摘　　要：为了分析两种典型溴代阻燃剂十溴二苯醚(Decabromodiphenyl Ether,简称DBDE)和六溴环十二烷(Hexabromocyclododecane,简称HBCD)的环境影响,基于生命周期评价方法构建,在深圳市相关企业调研数据基础上,分析了DBDE和HBCD在使用、加工及处理过程中的使用配比、能耗情况,整理出DBDE和HBCD对环境排放的清单;同时,评价了DBDE和HBCD对环境产生的各种影响,提出了各阶段污染控制的主要环节。结果表明:DBDE和HBCD对环境的影响大小依次为全球变暖>酸化>烟尘&粉尘>富营养化>臭氧耗竭>光化学氧化,对全球变暖、酸化和烟尘&粉尘影响贡献分别为50.47%、34.60%、7.00%;污染主要来源于DBDE和HBCD的挤出及注塑阶段。This study was focused on the analysis of the environmental impacts of two typical brominated flame retardants:Decabromodiphenyl Ether(DBDE)and Hexabromocyclododecane(HBCD)in Shenzhen.Based on the life cycle assessment method and the survey data of relevant enterprises,the proportion and energy consumption of DBDE and HBCD in the process of use,processing and treatment were analyzed.The list of environmental emissions from DBDE and HBCD was then compiled.At the same time,the various impacts of DBDE and HBCD on the environment were evaluated.And the main links of pollution control at each stage were proposed.The results showed that the impacts of DBDE and HBCD on the environment were in the order of global warming>acidification>smoke&dust>eutrophication>ozone depletion>photochemical oxidation;their contributions to global warming,acidification and smoke&dust were 50.47%,34.60%and 7.00%respectively.In additon,the pollution mainly came from the extrusion and injection stages of DBDE and HBCD.
