摘要
按照《化学农药环境安全评价试验准则》的规定研究了毒死蜱在环境中降解的特性。结果表明,毒死蜱在壤土、粘土和砂土中的降解半衰期分别为23.9、12.6和9.8 d;在pH值4.0、7.0和10.0的水中的水解半衰期分别为22.4、18.9和0.6 d;在pH值4.0、7.0和10.0的水中光降解的半衰期分别为12.8、10.7和0.5 d。毒死蜱在环境中属于易降解的农药。
Degradation characteristics of chlorpyrifos in environment were studied according to ＂Experimental Guideline for Environmental Safety Evaluation of Chemical Pesticides＂. Results showed that the half-life of chlorpyrifos degradation in loam soil, clay and sand was 23.9 d, 12.6 d and 9.8 d, respectively, in water with pH 4.0, 7.0 and 10.0 was 122.4 d, 18.9 d and 0.6 d, respectively. Half-life of chlorpyrifos photodegradation in water with pH 4.0, 7.0 and 10.0 was 12.8 d, 10.7 d and 0.5 d, respectively, Chlorpyrifos was easily degraded in environment.
