| Abstract: | The processes of photodegradation of pesticides play a key role in the transformation of pesticides in the marine environment.In this paper,the reaction types and mechanisms of photodegradation of pesticides in seawater and their influencing factors such as irradiation condition,solution media,pH,heavy metal ions and photosensitizers are introduced.The photodegradation products of pesticides and their analytical methods are briefly summarized.Some existent problems in the study of the photodegradation of pesticides are pointed out.Further research aspects of photodegradation of pesticides in future are suggested. |
