In terms of reproductive and other adverse outcomes after exposure to polychlorinated biphenyls (PCBs), dioxins, and furans, the mink (Mustela vison) is one of the most sensitive mammals. Our objective was to determine if there are differences in the concentrations of total mercury (Hg), total PCBs, and dioxin-furan toxic equivalents (TEQs) between mink living in and out of the Rochester Embayment of Lake Ontario (RELO) Area of Concern (AOC) and between mink living near the shore of Lake Ontario and inland. Concentrations of total Hg in the brain, total PCBs and dioxin-furan TEQs in adipose, and total PCBs in liver were significantly higher for mink living near the shore of Lake Ontario than inland. For mink living in and out of the AOC, differences in total PCBs and dioxin-furan TEQs in adipose and the liver were substantial but not significant. Correlations among concentrations of total Hg, total PCBs, and dioxin-furan TEQs in mink were high. Our results suggest that contamination of mink living near the southern shore of Lake Ontario primarily comes from contact with the Lake Ontario food web, not from sources in the RELO AOC.
就接触多氯联苯（PCBs）、二恶英和呋喃后产生的生殖和其他不良后果而言，水貂（Mustela vison）是最敏感的哺乳动物之一。我们的目的是确定生活在安大略湖北罗彻斯特港湾（RELO）关注区域（AOC）内外的水貂，以及生活在安大略湖岸边和内陆的水貂之间，其体内总汞（Hg）、总 PCBs 和二恶英呋喃毒性当量（TEQs）的浓度是否存在差异。生活在安大略湖岸边的水貂的大脑中总汞、脂肪中二恶英呋喃 TEQs 和肝脏中总 PCBs 的浓度明显高于内陆地区。对于生活在 AOC 内外的水貂，脂肪和肝脏中总 PCBs 和二恶英呋喃 TEQs 的差异虽然很大，但并不显著。水貂体内总 Hg、总 PCBs 和二恶英呋喃 TEQs 的浓度之间存在高度相关性。我们的结果表明，生活在安大略湖南岸附近的水貂的污染主要来自与安大略湖食物网的接触，而不是来自 RELO AOC 的来源。
