| 摘 要： | 全氟辛烷磺酰(PFOS)是我国环境中广泛存在的一种全氟类污染物,对生态环境存在潜在威胁.本文采用PFOS对我国食物链中鸟类与哺乳动物的毒性数据,根据欧盟现有化学物质风险评价技术指导文件,对PFOS的食物链的预测无效应浓度(PNEC经口)进行推导,并初步对我国太湖水生食物链进行次生毒性风险评价.结果表明,PFOS的次生毒性PNEC经口为0.04 mg·kg-1.PFOS太湖水体9种鱼和1种食鱼鸟的次生毒性风险商均小于1.根据本文收集的数据,PFOS对太湖水生食物链的次生毒性风险较小.该研究为我国PFOS的次生毒性风险评价提供科学依据.

| Abstract: | Perfluorooctane sulfonic acid (PFOS) is one of perfluorinated pollutants.It is widely present in the environment in China and might pose a potential threat to ecosystem.According to the EU technical guidance document on risk assessment for existing substances,the predicted no-effect concentration (PNECoral) value of PFOS of secondary poisoning in food chains was derived with the toxicity data of the native species of birds and mammals in China.The risks of secondary poisoning for freshwater food chain in Taihu Lake were preliminarily assessed.The results demonstrated that the PNECoral value of secondary poisoning for PFOS was 0.04 mg · kg-1.The risk quotients of PFOS to nine fishes and one kind of fish-eating bird were all lower than the unity.According to the collected data in this article,the risk of secondary poisoning of PFOS for the freshwater food chain in Taihu Lake was small.The results would provide scientific foundation for risk assessment of secondary poisoning for PFOS in the environment of China. |
