为了阐明多溴联苯醚（PBDEs）在全球的分布情况，从世界不同区域（日本、台湾、菲律宾、印度尼西亚、塞舌尔和巴西，以及日本海、东海、南海、印度洋和北太平洋）的近海沃茨采集了鲣鱼（Katsuwonus pelamis）肌肉样品，测定了这些化学物质的含量。在调查地点采集的几乎所有鲣鱼体内都检测到了多溴二苯醚（从< 0.1纳克/克到53纳克/克脂肪），这表明海洋环境中存在这些化合物的广泛污染。这些来自北方半球的样本中多溴二苯醚的残留水平似乎高于来自南半球的样本，这可能是由于这些化合物在北方半球的使用量较大。在中国东海周围沃茨的样本中检测到较高浓度的多溴二苯醚（高达53纳克/克脂质）。东海周边的发展中国家被认为是向海洋环境释放这些化学品的“热点”。关于多溴二苯醚同源物的组成，低溴同源物（BDE 15、BDE 28和BDE 47）所占的百分比随着纬度的增加而呈上升趋势。另一方面，溴化程度较高的同系物（BDE-153、BDE-154和BDE-183）则呈现相反的趋势。这些模式表明，多溴二苯醚的低溴同系物（二溴二苯醚、三溴二苯醚和四溴二苯醚）优先通过大气从污染源迁移到北方较冷的地区。多溴联苯醚可能具有像多氯联苯一样造成全球污染的高效力。
To elucidate the global distribution of polybrominated diphenyl ethers (PBDEs), these chemicals were determined in the muscle of skipjack tuna (Katsuwonus pelamis) collected from offshore waters of various regions in the world (Japan, Taiwan, Philippines, Indonesia, Seychelles, and Brazil, and the Japan Sea, East China Sea, South China Sea, Indian Ocean, and North Pacific Ocean). PBDEs were detected in almost all the skipjack tuna collected from the locations surveyed (from < 0.1 to 53 ng/g of lipid), indicating widespread contamination by these compounds in the marine environment. Residue levels of PBDEs in these samples from the northern hemisphere seem to be higher than those from the southern hemisphere, which is plausibly due to larger usage of these compounds in the northern hemisphere. Higher concentrations of PBDEs were detected in the samples from waters around the East China Sea (up to 53 ng/g of lipid). Developing countries around the East China Sea are supposedly the "hot spots" releasing these chemicals into the marine environment. With regard to the composition of PBDE congeners, the percentage contribution by lower brominated congeners (BDE15, -28, and -47) showed an increasing trend with increasing latitude. On the other hand, higher brominated congeners (BDE153, -154, and -183) showed a reverse trend. These patterns suggest that lower brominated congeners of PBDEs (di-, tri-, and tetra-BDEs) were preferentially transported from pollution sources to northern colder regions through the atmosphere. PBDEs may have a high potency to cause global pollution like PCBs.
