摘　　要：六溴环十二烷(HBCDs)是一种添加型溴系阻燃剂,广泛应用于建筑隔热材料、纺织品涂层、电气和电子产品中.其为继多溴联苯醚、四溴双酚A之外的世界第三大溴代阻燃剂.HBCDs具有持久性有机污染物的长距离迁移性、生物累积性及毒性等特征,引起了全球关注.2013年5月HBCDs已被增列入《斯德哥尔摩公约》附件A中.HBCDs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HBCDs,其已成为人体暴露的一个重要来源.本文对大气环境及室内空气与灰尘中HBCDs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,并对其未来研究方向进行了展望,以期为我国大气和室内环境中HBCDs的研究工作提供参考.Hexabromocyclododecanes （HBCDs） are additive brominated flame retardants widely used as thermal insulators in building materials, in upholstery textiles, and in electronics. HBCDs have become the world＇s third most widely used brominated flame retardants after polybrominated diphenyl ethers and tetrabromobisphenol A. HBCDs have attracted global attentions due to their persistence, bioaccumulation, long-distance transport ability, and toxicity. In May 2013, HBCDs were added to Annex A of the Stockholm Convention. HBCDs have been ubiquitously detected in various environmental matrices and organisms. In recent years, indoor air inhalation and dust ingestion have been demonstrated to act as important sources of human exposure to HBCDs. In this paper, the current available methodologies on sampling and analytical techniques, contamination levels, possible sources, assessment for human exposure to HBCDs in atmosphere and indoor environment are critically reviewed. It is hoped that the work can provide references for the further researches of HBCDs in environmental air in China.
