Total mercury concentration in hair, sampled at delivery, was determined in women living in an area polluted with atmospheric emissions of mercury from a metal smelter, (n = 122) and in a control area (n = 75). Information on fish consumption was obtained at the 10th week of pregnancy. The average mercury concentration in hair was 0.27 mg/kg (range 0.07-0.96 mg/kg), which is somewhat lower than previously reported for pregnant women in Sweden and very low compared with levels in fish-eating populations in other parts of the world. Women living in the polluted area had significantly lower mercury levels in hair than women in the control area when comparing groups with quantitatively similar consumption of freshwater fish. Possibly, the population in the smelter area does not catch fish in the neighbourhood and/or the fish in the control area has elevated mercury levels. Consumption of freshwater fish > or = once a week resulted in approximately twice as high hair mercury levels as in those who did not eat freshwater fish at all. Also consumption of saltwater fish > or = once a week resulted in significantly higher hair mercury levels than in those consuming saltwater fish < once a month. Hair levels from the 10th week of pregnancy were similar to the levels at delivery in women with high (> or = once a week) consumption of freshwater fish but decreased during this period in women who did not eat freshwater fish at all, which could be explained by decreased exposure during pregnancy and measurement in recently formed hair.
对居住在受金属冶炼厂汞大气排放污染地区的122名妇女以及对照地区的75名妇女，测定了分娩时采集的头发中的总汞浓度。在怀孕第10周获取了鱼类消费信息。头发中的平均汞浓度为0.27毫克/千克（范围为0.07 - 0.96毫克/千克），这略低于瑞典此前报告的孕妇汞浓度，与世界其他地区食鱼人群的汞浓度相比非常低。在比较淡水鱼消费量定量相似的组时，居住在污染地区的妇女头发中的汞含量显著低于对照地区的妇女。可能是冶炼厂地区的人群不在附近捕鱼和/或对照地区的鱼汞含量升高。每周食用淡水鱼≥一次的妇女头发中的汞含量大约是完全不食用淡水鱼的妇女的两倍。每周食用咸水鱼≥一次的妇女头发中的汞含量也显著高于每月食用咸水鱼＜一次的妇女。怀孕第10周时头发中的汞含量与每周食用淡水鱼量高（≥一次）的妇女分娩时的汞含量相似，但在完全不食用淡水鱼的妇女中，这一期间汞含量下降，这可以用怀孕期间接触减少以及对新长出头发进行测量来解释。
