Polybrominated diphenyl ethers (PBDEs) are known brominated flame retardants that have now been banned or phased out in many parts of the world. As a consequence, interest in the environmental occurrence of non-PBDE flame retardants has increased. In the present study several potential PBDE replacement products together with short chained chlorinated paraffins (SCCPs) were assessed in Greenland sharks accidentally caught in waters around Iceland between 2001 and 2003. Non-PBDE flame retardants detected were pentabromoethylbenzene (PBEB), 1,2-bis(2,4,6-tribromophenoxy)ethane (BTBPE) and 2,3,5,6-tetrabromo-p-xylene (TBX). The concentrations were lower than levels of BDE-47 but similar to other PBDE congeners previously reported in Greenland shark. The median concentrations of SCCPs was 430 ng g(-1) fat, similar to individual PCB congeners previously reported. This is the first report of SCCPs, BTBPE, PBEB and TBX in any shark species globally and confirms the usefulness of the Greenland shark as a screening species for environmental contamination in the Arctic and sub-Arctic environment.
多溴二苯醚（PBDEs）是一种已知的溴化阻燃剂，现已在世界许多地区被禁止或逐步淘汰。因此，人们对环境中存在的非 PBDE 阻燃剂的兴趣日益增加。本研究评估了在 2001 年至 2003 年间冰岛附近海域意外捕获的格陵兰鲨鱼体内的几种潜在的 PBDE 替代品和短链氯化石蜡（SCCPs）。检测到的非 PBDE 阻燃剂为五溴乙基苯（PBEB）、1,2-双（2,4,6-三溴苯氧基）乙烷（BTBPE）和 2,3,5,6-四溴对二甲苯（TBX）。这些浓度低于 BDE-47 的水平，但与之前在格陵兰鲨鱼中报告的其他 PBDE 同系物相似。SCCPs 的中位数浓度为 430ng/g 脂肪，与之前报告的个别 PCB 同系物相似。这是首次在任何鲨鱼物种中报告 SCCPs、BTBPE、PBEB 和 TBX，证实了格陵兰鲨鱼作为北极和亚北极环境中环境污染筛选物种的有用性。
