The study included 103 Evenks living in the rural area of Jilinda in the Oleneksky district of Yakutia. The concentration of 4 major elements was determined in the blood serum by mass-spectrometry: sodium (Na), magnesium (Mg), phosphorus (P), calcium (Ca). The study revealed a reduced level of calcium (72.8 mg/L) and an increased concentration of phosphorus (130.3 mg/L) in the serum of Evenks compared to the literature data, which may affect the development of diseases in this ethnic group.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>основные элементы</kwd><kwd>сыворотка</kwd><kwd>коренные народы Севера</kwd><kwd>эвенки</kwd><kwd>Арктика</kwd><kwd>натрий</kwd><kwd>магний</kwd><kwd>фосфор</kwd><kwd>кальций</kwd></kwd-group><kwd-group xml:lang="en"><kwd>major elements</kwd><kwd>serum</kwd><kwd>indigenous peoples of the North</kwd><kwd>Evenks</kwd><kwd>Arctic</kwd><kwd>sodium</kwd><kwd>magnesium</kwd><kwd>phosphorus</kwd><kwd>calcium</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда № 22-25-20095, https://rscf.ru/ project/22-25-20095/.</funding-statement><funding-statement xml:lang="en">This work was supported by Russian Science Foundation No 22-25-20095, https://rscf.ru/en/project/22-25-20095/.</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">Биоэлементный статус у больных с кальцинированным аортальным стенозом / Н.И.
