Mercury and selenium in whole blood and serum of 245 17-year old Swedish adolescents were analysed. The relationships between these elements' concentrations and the consumption of fish as well as the number of dental amalgam fillings were studied. The geometric means (GM) of the mercury concentrations were 1.1 microg/L in blood and 0.43 microg/L in serum. The mean selenium concentration in blood was 110 microg/L and the GM of the serum selenium concentration 110 microg/L. Fish species with dietary restrictions due to elevated mercury Levels (i.e. pike, perch, pikeperch, burbot, eel and halibut) were consumed on average 0.7 times/month and fish species without such restrictions 4.1 times/month. Despite this comparatively low fish consumption, the adolescents' blood mercury concentrations were positively correlated with fish consumption. Of the adolescents, 39% had amalgam fillings (mean 2 +/- 1.5). Serum mercury was influenced by the number of amalgam fillings, by fish consumption, blood and serum levels of selenium and the residential area. Blood and serum selenium concentrations were not influenced by fish consumption, but were positively associated with the serum mercury concentration.
对245名17岁瑞典青少年全血和血清中的汞和硒进行了分析。研究了这些元素浓度与鱼类消费量以及牙科汞合金填充物数量之间的关系。血液中汞浓度的几何平均值（GM）为1.1微克/升，血清中为0.43微克/升。血液中硒的平均浓度为110微克/升，血清硒浓度的几何平均值为110微克/升。因汞含量升高而有饮食限制的鱼类（即梭子鱼、鲈鱼、梭鲈、江鳕、鳗鱼和大比目鱼）平均每月食用0.7次，无此类限制的鱼类平均每月食用4.1次。尽管鱼类消费量相对较低，但青少年的血液汞浓度与鱼类消费量呈正相关。在青少年中，39%有汞合金填充物（平均2±1.5个）。血清汞受汞合金填充物数量、鱼类消费量、血液和血清硒水平以及居住地区的影响。血液和血清硒浓度不受鱼类消费量的影响，但与血清汞浓度呈正相关。
