Total mercury (Hg) concentrations were measured in the fur, brain and liver of wild mink (Mustela vison) and river otters (Lontra canadensis) collected from eastern and Atlantic Canada. Total Hg concentrations in fur were strongly correlated with levels in the brain and liver. There was no difference in tissue concentrations between male and female mink; however, female otters had significantly higher fur, brain and liver Hg levels than males. Similarly, there was not a significant relationship between Hg concentration and age of mink, whereas in otters, Hg concentrations in all three tissues decreased significantly with age. In both species, only a very small percentage of the variability in Hg concentration was explained by age. After adjusting the data for site-to-site differences in Hg levels, Hg concentrations in the fur of mink infected by the parasite, Dioctophyma renale, were found to be significantly higher than Hg levels in uninfected mink.
对从加拿大东部和大西洋地区采集的野生水貂（鼬属水貂）和水獭（加拿大水獭）的皮毛、大脑和肝脏中的总汞（Hg）浓度进行了测量。皮毛中的总汞浓度与大脑和肝脏中的水平密切相关。雄性和雌性水貂的组织浓度没有差异；然而，雌性水獭的皮毛、大脑和肝脏中的汞水平明显高于雄性。同样，汞浓度与水貂年龄之间没有显著关系，而在水獭中，所有三种组织中的汞浓度都随着年龄的增长而显著降低。在这两个物种中，年龄对汞浓度变化的解释比例都非常小。在调整了不同地点汞水平差异的数据后，发现感染寄生虫肾膨结线虫的水貂皮毛中的汞浓度显著高于未感染水貂的汞水平。
