Вода является ключевым источником жизни на Земле, который участвует в переносе питательных веществ, макро- и микроэлементов между почвой, растениями, животными и человеком, а также в концентрировании и диспергировании химических элементов и образовании минералов. Элементный статус населения во многом определяется химическим составом природных вод территории проживания.</p></sec><sec><title>Цель исследования</title><p>Цель исследования: сравнительный анализ концентрации железа, марганца, кальция и магния в природных водах Ханты-Мансийского и Ямало-Ненецкого автономных округов.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Изучена концентрация Fe, Mn, Ca и Mg в 100 пробах природных вод (реки, озера, заводи, протоки и пр.) Ханты-Мансийского (ХМАО) и Ямало-Ненецкого (ЯНАО) автономных округов: по 50 проб из каждого методами спектрофотометрии, капиллярного электрофореза и атомно-абсорбционной спектрометрии. Полученные результаты сравнивали с референтными значениями СанПиН 1.2.3685–21.</p></sec><sec><title>Результаты</title><p>Результаты. Установлено превышение ПДК по Fe в большинстве проб обоих округов и по Mn – в ХМАО на фоне крайне низких концентраций Са и Mg в подавляющем числе анализов поверхностных вод ХМАО и ЯНАО. При этом отмечено достоверно меньшее содержание Са (р = 0,012) и Mg (р = 0,021) в пробах природной воды ЯНАО сравнительно с ХМАО.</p></sec><sec><title>Заключение</title><p>Заключение. У населения тюменского Севера постоянное употребление с питьевой целью подобной воды может привести к раннему развитию и быстрому прогрессированию сердечно-сосудистых и костно-суставных заболеваний, сахарного диабета 2-го типа, новообразований и пр., при этом существует потенциальная опасность генерализации иммунодепрессивных состояний, заболеваний ЦНС, ЖКТ, нарушений окислительного метаболизма и пр.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background: Water is a key source of life on Earth; it is involved in the transfer of nutrients, macro- and microelements between soil, plants, animals and humans, as well as in the concentration and dispersion of chemical elements and the formation of minerals. The elemental status of the population is largely determined by the chemical composition of the natural waters on the territory of residence.</p></sec><sec><title>Objective</title><p>Objective: To perform a comparative analysis of the concentrations of iron, manganese, calcium and magnesium in natural waters of the Khanty-Mansiysk and Yamalo-Nenets Autonomous Districts (Okrugs).</p></sec><sec><title>Materials and methods</title><p>Materials and methods: We established concentrations of iron, manganese, calcium and magnesium in 100 samples of natural waters taken from rivers, lakes, backwaters, channels, etc. of the Khanty-Mansiysk and Yamalo-Nenets Autonomous Districts, 50 samples each, using spectrophotometry, capillary electrophoresis and atomic absorption spectrometry. The results obtained were compared with the reference values provided in Russian sanitary rules and regulations SanPiN 1.2.3685–21.</p></sec><sec><title>Results</title><p>Results: We established elevated levels of iron in most surface water samples from both districts and of manganese in the Khanty-Mansi Autonomous Okrug accompanied by extremely low concentrations of Ca and Mg in the vast majority of all samples. At the same time, we registered significantly lower concentrations of Ca (p = 0.012) and Mg (p = 0.021) in the water samples from the Yamalo-Nenets Autonomous Okrug compared to those from the other district.</p></sec><sec><title>Conclusion</title><p>Conclusion: In the population of the Tyumen North, the constant use of such water for drinking purposes can lead to the early development and rapid progression of cardiovascular and osteoarticular diseases, type 2 diabetes, neoplasms, etc.; at the same time, people are at risk of generalization of immunosuppressive conditions, diseases of the central nervous system, gastrointestinal tract, oxidative metabolism disorders, etc.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Север</kwd><kwd>природные воды</kwd><kwd>железо</kwd><kwd>марганец</kwd><kwd>кальций</kwd><kwd>магний.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>North</kwd><kwd>natural waters</kwd><kwd>iron</kwd><kwd>manganese</kwd><kwd>calcium</kwd><kwd>magnesium</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">Горбачёв А.Л.
