数十年来，溴化阻燃剂（BFR）已常规用作许多消费品的添加剂，以降低发生火灾的风险。由于这些物质可能的毒性，内分泌干扰特性以及在几乎所有环境区域（包括人类和野生生物）中的发生，对这些物质大量使用的担忧有所增加。几种传统的溴化阻燃剂（例如多溴二苯醚（PBDE））已被列入持久性有机污染物清单，由于其确定的毒性和对环境的持久性，其使用受到限制。在过去的几年中，这些化合物已被“新的” BFR（NBFR）取代。尽管NBFR是与传统BFR不同的化学分子，两组的大多数物理化学性质（例如芳族部分，卤素取代，亲脂性）都是相同的；因此，它们在环境中的命运可能与被禁止的BFR类似。因此，本文的目的是总结有关最广泛使用的NBFRs的生物降解性的科学数据，NBFRs是其在环境中的潜在持久性的关键因素，以及它们对人和测试生物的生态毒理作用。此处审查的数据表明，通过NBFR释放的机制超出了其生态毒性，并且导致它们在环境中发生生物转化的过程仍知之甚少。因此，重点是在这些领域进行进一步研究的需要，因此，

Ecotoxicity and biodegradability of new brominated flame retardants: a review.

Brominated flame retardants (BFRs) have been routinely used as additives in a number of consumer products for several decades in order to reduce the risk of fire accidents. Concerns about the massive use of these substances have increased due to their possible toxicity, endocrine disrupting properties and occurrence in almost all the environmental compartments, including humans and wildlife organisms. Several conventional BFRs (e.g. polybrominated diphenylethers (PBDE)) have been included in the list of Persistent Organic Pollutants and their use has been restricted because of their established toxicity and environmental persistence. Over the past few years, these compounds have been replaced with "new" BFRs (NBFRs). Despite the fact that NBFRs are different chemical molecules than traditional BFRs, most of physical-chemical properties (e.g. aromatic moiety, halogen substitution, lipophilic character) are common to both groups; therefore, their fate in the environment is potentially similar to the banned BFRs. Therefore, this article has been compiled to summarize the published scientific data regarding the biodegradability of the most widely used NBFRs, a key factor in their potential persistency in the environment, and their ecotoxicological effects on humans and test organisms. The data reviewed here document that the mechanisms through NBFRs exibit their ecotoxicity and the processes leading to their biotransformation in the environment are still poorly understood. Thus emphasis is placed on the need for further research in these areas is therefore emphasized, in order to avoid the massive use of further potentially harmful and recalcitrant substances of anthropogenic origin.
