In order to obtain the safety threshold of pesticides for protecting aquatic ecosystem. The Predicted No Effect Concentration of Mancozeb,Chlorothalonil and Dichlorvos were extrapolated by the evaluation factor method and the Species Sensitive Distribution,respectively. The extrapolation result of evaluation factor method shows that PNEC of Mancozeb was 0. 220 ~ 5. 800μg/L,Chlorothalonil was 0. 010 5 ~ 0. 700μg/L,and Dichlorvos was 0. 000 700 ~ 1. 000μg/L,while the results of Species Sensitive Distribution shows that PNEC of Mancozeb was 41. 784μg/L,Chlorothalonil was 1. 190μg/L,and Dichlorvos was 13. 081μg/L(vertebrates) 、0. 002 62μg/L(Invertebrates),Invertebrates were more sensitive than vertebrates to dichlorvos.
