Fish oil supplements have become a popular means of increasing one's dietary intake of essential polyunsaturated fatty acids. However, there is growing concern that the levels and potential health effects of lipophilic organic contaminants such as polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) may diminish some of the health benefits associated with the daily consumption of fish oil supplements. In this study, ten over-the-counter fish oil supplements available in the United States were analysed for PCBs and PBDEs and daily exposures calculated. Based on manufacturers' recommended dosages, daily intakes of PCBs and PBDEs ranged from 5 to 686 ng day(-1) and from 1 to 13 ng day(-1), respectively. Daily consumption of fish oil supplements expose consumers to PCBs and PBDEs. However, in comparison with fish ingestion, fish supplements may decrease daily PCB exposure and provide a safer pathway for individuals seeking to maintain daily recommended levels of polyunsaturated fatty acids.
鱼油补充剂已成为增加饮食中必需多不饱和脂肪酸摄入量的一种流行方式。然而，人们越来越担心脂溶性有机污染物（如多氯联苯（PCBs）和多溴二苯醚（PBDEs））的水平和潜在健康影响可能会降低与每天食用鱼油补充剂相关的一些健康益处。在这项研究中，对美国市场上的十种非处方鱼油补充剂进行了 PCBs 和 PBDEs 的分析，并计算了每日暴露量。根据制造商推荐的剂量，每日摄入的 PCBs 和 PBDEs 范围分别为 5 至 686ng/天和 1 至 13ng/天。每日食用鱼油补充剂会使消费者接触到 PCBs 和 PBDEs。然而，与鱼类摄入相比，鱼类补充剂可能会降低每日 PCB 暴露量，并为那些希望维持每日推荐的多不饱和脂肪酸水平的个体提供更安全的途径。
