摘要
溴代二噁英类化合物是一类剧毒环境污染物,主要来源于溴系阻燃剂与含溴系阻燃剂聚合物的生产、使用和回收等过程。随着溴系阻燃剂的广泛使用,溴代二噁英类化合物的环境和健康风险日益增加,对其环境问题的研究已成为当今环境科学的一大热点,而中国在此方面的研究还相当薄弱。介绍了溴代二噁英类化合物的结构性质,综述了溴代二噁英类化合物的分析方法、污染来源和环境分布,重点探讨了溴代二噁英类化合物的生成机制,介绍了生成溴代二噁英类化合物的影响因素,讨论并总结了当前研究中溴代二噁英类化合物污染来源解析与生成机制所存在的问题,最后展望了未来溴代二噁英类化合物的环境研究趋势。
Polybrominated dibenzo-p-dioxins and dibenzofurans （PBDD/Fs） are important toxic organic contaminants released from the application, manufacturing, and recycling of brominated flame retardants. The environment and health risks of the persistent PBDD/Fs will continue to increase because of the wide usages of brominated flame retardants. Although the environmental problems of PBDD/Fs have been well recognized, there are yet only few studies of PBDD/Fs reported in the Chinese literature. The paper presented the results of a literature review on recent environmental research in structure and properties, analytical methods, sources/origins, formation mechanism, yield and distribution of PBDD/Fs. It also summarized some problems of the source analyses and formation mechanisms and forecasts several directions of future research of PBDD/Fs.
