adsorption method,membrane treatment method),chemical method(photocatalysis,Fenton,activated persulfate),microbial method and plant method.Finally,the future development direction of environmental behavior research and risk control of pesticides and their combined pollution were prospected.
