Levels of mercury, methylmercuri and selenium were determined in liver samples from wild mink (Mustela vision) caught in the Norwegian countries of Rogaland (38 samples), Sogn og Fjordane (15 samples) and Hedmark (18 samples). The average mercury levels from these counties were 2.6, 3.1 and 2.1 micrograms Hg/g wet weight, respectively. No significant differences in mercury levels were found. The methyl mercury levels (MeHg) were determined in 30 samples. A very strong positive correlation between total mercury (Hg) and methyl mercury (r = 0.91, P less than 0.001) was found. The average methyl mercury level was 35 per cent of total mercury. This indicates that wild mink has the ability to demethylate mercury. The selenium levels were determined in 35 samples. A strong positive correlation between the levels of total mercury and selenium (r = 0.87, P less than 0.001) was found. There was no correlation between age or nutritional condition and mercury level. In the present study mink was examined to see of it could be recommended as an indicator species for monitoring the local environment for mercury contamination. No definite answer to this question could be found. The study did reveal, however, that in all the counties studied there are individuals that are considerably contaminated with mercury.
对在挪威罗加兰郡（38个样本）、松恩-菲尤拉讷郡（15个样本）和海德马克郡（18个样本）捕获的野生水貂（鼬属）肝脏样本中的汞、甲基汞和硒含量进行了测定。这些郡的汞平均含量分别为2.6、3.1和2.1微克汞/克湿重。未发现汞含量有显著差异。对30个样本测定了甲基汞含量（MeHg）。发现总汞（Hg）与甲基汞之间存在非常强的正相关（r = 0.91，P小于0.001）。甲基汞平均含量占总汞的35%。这表明野生水貂具有使汞脱甲基的能力。对35个样本测定了硒含量。发现总汞含量与硒含量之间存在强正相关（r = 0.87，P小于0.001）。年龄或营养状况与汞含量之间无相关性。在本研究中，对水貂进行了检查，以确定是否可将其推荐为监测当地环境汞污染的指示物种。未找到关于这个问题的确切答案。然而，该研究确实表明，在所有研究的郡中，都有个体受到汞的严重污染。
