Abstract

Results are reported of a pilot survey of concentrations of polybrominated diphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) in shark liver oil supplements. Eleven brands of dietary supplements were analysed using an isotope dilution GC/MS method. Total concentrations of 10 PBDE congeners (BDE-28, -47, -49, -66, -99, -100, -153, -154, -155 and -183) ranged from 0.1 to 53 ng g-1 oil weight and total concentrations of six PCB congeners (CB-28/31, -52, -118, -153 and -180) in the samples ranged from 16 to 340 ng g-1 oil weight (undetected values are not included). Two brands of Japanese deep-sea shark liver oil contained the highest levels of PBDEs (49-53 ng g-1 oil weight) and PCBs (290-340 ng g-1 oil weight). These results indicate that PBDEs may have entered Japanese deep-sea waters.

摘要

本文报告了一项关于鲨鱼肝油补充剂中多溴二苯醚（PBDEs）和多氯联苯（PCBs）浓度的初步调查结果。使用同位素稀释气相色谱/质谱法对11个品牌的膳食补充剂进行了分析。10种PBDE同系物（BDE-28、-47、-49、-66、-99、-100、-153、-154、-155和-183）的总浓度范围为0.1至53纳克/克油重，样品中6种PCB同系物（CB-28/31、-52、-118、-153和-180）的总浓度范围为16至340纳克/克油重（未检测到的值未包括在内）。两个品牌的日本深海鲨鱼肝油中PBDEs（49 - 53纳克/克油重）和PCBs（290 - 340纳克/克油重）含量最高。这些结果表明PBDEs可能已进入日本深海海域。
