The aim of this study was to determine the concentration of mercury (Hg) in liver (L), kidney (K), breast muscle [BM (musculus pectoralis major)], breast feathers (BF), and stomach contents (SC) of mallard (Anas platyrhynchos L. 1758). Among the edible parts of mallard, the greatest concentrations of Hg were observed in K and L, although they did not exceed 1.5 mg/kg dry weight (dw). Average concentrations in K, L, and BM were 0.27, 0.25, and 0.13 mg/kg dw, respectively. Significant correlations were observed between Hg concentrations in BM and K and in BM and L (r s = 0.92) as well as between Hg concentrations in these tissues and BF. In addition, we found significant correlations between Hg concentrations in SC and BM (r s = 0.72) and in L and K (r s = 0.55). In conclusion, mallard exhibits a measurable response to environmental Hg pollution and meets the requirements of a bioindicator.
本研究旨在测定鸭（Anas platyrhynchos L. 1758）肝脏（L）、肾脏（K）、胸肌[BM（胸大肌）]、胸羽（BF）和胃内容物（SC）中的汞（Hg）浓度。在鸭的可食用部分中，Hg 浓度最高的是 K 和 L，但均未超过 1.5 毫克/公斤干重（dw）。K、L 和 BM 中的平均浓度分别为 0.27、0.25 和 0.13 毫克/公斤 dw。BM 与 K 以及 BM 与 L 中的 Hg 浓度之间存在显著相关性（r s = 0.92），并且这些组织与 BF 中的 Hg 浓度之间也存在显著相关性。此外，我们发现 SC 与 BM（r s = 0.72）以及 L 和 K（r s = 0.55）之间的 Hg 浓度存在显著相关性。综上所述，鸭对环境 Hg 污染表现出可测量的反应，符合生物指示剂的要求。
