摘要:
多溴联苯醚（polybrominated diphenyl ethers，PBDEs）是一类常见的溴代阻燃剂，具有生育毒性、生殖毒性以及致癌性等慢性毒性.作为典型的溴代阻燃剂，多溴联苯醚常被加入到各种产品中以提高产品的安全性，但在各种商业产品的使用过程中，多溴联苯醚会不可避免地逸出至室内环境中，存在于空气或者灰尘中被人体摄入.研究表明，人类一生有80%-90%的时间处于室内环境中，因此，通过了解目前室内环境中多溴联苯醚的污染现状，进而评估通过室内环境暴露多溴联苯醚对人体的潜在危害极为重要.本文总结了室内环境中多溴联苯醚的浓度水平、组成特征以及人体暴露风险，并对未来的研究提出建议.
Abstract:Polybrominated diphenyl ethers (PBDEs) are common brominated flame retardants with chronic toxicity such as fertility toxicity, reproductive toxicity and carcinogenicity. As a typical brominated flame retardant, PBDEs are often added to various products to improve the safety of products. However, in the process of using various commercial products, PBDEs would escape to the indoor environment inevitably and be ingested by human. Studies have shown that human spend 80%-90% of their lifetime indoors. Therefore, it is extremely important to understand the present situation of indoor PBDEs pollution status and to evaluate the harm of indoor PBDEs intake to human health. This paper summarized the concentration level, composition characteristics, main monomers and exposure risk of PBDEs in indoor environment, and offered forward suggestions for future research.
