摘　　要：拟除虫菊酯类农药的广泛使用,引起的环境问题及农业生产与日常生活中的安全问题日益突出。本文综述了拟除虫菊酯类农药的光降解行为,包括自然光照降解、紫外光照降解、光催化降解、光照下的微生物降解及辐照降解;探讨了影响光降解的因素,如光照强度、p H、氧气、溶剂、金属离子、腐殖质,及与其他农药的交互作用等。最后,总结了拟除虫菊酯类农药的光降解机理。Because of widespread use of the pyrethroids pesticides, the environmental problems and safety issues of agricultural production and daily life have being become increasingly prominent. This paper reviewed the photodegradation behavior of the pyrethroids pesticides, such as natural light degradation, UV irradiation degradation, photocatalytic degradation, microbial degradation under illumination and radiation degradation. And the factors affecting of the photodegradation, such as light intensity, pH, oxygen, solvent, metal ions, humus, interactions with other pesticides, etc. were discussed in the paper. In the end, the paper analyzed the mechanism of pyrethroids light degradation.
