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
摘要
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.
