The consumption of fish in food may contain mercury, a harmful element and dangerous chemical detrimental to human health. The purpose of this study was to determine the mercury level in the hair of pregnant women with different fish intakes in their diets. The concentration of total mercury in hair was determined using an atomic absorption spectrometer. In this study, 98 pregnant women were invited to participate (aged from 18 to 48 years). The mean content of mercury in the hair of pregnant women in Northwestern Russia was 0.428 mg/kg (ranging from 0.018 to 3.1 mg/kg). As a result, 22% of women had mercury values above 0.58 mg/kg, which is considered dangerous for the fetus. The hair mercury concentration in a village area was higher than that in a city area (i.e., 0.548 mg/kg and 0.326 mg/kg). Moreover, the maximum level of mercury was noted for a group of pregnant women who consumed more than 5 kg/month of fish and fish products. Furthermore, the consumption of freshwater fish in the diet leads to a higher mercury content in the hair of pregnant women than the consumption of marine fish.
食物中的鱼类可能含有汞，汞是一种对人体健康有害的元素和危险化学品。本研究的目的是确定饮食中鱼类摄入量不同的孕妇头发中的汞含量。使用原子吸收光谱仪测定头发中总汞的浓度。在本研究中，邀请了98名孕妇参与（年龄在18至48岁之间）。俄罗斯西北部孕妇头发中的汞平均含量为0.428毫克/千克（范围为0.018至3.1毫克/千克）。结果，22%的女性汞值高于0.58毫克/千克，这对胎儿来说被认为是危险的。农村地区孕妇头发中的汞浓度高于城市地区（分别为0.548毫克/千克和0.326毫克/千克）。此外，每月食用超过5千克鱼类和鱼产品的孕妇群体汞含量最高。此外，饮食中食用淡水鱼导致孕妇头发中的汞含量高于食用海鱼。
