沉积物中溴代阻燃剂的研究进展

溴代阻燃剂(Brominated flame retardants，BFRs)是一种能够使易燃材料降低燃烧性能的助剂。随着其大量生产和使用，BFRs已经成为多种环境介质中普遍检出且极具生态风险的持久性有机污染物（Persistent organic pollutants，POPs），对生物体和环境产生危害。因此，研究典型环境介质中BFRs的归趋行为和检测方法，对其风险消减具有重要的科学意义。BFRs在水体中的溶解度小，进入水环境易富集于沉积物中。本文对BFRs的最新研究动态进行综述，比较不同地区沉积物中BFRs的污染现状，并且介绍了分析BFRs的样品前处理技术、仪器检测方法和修复技术，并对今后BFRs的研究方向进行讨论和展望。

Research progress of brominated flame retardants in sediments

Brominated Flame Retardants (BFRs) are auxiliary chemicals which can reduce the flamability of materials. With the mass production and use of BFRs , it has become one of highly ecological risk persistent organic pollutants(POPs),which is harmful to the organism and environmental and can be universally detected in the environmental medium. Therefore, to study the environmental behavior and detection method of BFRs in typical environmental media, this is of great scientific significance in reducing the risky of the BFRs. The water solubility of BFRs is small, in the water environment, it is easy to stack in the sediments. In this paper, the latest research trends of BFRs are summarized, and different pollution status of BFRs in sediments are compared, meanwhile, the pretreatment technology, instrument detection methods and repair technology of BFRs are introduced, and the research direction of BFRs is discussed and forecasted.
