Data on distribution, concentration and trends of polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecanes (HBCDs) is scarce in biota from the sub-Arctic region of the Atlantic. The present study is an investigation on PBDE and HBCD concentrations in eggs from seven marine bird species from Iceland, i.e. common eider (Somateria mollissima), arctic tern (Sterna paradisaea), guillemot (Uria aalge), fulmar (Fulmarus glacialis), lesser black-backed gull (Larus fuscus), great black-backed gull (Larus marinus) and great skua (Stercorarius skua). Concentrations of sum PBDEs ranged from 44 ng g(-1)fat in eider eggs to 2400 ng g(-1)fat in great skua eggs. The contribution of different PBDE congeners to the sum concentration differed between species. Concentration of HBCDs (sum of α-,β(-) and γ-HBCD) ranged from 1.3 ng g(-1)fat in arctic tern eggs to 41 ng g(-1)fat in great black-backed gull. PCA on PBDE and HBCD shows different trends between the two BFR groups, further indicating different sources/usage. Investigations on any potential health or population effects of environmental pollutants on the great skua are advised since both the PBDE and HBCD concentrations are high.
多溴二苯醚（PBDEs）和六溴环十二烷（HBCDs）在北大西洋亚北极地区生物群中的分布、浓度和趋势数据稀缺。本研究调查了冰岛 7 种海鸟（普通绒鸭（Somateria mollissima）、北极燕鸥（Sterna paradisaea）、海鸠（Uria aalge）、管鼻鹱（Fulmarus glacialis）、黑背鸥（Larus fuscus）、大黑背鸥（Larus marinus）和大贼鸥（Stercorarius skua））的鸡蛋中 PBDE 和 HBCD 的浓度。PBDE 总量的浓度范围从绒鸭蛋中的 44ng/g 脂肪到大贼鸥蛋中的 2400ng/g 脂肪。不同 PBDE 同系物对总浓度的贡献在不同物种之间存在差异。HBCDs（α-、β(-)和γ-HBCD 的总和）浓度范围从北极燕鸥蛋中的 1.3ng/g 脂肪到黑背鸥蛋中的 41ng/g 脂肪。PBDE 和 HBCD 的 PCA 显示了两组阻燃剂之间的不同趋势，进一步表明了不同的来源/用途。建议对大贼鸥的环境污染物对健康或种群的任何潜在影响进行调查，因为 PBDE 和 HBCD 的浓度都很高。
