It is known that the consumption of fish is the main source of mercury intake in human beings. In this study, the concentration of mercury in the muscle tissue of fish from different reservoirs of northwestern Russia was found to be 0.01-1.68 μg/g wet weight. The features of mercury accumulation in the muscle tissue of fish, depending on their type, trophic specialization, body weight, length, and the type of water body, were also revealed. Of the fish studied, 7% had mercury concentrations above the regulatory levels of the Russian Federation. The proportion of examined fish, the consumption of which will lead to an excess of the permissible weekly intake of mercury in the individual, is 44% for preschool children (2-5 years old), 34% for children of primary school age (6-10 years old), and 17% for adults. Special attention is drawn to the fact that the mercury content in fish that does not exceed the sanitary and hygienic standards (normative levels) of the Russian Federation may still be unsafe for the health of the population, especially children.
众所周知，鱼类消费是人类汞摄入的主要来源。在本研究中，俄罗斯西北部不同水库鱼类肌肉组织中的汞浓度为0.01 - 1.68微克/克湿重。还揭示了鱼类肌肉组织中汞积累的特征，这取决于它们的种类、营养专业化程度、体重、体长以及水体类型。在所研究的鱼类中，7%的汞浓度高于俄罗斯联邦的监管水平。对于学龄前儿童（2 - 5岁），食用后会导致个体每周汞摄入量超过允许量的被检查鱼类比例为44%；对于小学年龄儿童（6 - 10岁）为34%；对于成年人则为17%。需要特别注意的是，汞含量未超过俄罗斯联邦卫生和卫生标准（规范水平）的鱼类，对人群尤其是儿童的健康可能仍然不安全。
