摘要
有机磷农药一方面能有效防治农林病虫害,造福于人类,另一方面也给人类赖于生存的环境带来危害。有机磷农药在环境中的降解性能,是评价有机磷农药对环境危害影响的重要指标,有机磷农药在环境中的残留时间越长,对环境的污染及其对各种环境生物,甚至对人类的危害也越大。有机磷农药在环境中的降解,包括微生物降解、光化学降解、化学氧化降解和超声波降解。不同的降解方式,由于影响因素和相关机理的不同,各种降解特性存在着一定的差异。
The organophosphorus pesticides may on the one hand, can effectively protect agriculture and forestry from pests and diseases, benefit the humanity, on the other hand, do a lot of harm to environment. The degeneration performance of rganophosphorus pesticides in the environment is an important index of appraises the ganophosphorus pesticides bring harm influence to the environment, the longer the ganophosphorus pesticides leave in the environment, the severer pollution to the environment and various biology, even give greater harm to human. Organophosphorus pesticides＇ degradation in the environment, including micro- bial degradation, photodegradation, chemical oxidation degradation and ultrasonic degradation. The different degeneration way, as a result of the influencing factor and the related mechanism＇s difference, each kind of degeneration characteristic has certain difference.
