近年来,多溴联苯醚的结构类似物羟基和甲氧基多溴联苯醚逐渐成为人们研究的热点。它们广泛分布在海水、沉积物和海洋生物中,并能在哺乳动物体内累积。由于结构与多溴联苯醚类似,羟基和甲氧基多溴联苯醚也具有相似的生物活性和毒性。研究表明,海洋环境中这类化合物可能源于天然合成,而不是人为污染物的直接排放或者降解。开展这两类天然溴代有机化合物的环境行为研究具有十分重要的现实意义。本文综述了海洋环境中羟基和甲氧基多溴联苯醚来源与分布的研究现状,同时对未来的研究方向进行了展望。

In recent years, the structural analogs of polybrominated diphenylethers and hydroxy polybrominated diphenyl ethers have gradually become the focus of research. They are widely distributed in seawater, sediments and marine life and accumulate in mammals. Similar to PBDEs, hydroxyl and methoxy polybrominated diphenyl ethers also have similar bioactivity and toxicity. Studies have shown that such compounds in the marine environment may be derived from natural synthesis, rather than the direct discharge or degradation of anthropogenic pollutants. It is of great practical significance to carry out the research on the environmental behavior of these two types of natural brominated organic compounds. This review summarizes the current research status of the sources and distribution of hydroxyl and methoxy polybrominated diphenyl ethers in the marine environment. In addition, the future research directions are prospected.
