摘要
溴代阻燃剂以其优异的阻燃性能而在工业生产和日常生活中大量使用。这些外源性的化学物质因其蓄积性、持久性、生物毒性而对人类健康和生态环境造成威胁。微生物特有的降解代谢能力为溴代阻燃剂污染治理带来了希望。但是,目前有关溴代阻燃剂的微生物降解研究仍然很少。综述了国内外在溴代阻燃剂微生物降解方面的最新研究动态,包括厌氧、好氧和基团化等生物降解方式。在此基础上,提出目前溴代阻燃剂微生物降解研究中存在的主要问题和重点研究方向,并对其在溴代阻燃剂污染治理方面的应用潜力进行展望。
Brominated flame retardants （BFRs） are widely used in plastics, textiles, and electronics for their excellent ability of preventing fires. However, BFRs cause adverse effects on human health and environment for their bioaccumulation, persistence and biotoxicant. Although it is predicted that mi- crobial remediation will bring bright prospect for the purification of BFRs-contaminated environment, less research has been done about the microbial degradation of BFRs. In this paper, we reviewed the recent progresses on microbial degradation of BFRs, including anaerobic degradation, aerobic degradation and other kinds of microbial degradation. In addition, we discussed the problems and challenges in this field, and the future exploitation of the anaerobic debromination.
