短链氯化石蜡(SCCPs)的分析方法、环境行为及毒性效应研究进展

Research advances in analytical methods, environmental behaviors and toxic effects of short chain chlorinated paraffins (SCCPs)

短链氯化石蜡(SCCPs)组成复杂,具有远距离环境迁移的能力、环境持久性、生物蓄积性和一定的生物毒性,已被提议列入《关于持久性有机污染物的斯德哥尔摩公约》的附件A、B或C.我国是氯化石蜡生产和使用最多的国家,且尚未限制SCCPs的生产.几个研究已揭示了SCCPs在我国的环境中存量较高,因此应对其所引起的生态环境风险和人体健康风险给予关注.本文重点评述了SCCPs的分析方法,包括样品前处理、色谱分离、质谱检测、定量分析及国际实验室分析比对情况,同时也对SCCPs的环境行为、生物累积和毒性效应进行了综述.

Short chain chlorinated parafins （SCCPs） are a group of complex mixtures. They can undergo long-range transport and exists in the environmental matrix persistently. At the same time, they can be accumulated by organisms and then induce some toxic effects. Therefore, SCCPs have been proposed to be listed in Annexes A, B or C of the Stockholm Convention on Persistent Organic Pollutants. China is the largest producer and consumer of chlorinated paraffins. Nowadays, in China the production of SCCPs has not been prohibited. Several researches have indicated the high concentrations of SCCPs in Chinese environment. So the ecological risk and human health risk induced by SCCPs pollution should be concerned. In this paper, the analytical methods of SCCPs, including sample preparation, chromatography separation, mass spectrometric detection, quantification and interlaboratory study, were critically reviewed. Meanwhile, the environmental behaviors, bioaccumulation and toxic effects of SCCPs were summarized.
