近些年来,环境中的溴代有机污染物逐渐成为人们关注的热点。最近的研究发现,海洋环境中的一些溴代有机物并非来自于人为污染,而是来自于天然合成。海洋环境中存在的这些天然溴代有机物引起了人们极大的兴趣。这些天然溴代有机物在海洋生物、底泥、海水以及大气中广泛存在,并可在海洋哺乳动物体内富集。毒理学研究表明,一些天然溴代有机物具有一定的生物活性与毒性。因此,深入研究天然溴代有机物的环境分布与环境影响具有重要的意义。本文介绍了代表性天然溴代有机物的环境分布、毒性及其可能的来源,并对其未来研究方向和趋势作了展望。
In recent years, brominated organic pollutants in the environment have gradually become the focus of attention. Recent studies have found that some of the brominated organic compounds in the marine environment do not originate from anthropogenic pollution but come from natural synthesis. These natural brominated organics present in the marine environment are of great interest. These natural brominated organic compounds are widespread in marine organisms, sediments, seawater and the atmosphere and can be enriched in marine mammals. Toxicology studies have shown that some natural brominated organic compounds have certain biological activity and toxicity. Therefore, it is of great significance to deeply study the environmental distribution and environmental impact of natural brominated organic compounds. This paper introduces the environmental distribution, toxicity and possible sources of representative natural brominated organic compounds, and prospects the future research directions and trends.
