摘　　要：六溴环十二烷(HBCDs)是一种被大量生产且广泛使用的溴化物阻燃剂,属于新型持久性有机污染物。环境中HBCDs分布广泛且含量跨度大,准确分析测定其在环境介质中的含量对环境污染控制具有重要意义。对目前我国各地沉积物中HBCDs污染分布进行了总结。在文献调研的基础上,对沉积物及相关基质中HBCDs的前处理、分离和检测等关键技术进行了对比和分析。此外通过对现有HBCDs标准物质来源调研,对HBCDs准确定量的溯源问题进行了讨论,并且对HBCDs未来的测量和监测工作提出了展望。Hexabromocyclododecanes(HBCDs) is a mass-produced and widely used brominated flame retardant, which is a new type of persistent organic pollutant. HBCDs are widely distributed in the environment and their contents span a wide range, and accurate analysis and determination of their contents in environmental media are of great significance for environmental pollution control. This paper summarized the pollution distribution of HBCDs in sediments across China.Based on literature research, the key techniques of pretreatment, separation, and detection of HBCDs in sediments and related matrices were compared and analyzed. In addition, by investigating the source of HBCDs reference materials, the traceability of HBCDs for accurate quantification was discussed, and the future measurement and monitoring work of HBCDs was put forward.
