Материалы и методы: в ходе данного исследования проанализированы 915 историй болезней пациентов Республиканского кожно-венерологического диспансера, проживающих более 5 лет на территории гидрогеохимической аномалии. Изучение этнической предрасположенности к развитию кожных патологий проводилось на основе анализа имеющихся литературных данных. Результаты: 40,6 % населения исследованных территорий используют для питья артезианскую воду с содержанием мышьяка в 20-50 раз выше гигиенического норматива. Преобладающей локализацией в анализе общей структуры кожных заболеваний неинфекционной природы по районам исследований являются различные формы псориатического процесса, которые были выявлены у половины пациентов (51,6 %). Распространение кожных патологий среди разных этнических групп населения Северного Дагестана не выявило различий. Выводы: выявленные среди населения клинические случаи дерматитов у пациентов Республиканского кожно-венерологического диспансера характеризуются симптомами, характерными для описанных в литературе арсенодерматитов. Для верификации данных необходимо проведение детальных исследований с использованием биомаркеров (волосы, моча) у экспонированных групп населения с выявленными кожными патологиями, потребляющих для питья воду с разным уровнем содержания мышьяка.</p></abstract><trans-abstract xml:lang="en"><p>Objective: to study the epidemiological features of the spread of arsenodermatitis among the population of Northern Dagestan with the identification of populations most exposed to arsenic. Materials and methods: in the course of this study, 915 case histories of patients of the Republic Dermatovenerologic Dispensary, who have lived for more than 5 years in the territory of the hydrogeochemical anomaly, were analyzed. The study of ethnic predisposition to the development of skin pathologies was carried out on the basis of an analysis of available literature data. Results: 40.6 % of the population use artesian water with arsenic contamination 20-50 times higher than the permissible level for drinking. The prevailing localization in the analysis of the general structure of skin diseases of a noninfectious nature by study areas is the various forms of the psoriases, which were detected in half of the patients (51.6%). The spread of skin pathologies among different ethnic groups in North Dagestan did not reveal any differences. Conclusions: the clinical cases of dermatitis among the patients of the Republic Dermatovenerologic Dispensary revealed in the population are characterized by symptoms similar to those described in the literature of arsenodermatitis. To verify the data, it is necessary to conduct detailed studies using biomarkers (hair, urine) in exposed groups of the populationwith identified skin pathologies consuming water with different levels of arsenic for drinking.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>артезианские воды</kwd><kwd>питьевое водоснабжение</kwd><kwd>мышьяк</kwd><kwd>арсенозы</kwd><kwd>кожные патологии</kwd><kwd>арсенодерматиты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>artesian water</kwd><kwd>drinking water</kwd><kwd>arsenic</kwd><kwd>arsenoses</kwd><kwd>dermatitis</kwd><kwd>arsenodermatitis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">РФФИ, в рамках научного проекта № 18-35-00501 мол_а «Оценка влияния природных гидрогеохимических особенностей на качество питьевых вод и  формирование канцерогенных рисков здоровью населения  (на примере Республики Дагестан)».</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">Абдулмуталимова Т.О., Ревич Б.А.
