The concentration of mercury in 178 blood samples and 32 hair samples from the Angmagssalik district in East Greenland has been determined. For Greenlanders mercury concentrations are highly dependent on the amount of seal eaten. In the most heavily exposed group (eating more than six meals of seal per week), a significant positive correlation between blood mercury and age was demonstrated. No differences according to sex were demonstrated when the mean values were corrected for influence of age. In the most heavily exposed group, a mean value of 62.5 micrograms Hg/l was found, while in the group eating 1 meal of seal or less per week, the mean value was 22.2 micrograms Hg/l. In the control group consisting of Danes living temporarily in the district, the mean blood mercury concentration was 5.8 corresponding to the fact that they eat seal only occasionally. Hair mercury concentrations were found to correlate well with blood mercury concentrations (r=0.9222). The hair/blood ratio was estimated to 289. It is concluded that the present relatively high mercury exposure in Greenland does not exert any immediate risk of intoxication to the adult population, but supplementary investigation on fetal exposure is needed.
已测定了东格陵兰安马萨克地区178份血液样本和32份头发样本中的汞浓度。对于格陵兰人来说，汞浓度高度依赖于海豹的食用量。在暴露程度最高的组（每周食用超过六餐海豹）中，血液汞含量与年龄之间呈现出显著的正相关。在校正年龄影响后的平均值方面，未显示出性别差异。在暴露程度最高的组中，发现平均值为62.5微克汞/升，而在每周食用1餐或更少海豹的组中，平均值为22.2微克汞/升。在由临时居住在该地区的丹麦人组成的对照组中，血液汞平均浓度为5.8，这与他们只是偶尔食用海豹的情况相符。发现头发汞浓度与血液汞浓度密切相关（r = 0.9222）。头发/血液比率估计为289。得出的结论是，格陵兰目前相对较高的汞暴露对成年人群没有立即造成中毒风险，但需要对胎儿暴露情况进行补充调查。
