Abstract: Based on the US EPA framework, together with the data obtained using ECOTOX and CNKI database on the acute toxicity of 3 typical pyrethroid pesticides and the responses of biomarker parameters, the present research identified their criteria maximum concentration (CMC) and criteria continuous concentration (CCC) of China national water quality criteria as 7.5 and 0.9 ng·L-1 for deltamethrin, 110 and 19 ng·L-1 for cypermethrin, and 21 and 3.5 ng·L-1 for fenvalerate, respectively. Biomarkers, such as SOD, CAT, AchE, MDA, GSH, DNA/RNA contents could reflect the ecotoxicological effect of the pollutants from various perspectives on multilevels, which could help predict the ecological risk of the pollutants more precisely. The present research provides scientific support for setting the national water quality criteria and controlling the risk of pyrethroid pesticides in China.
