由于这些化学品的不利影响，已减少了对传统溴化阻燃剂（BFR）的使用，包括多溴二苯醚（PBDEs）和六溴环十二烷（HBCD）。已经开发了几种新型溴化阻燃剂（NBFR），例如十溴二苯乙烷（DBDPE）和双（2,4,6-三溴苯氧基）乙烷（BTBPE）来代替多溴二苯醚。NBFR用于各种工业和消费产品，导致它们在环境中无处不在。本文回顾了环境中精选的一组NBFR的发生和命运，以及它们对人体的暴露和毒性。两种生物中都存在NBFRs，包括空气，水，灰尘，土壤，沉积物和污泥，以及包括鸟，鱼和人血清在内的生物基质。有关退化的证据，总结了NBFRs的光降解，热降解和生物降解以及生物富集和生物放大。NBFRs的毒性数据表明，几种NBFRs可以通过不同的作用方式引起不良反应，例如激素破坏，内分泌破坏，遗传毒性和行为改变。初步的生态风险评估表明，大多数NBFRs均无明显的环境风险，但值得注意的是，由于毒性数据有限，应谨慎使用该结果。和行为修改。初步的生态风险评估表明，大多数NBFRs均无明显的环境风险，但值得注意的是，由于毒性数据有限，应谨慎使用该结果。和行为修改。初步的生态风险评估表明，大多数NBFRs都没有显着的环境风险，但值得注意的是，由于毒性数据有限，应谨慎使用该结果。

A Review of Environmental Occurrence, Fate, and Toxicity of Novel Brominated Flame Retardants.

Use of legacy brominated flame retardants (BFRs), including polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCD), has been reduced due to adverse effects of these chemicals. Several novel brominated flame retardants (NBFRs), such decabromodiphenyl ethane (DBDPE) and bis(2,4,6-tribromophenoxy) ethane (BTBPE), have been developed as replacements for PBDEs. NBFRs are used in various industrial and consumer products, which leads to their ubiquitous occurrence in the environment. This article reviews occurrence and fate of a select group of NBFRs in the environment, as well as their human exposure and toxicity. Occurrence of NBFRs in both abiotic, including air, water, dust, soil, sediment and sludge, and biotic matrices, including bird, fish, and human serum, have been documented. Evidence regarding the degradation, including photodegradation, thermal degradation and biodegradation, and bioaccumulation and biomagnification of NBFRs is summarized. The toxicity data of NBFRs show that several NBFRs can cause adverse effects through different modes of action, such as hormone disruption, endocrine disruption, genotoxicity, and behavioral modification. The primary ecological risk assessment shows that most NBFRs exert no significant environmental risk, but it is worth noting that the result should be carefully used owing to the limited toxicity data.
