Использование населением отработанных техногенных водоёмов для целей рекреации и обеспечения хозяйственно-бытовых потребностей может представлять потенциальную опасность для здоровья. Такие загрязнения, как тяжёлые металлы, не подвергаются процессам разложения, а аккумулируются в биотических и абиотических компонентах водоёма. Впоследствии опасные токсиканты по пищевым цепям могут попадать в организм человека. Проведена эколого-гигиеническая оценка состояния оборотного водохранилища Семёновской золотоизвлекательной фабрики.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Объект исследования находится в Зауралье Республики Башкортостан по географическим координатам 52°30′20″N, 58°19′48″E. Изучено содержание тяжёлых металлов (Zn, Cu, Pb и Cd ) в воде, донных отложениях и биомассе водного макрофита (Potamogeton perfoliatus L.). Измерения массовых концентраций металлов выполнены методом инверсионной вольтамперометрии. В донных отложениях определены подвижные формы металлов, извлекаемые ацетатно-аммонийным буфером с рН = 4,8.</p></sec><sec><title>Результаты</title><p>Результаты. Выявлено, что в воде уровень тяжёлых металлов выше предельно допустимых концентраций для водоёмов рыбохозяйственного значения: по меди в 19–27 раз, по цинку – в 10–24 раза, по свинцу – в 2,7–5,8 раза, по кадмию – в 1–1,4 раза. Превышение нормативов для водных объектов хозяйственно-питьевого и культурно-бытового водопользования регистрируется по кадмию (в 6 раз) и свинцу (в 2,5 раза). В донных отложениях содержание подвижных форм цинка составляет 372,00 ± 28,51 мг/кг, меди – 144,37 ± 4,08 мг/кг, свинца – 14,09 ± 1,48 мг/кг, кадмия – 0,036 ± 0,002 мг/кг. Суммарный показатель (ZC ), отражающий аддитивное превышение фона, равен 1686, что соответствует чрезвычайно высокому уровню техногенного загрязнения донных отложений. Концентрации тяжёлых металлов в надземных и подземных органах рдеста многократно превышают фоновые уровни.</p></sec><sec><title>Заключение</title><p>Заключение. Отработанное оборотное водохранилище Семёновской золотоизвлекательной фабрики представляет потенциальную опасность для здоровья местного населения при его использовании для разведения домашней птицы, водопоя скота, рыбной ловли. Необходимо проведение мероприятий, направленных на улучшение эколого-гигиенической ситуации на территории населённого пункта.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. The population using waste man-made water reservoirs for recreation and providing household needs can be at potential health risk. Such pollutants as heavy metals do not undergo decomposition processes. They accumulate in the biotic and abiotic components of the reservoir. Subsequently, hazardous toxicants can enter the human body through food chains. An ecological and hygienic assessment of the state of the waste reverse reservoir of the Semyonov gold recovery plant has been carried out.</p></sec><sec><title>Material and methods</title><p>Material and methods. The object of the study is located in the Zauralye of the Republic of Bashkortostan at the geographical coordinates 52° 30’20″ N, 58° 19′48″ E. The content of heavy metals (Zn, Cu, Pb, and Cd) in water, bottom sediments and biomass of aquatic macrophyte (Potamogeton perfoliatus L.) was studied. In the bottom sediments, mobile forms of metals have been detected. They are extracted by an acetate-ammonium buffer with pH = 4.8</p></sec><sec><title>Results</title><p>Results. It has been revealed that in water the concentration of heavy metals is higher than the maximum permissible concentrations for fishery reservoirs: 19–27 times for copper, 10–24 times for zinc, 2.7–5.8 times for lead, 1–1.4 times for cadmium. Exceeding the standards for water bodies for drinking, domestic and cultural water use is recorded for cadmium (6 times) and lead (2.5 times). In bottom sediments, the zinc content of mobile forms is 372.00 ± 28.51 mg/kg, copper - 144.37 ± 4.08 mg/kg, lead - 14.09 ± 1.48 mg/kg, cadmium - 0.036 ± 0.002 mg/kg. The total index (ZC ), reflecting the additive excess of the background, is 1686, which corresponds to an extremely high level of man-made pollution of bottom sediments. The concentrations of heavy metals in the aboveground and underground organs of Potamogeton perfoliatus L. are much higher than the background levels. </p></sec><sec><title>Conclusion</title><p>Conclusion. The waste reverse reservoir of the Semenov gold extraction factory is potentially dangerous to the local population health when it is used for breeding poultry, watering cattle, and fishing. The activities aimed at improving the environmental and hygiene situation in the territory of the locality are imperative.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>тяжёлые металлы</kwd><kwd>техногенное загрязнение</kwd><kwd>оборотное водохранилище</kwd><kwd>донные отложения</kwd><kwd>водные макрофиты</kwd><kwd>биоаккумуляция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>heavy metals</kwd><kwd>man-made pollution</kwd><kwd>reverse water reservoir</kwd><kwd>bottom sediments</kwd><kwd>water macrophytes</kwd><kwd>bioaccumulation</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">Kivinen S., Vartiainen K., Kumpula T.
