Проведен количественный анализ Hg в волосах условно здоровых детей (n=62), верхнем слое собранной на территории бывшего Целлюлозно-картонного комбината одного из городов Хабаровского края почвы (n=15) и в обитающей в нижнем течении реки Амур рыбе (n=27) методом масс-спектрометрии с индуктивно связанной плазмой. Исследована связь уровня ртути и когнитивных способностей детей.Результаты. Среднее содержание Hg в верхнем слое почвы составило 0,85 мг/кг с максимальным значением массовой доли 1,25 мг/кг, что в 8,5 – 12,5 раз выше российского фонового значения. При определении концентрации Hg в мышечной ткани рыб – основного источника органической Hg для детей – установлено, что содержание Hg в тканях хищных рыб колебалось в пределах 0,47 – 0,52 мг/кг, при этом уровень Hg в нехищной рыбе составлял 0,24 мг/кг. Среднее содержание Hg в волосах у подростков составило 0,47±0,05 мг/кг и 0,19±0,02 мг/кг у детей 6 – 7 лет, что не превышает критического уровня.Заключение. Содержание Hg в почве существенно снизилось в сравнении с исследованиями 2009 года, но уровень сохраняется выше российского фонового значения. Содержание ртути в мышечной части рыбы, выловленной в нижнем течении реки Амур, было выше у хищных пород. В организме детей, постоянно проживающих на территории антропогенного загрязнения Hg, ее концентрация не превышала пороговый уровень, однако выявленные фоновые значения, возможно, способствовали снижению концентрации внимания.</p></abstract><trans-abstract xml:lang="en"><p>Study Objective: to determine the mercury content in the body of children as well as in soil and river fish to assess the level of risk of adverse effects on a human body.Study Design: analytical observational, cross-sectional study.Materials and Methods. A quantitative analysis of mercury in hair of conditionally healthy children (n=62), the upper layer of soil (n=15) taken on the territory of the former cellulose and cardboard manufacturing plant (CCMP) located in one of the cities of the Khabarovsk region and in fish (n=27) living in the Amur river downstream was performed using inductively coupled plasma mass spectrometry. The relationship between the level of mercury and cognitive abilities of adolescents was studied.Study Results. An average content of mercury in the upper layer of the soil was 0.85 mg/kg; with the maximum value of the mass fraction of mercury 1.25 mg/kg, the mercury concentration was 8.5-12.5 times higher than the Russian background value. When determining the concentration of mercury in the fish muscle tissue – the main source of organic mercury for children, it was revealed that the content of mercury in the tissues of predatory fish ranged from 0.47-0.52 mg/kg, while the mercury level in non-predatory fish was 0.24 mg/kg. The average mercury content in hair of adolescence was 0.47±0.05 mg/kg and 0.19±0.02 mg/kg in 6-7-year-old children, and it did not exceed the critical level.Conclusion. It was found out that the content of mercury in the soil had significantly decreased compared to 2009, but the level remains above the Russian background value. Mercury content in part of the fish muscle living in the Amur River downstream was higher in predatory species. The concentration of mercury in the children organism permanently living on the territory of anthropogenic pollution did not exceed the threshold level, but the detected background values may have contributed to concentration decrease.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>антропогенное загрязнение</kwd><kwd>экосистема</kwd><kwd>тяжелые металлы</kwd><kwd>Hg</kwd><kwd>ртуть</kwd><kwd>почва</kwd><kwd>рыба</kwd><kwd>дети</kwd><kwd>волосы</kwd><kwd>нейротоксичность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>anthropogenic pollution</kwd><kwd>ecosystem</kwd><kwd>heavy metals</kwd><kwd>Hg</kwd><kwd>mercury</kwd><kwd>soil</kwd><kwd>fish</kwd><kwd>children</kwd><kwd>hair</kwd><kwd>neurotoxicity</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">UNEP Geneva.
