摘　　要：多溴联苯醚是一类溴代阻燃剂,包括三种主要的工业产品,五溴、八溴、十溴联苯醚。该物质曾广泛使用于电子、材料、家具等产品中。研究表明,在这些产品的生产、使用和处理过程中均会释放多溴联苯醚到周边环境中。多溴联苯醚具有持久性、可生物富集和长距离迁移,对人体和身体系统存在潜在危害,是一类新兴污染物。目前,这类物质中的部分化合物已被《斯德哥尔摩公约》禁止生产和使用。一方面,人类曾使用的多溴联苯醚会通过工业废水和生活污水的排放汇集于污水和污泥,继而又成为环境介质中多溴联苯醚的重要来源。文章系统综述了国内外污水和污泥中多溴联苯醚的污染浓度水平、同系物分布特征和环境效应,为进一步开发污水处理中多溴联苯醚的去除技术和制定污水和污泥中多溴联苯醚的控制标准奠定了基础。Polybrominated diphenyl ethers（PBDEs） are one group of flame retardants,including 3 major commercial products such as penta-,octa-and deca-BDE.PBDEs were widely used in electrical,material and furniture products.The previous studies showed that PBDEs can be released to the surroundings during the production,usage and disposal process of the products containing PBDEs.As emerging pollutants,PBDEs which are relatively persistent with potential for long range transport and bioaccumulation in biota have potential toxicity to ecosystem and human beings,thus some compounds of PBDEs were banned by the Stockholm Convention.PBDEs discharged by human activity before can gather in wastewater and sewage sludge,and then entered into environmental media by disposal of wastewater and sewage sludge.The concentrations,distribution and environmental effects of PBDEs were reviewed in order to provide the basis for developing treatment technology and making control standards for PBDEs in wastewater and sewage sludge.
