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 dry weight (dw), respectively. Se concentrations were higher in the hair of raccoons than of wildcats (0.851 and 0.641 mg kg 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.
本研究检测了陆生动物毛发样本中的总汞（THg）和硒（Se）浓度，以及Se:THg的摩尔比。对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THg和Se浓度进行了测量。浣熊和野猫毛发中的THg浓度中位数分别为0.369和0.273毫克/千克干重（dw）。浣熊毛发中的Se浓度高于野猫（分别为0.851和0.641毫克/千克dw）。卢森堡浣熊毛发中的总汞浓度几乎比德国浣熊毛发中的高5倍；然而，Se浓度相似。因此，德国浣熊毛发中的Se:THg摩尔比约为卢森堡浣熊的4倍。在野猫和浣熊中，均发现THg浓度与Se:THg摩尔比之间存在显著的负相关。
