摘要
农药在水中的光化学降解是重要的降解途径,其过程和产物对农药药效、代谢、毒性及环境影响很大。综述了影响水体中农药光解的不同因素,包括光源、pH、光敏剂、光猝灭剂等,分析了农药在水体中光解产物的分离和鉴定,并讨论了水中农药光解的意义。
Photochemical degradation of pesticides in water is an important transformation pathway in the environment.The processes of pesticides photedegradation play a key role in assessment of their ecological risks. The importantfactors affecting photodegradation of pesticides in water were reviewed, including selection of light, pH, photosensitizer,photoquencher, etal. Separation and identification of photodegradation product, meaning of photodegradation of pesti-cides in water were also discussed.
