摘要:

在US EPA水质基准制定指南框架基础上,利用从ECOTOX和CNKI数据库获取的3种拟除虫菊酯农药对中国淡水水生生物的急性毒性数据和生物标记物毒性数据,得出了基于多指标的中国淡水水体中溴氰菊酯、氯氰菊酯和氰戊菊酯的基准最大浓度(criteria maximum concentration,CMC)和基准连续浓度(criteria continuous concentration,CCC),分别为:7.5和0.9,110和19,21和3.5 ng·L-1。引入SOD、CAT、AchE、MDA、GSH、DNA/RNA含量等生物标记物指标,可以从多角度、多层次、多水平反映污染物的生态毒性效应,提出的基准值可以更加精准地预测污染物的生态风险。本研究可为水质基准推导方法的完善及拟除虫菊酯农药的水生生态风险控制提供参考。

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.
