摘要:十溴二苯乙烷（DBDPE）和1,2?双（2,4,6?三溴苯氧基）乙烷（BTBPE）作为新型溴系阻燃剂，因具有亲脂性和持久性而易于在环境介质中累积。总结了DBDPE和BTBPE在生物和非生物环境介质中的分布特征。DBDPE和BTBPE易与固相紧密结合，土壤、污泥和粉尘中的浓度远高于其他环境介质中。DBDPE和BTBPE在生物中的分布与生物种类、器官组织等有一定关系，并且在人体母乳、血液和头发中也有检出。商业化DBDPE和BTBPE的生产和使用以及电子垃圾拆解活动是DBDPE和BTBPE在环境中的主要来源。未来需对DBDPE和BTBPE在不同环境介质中的迁移转化行为、生物效应的分子机制进一步展开研究。



Abstract:Decabromodiphenyl ethane (DBDPE) and 1,2-bis(2,4,6 tribromophenoxy) ethane (BTBPE), as novel brominated flame retardants, are liable to accumulate in the environmental matrices due to their persistence and lipophilic characteristics. The distribution characteristics of DBDPE and BTBPE in biological and abiotic environmental matrices are reviewed. DBDPE and BTBPE combine easily with solid phase, therefore, their concentration in soil, sludge and indoor dust is much higher than other environmental media. The distribution characteristics of DBDPE and BTBPE in biological matrices are related with biological species, tissues, organs， etc. Moreover, DBDPE and BTBPE were also found in human breast milk, blood and hair. The production and the use of commercial DBDPE and BTBPE, as well as e-waste recycling activities are their main sources in the environment. It is necessary to further explore the transport and transformation behavior of DBDPE and BTBPE in different environmental matrices, and the molecular mechanism of biological effects.
