全氟化合物的分布、累积及生态毒理学效应

Distribution and Accumulation of PFCs and Ecotoxicological Effects

全氟化合物(Perfluorinated compounds,PFCs)污染在全球范围内已普遍存在,其在环境中的浓度增长迅速,受到人们越来越多的关注。环境中PFCs的迁移转化规律决定其环境效应,是进行环境和健康风险评价的基础。目前关于PFCs的研究主要集中于水体及生物体内PFCs的分析检测,对其生态毒理效应的研究尚处于初步阶段。本文介绍了PFCs研究现状,综述了PFCs在环境中的分布模式、生物体内的蓄积规律以及环境中PFCs的生态毒理效应等方面的最新研究进展,同时也阐述了PFCs污染对人体健康的影响,并提出了未来PFCs研究亟待解决的问题。

The pollution of perfluorinated compounds （PFCs） exist in environment worldwide with rapid increasing concentration, causing an extensive attention. The migration and conversion of PFCs depend on their environmental effects, which are the basis of risk evaluation for environment and human health. However, the current research on PFCs focuses mainly on analysis and detection in waters and organisms, the studies on ecotoxieologieal effects of PFCs are still in initial stage. In this paper, the status quo of PFCs research was introduced and the progresses in the respects such as distribution, bioaccumulation and ecotoxicologieal effects in the environment were summarized. Meanwhile, the impact of PFCs on human health was discussed. Finally the problems needed to be solved in this field in future are proposed.
