多溴联苯醚(PBDEs)作为性能优良的阻燃剂得到了广泛的应用,但是毒理学研究发现,PBDEs具有生殖毒性、免疫毒性、神经毒性和内分泌干扰作用,环境和人体PBDEs暴露水平的增加已引起了越来越多的关注。现有的研究发现,不仅人体血清、母乳及脂肪组织都存在着可检测的PBDEs,而且浓度较30年前呈现出明显的上升趋势,婴儿和儿童的暴露量更是高达成人的数倍。PBDEs的职业暴露多来自于从事电子电器加工及生产的相关工作,而室内灰尘则是儿童暴露的主要来源。
Polybrominated diphenyl ethers (PBDEs) are widely used as excellent flame retardants, but toxicological studies have found that PBDEs have reproductive toxicity, immunotoxicity, neurotoxicity and endocrine disrupting effects. Increases in PBDEs exposure to the environment and humans have caused More and more attention. Existing studies have found that not only detectable levels of PBDEs are present in human serum, breast milk and adipose tissue, but concentrations have been significantly increased from 30 years ago, with infant and child exposures as high as those of adults. Occupational exposure to PBDEs comes mostly from the work involved in the processing and production of electrical and electronic equipment, while indoor dust is the main source of exposure to children.
