This study examined the concentration of total mercury (THg) and selenium (Se), as well as the molar ratio of Se:THg in hair samples of terrestrial animals. THg and Se concentrations were measured from the hair of raccoons (Procyon lotor) and European wildcats (Felis s. silvestris) from Germany and Luxembourg. Median THg concentrations in hair from raccoons and wildcats were 0.369 and 0.273 mg kg-1 dry weight (dw), respectively. Se concentrations were higher in the hair of raccoons than of wildcats (0.851 and 0.641 mg kg-1 dw, respectively). Total mercury concentration in hair of raccoons from Luxembourg was almost 5× higher that found in hair of raccoons from Germany; however, Se concentration was similar. Thus, molar ratio of Se:THg was ~4× higher in the hair of raccoons from Germany than those from Luxembourg. Significant negative correlation was found between THg concentration and Se:THg molar ratio in both wildcats and raccoons.

来自德国和卢森堡的浣熊（Procyon lotor）和欧洲野猫（Felis s. silvestris）毛发中的硒和汞。


本研究检测了陆生动物毛发样本中总汞 (THg) 和硒 (Se) 的浓度，以及 Se:THg 的摩尔比。 THg 和 Se 浓度是从德国和卢森堡的浣熊 (Procyon lotor) 和欧洲野猫 (Felis s. silvestris) 的毛发中测量的。浣熊和野猫毛发中 THg 的中位浓度分别为 0.369 和 0.273 mg kg-1 干重 (dw)。浣熊毛发中的硒浓度高于野猫（分别为 0.851 和 0.641 mg kg-1 dw）。卢森堡浣熊毛发中的总汞浓度几乎是德国浣熊毛发中的总汞浓度的 5 倍；然而，Se 浓度相似。因此，德国浣熊毛发中 Se:THg 的摩尔比比卢森堡浣熊的毛发高约 4 倍。在野猫和浣熊中，THg 浓度与 Se:THg 摩尔比之间存在显着负相关。
