环境空气中短链氯化石蜡研究进展

短链氯化石蜡(SCCPs)是碳链长度为10至13个碳原子的正构烷烃氯代衍生物。SCCPs具有持久性、生物累积性、长距离迁移能力、以及毒性作用。SCCPs已被《关于持久性有机污染物的斯德哥尔摩公约》增列为持久性有机污染物审查范围内,引起了全球关注。SCCPs在环境各介质及生物体内均有检出,近年来,在室内空气和灰尘中也检出了大量SCCPs,其已成为人体暴露的一个重要来源。本文就大气环境及室内空气与灰尘中氯化石蜡(CPs)的采样与分析方法、污染水平与来源,及人体暴露概况进行了综合阐释,以期为我国大气和室内环境中CPs的研究工作提供参考。

Research Progress of Short Chain Chlorinated Paraffins in Environmental Air

Short chain chlorinated paraffins (SCCPs), which are chlorinated derivatives of n-alkanes, are a complex mixtures that include 10 and 13 carbon atoms. SCCPs attract global attentions due to their persistence, bioaccumulation, long-distance transport ability, and toxicity. They have been listed as candidate persistent organic pollutants in the Stockholm Convention. SCCPs have been ubiquitously detected in various environmental matrices. In recent years, indoor air inhalation and dust ingestion have been demonstrated to act as an important source of human exposure to SCCPs. In this study, the current available methodologies on sampling and analytical techniques, contamination levels, possible sources, assessment for human exposure to chlorinated paraffins (CPs) in atmosphere and indoor environment are critically reviewed. It is hoped that the work can provide references for the further researches of CPs in environmental air in China.
