Изложены данные о гидрологии жидкого и твердого стока р. Урал. Гидрохимический мониторинг водоемов бассейна р. Урал проводился в период половодья, в летнюю межень и в осеннюю межень 2017 – 2018 гг. Проведенный гидрохимический мониторинг качества воды природных водоемов Уральского водосборного бассейна позволил выявить превышения ПДКхоз.пит и ПДКрыб.хоз ионов тяжелых металлов в воде обследованных водоемов. Превышение ионов кадмия (1.2 – 1.4) ПДКхоз.пит обнаружено в р. Илек во время межени, а также в р. Урал вблизи границы с РФ в период паводка в количестве (3.1 – 3.4) ПДКхоз.пит и рядом с пос. Жарсуат в период летней и осенней межени найдено в количестве (1.5 – 2.6) ПДКхоз.пит. Установлено превышение концентрации ионов свинца (1.2 – 1.4) ПДКхоз.пит в среднем и нижнем течении р. Урал в разное время года. Превышения концентрации ионов разных тяжелых металлов по сравнению с ПДКрыб.хоз присутствуют во всех водоемах в разные периоды года. Наибольшие превышения ионов цинка по сравнению с ПДКрыб.хоз наблюдались во время межени. </p></abstract><trans-abstract xml:lang="en"><p>A general characteristic of the river basin of the interstate Ural river and information on the economic use of the Ural river in its upper, middle and lower reaches are given. Information on the hydrology of the liquid and solid flow of the Ural river is presented. Hydrochemical monitoring of water bodies of the Ural river basin was conducted during the flood period, during the summer low water period and during the autumn low water period of 2017–2018. The hydrochemical monitoring of the water quality in natural reservoirs of the Ural drainage basin made it possible to identify an excess of the MPCs for residential use and for fishery of heavy metal ions in the water of the examined reservoirs. An excess of cadmium ions by (1.2–1.4) MPC for residential use was found in the Ilek river during its low water as well as in the Ural river near the border with the Russian Federation during the flood period in the amount of (3.1–3.4) MPC for residential use and near the village Zharsuat in the period of summer and autumn low water in the amount of (1.5–2.6) MAC for residential use. An excessive concentration of lead ions by (1.2–1.4) of MPC for fresh water fisheries in the middle and lower reaches of the Ural river at different times of the year was found. Excessive concentrations of ions of different heavy metals in comparison with their MPC for fresh water fisheries were found in all water bodies in different periods of the year. The greatest excess of zinc ions in comparison with its MPC for fresh water fisheries was observed during low water.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>водные объекты</kwd><kwd>трансграничная река</kwd><kwd>речной бассейн</kwd><kwd>мониторинг</kwd><kwd>загрязнения</kwd><kwd>тяжелые металлы</kwd><kwd>гидрохимические показатели</kwd></kwd-group><kwd-group xml:lang="en"><kwd>water bodies</kwd><kwd>transboundary river</kwd><kwd>river basin</kwd><kwd>monitoring</kwd><kwd>pollution</kwd><kwd>heavy metals</kwd><kwd>hydrochemical indicators</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках научно-исследовательской работы по Госзаданию Министерства образования и науки РФ (заявка № 5.3922.2017/64).</funding-statement><funding-statement xml:lang="en">The work was done in the framework of Federal grant No. 5.3922.2017/64 of the Russian Ministry of Education and Science.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Демесинова Г.
