| 中文摘要: |
| 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7997 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,3571%的水体为慢性无风险,6429%的水体为慢性低风险。 |
| 英文摘要: |
| 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 7997 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 3571% of the water bodies were chronic and risk free, and 6429% were chronic low risk. |
