摘要
搜集筛选氟虫腈对3门10科共15种本土淡水生物的慢性毒性数据,基于Boltzmann、SGompertz、Sigmoid和SRichards等4种分布模型,在系统尺度上构建氟虫腈的物种敏感度分布曲线,运用最优函数推导出淡水环境中氟虫腈的长期水质基准值为79.97 ng/L。利用熵值法评估了国内14处淡水水体中氟虫腈的长期生态风险,风险表征结果显示,35.71%的水体为慢性无风险,64.29%的水体为慢性低风险。
This study collected and screened out the chronic toxicity data of fipronil on 15 native freshwater organisms from 10 families and 3 phyla.Based on the four distribution models including Boltzmann,SGompertz,Sigmoid and SRichards,it constructed a species sensitivity distribution curve of fipronil at system scale,derived the long-term water quality criteria of fipronil in freshwater environment as 79.97 ng/L using mathematical optimization function.It evaluated the long-term ecological risk of fipronil in 14 freshwater bodies in China by entropy method.The results showed that 35.71% of the water bodies were chronic and risk-free,and 64.29% were chronic low-risk.
