The geographical distribution of hexabromocyclododecane (HBCD) was investigated through analysis of muscle tissue of skipjack tuna (Katsuwonus pelamis) collected from offshore waters of Asia-Pacific region (Japan, Taiwan, Philippines, Indonesia, Seychelles, Brazil, Japan Sea, East China Sea, South China Sea, Indian Ocean and North Pacific Ocean). HBCD was detected in almost all samples analyzed (<0.1 to 45 ng/g lipid weight basis), indicating widespread presence of this compound in the marine environment. Elevated concentrations of HBCD were found in skipjack tuna from areas around Japan, which have the larger modern industrial/urban societies, and implicated these areas as primary regional sources. All three individual HBCD isomers (alpha-, gamma- and beta-HBCD) were detected in almost all samples; the percentage contribution of the alpha-isomer to total HBCD increased with increasing latitude. The estimated empirical 1/2 distance for alpha-HBCD was 8500 km, which is one of the highest atmospheric transportability among various halogenated persistent organic pollutants (POPs).
通过对从亚太地区（日本、台湾、菲律宾、印度尼西亚、塞舌尔、巴西、日本海、东海、南海、印度洋和北太平洋）近海采集的鲣鱼（Katsuwonus pelamis）肌肉组织进行分析，研究了六溴环十二烷（HBCD）的地理分布。在几乎所有分析的样本中都检测到了HBCD（基于脂质重量，含量为<0.1至45纳克/克），这表明该化合物在海洋环境中广泛存在。在来自日本周边地区的鲣鱼中发现了较高浓度的HBCD，这些地区有较大规模的现代工业/城市社会，并认为这些地区是主要的区域来源。几乎在所有样本中都检测到了所有三种HBCD异构体（α-、γ-和β-HBCD）；α-异构体在总HBCD中的贡献百分比随纬度增加而增加。α-HBCD的估计经验半程距离为8500公里，这是各种卤代持久性有机污染物（POPs）中大气传输能力最高的之一。
