Целью исследования явилось проведение сравнительного анализа содержания токсичных металлов в волосах студентов из различных регионов.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Проведено обследование студентов, поступивших на первый курс РУДН, проживающих в России, а также прибывших из Азии, Ближнего Востока, Африки и Латинской Америки. Определение содержания алюминия (Al), мышьяка (As), кадмия (Cd), ртути (Hg), свинца (Pb) и олова (Sn) в волосах осуществляли методом масс-спектрометрии с индуктивно-связанной плазмой.</p></sec><sec><title>Результаты</title><p>Результаты. Установлено, что максимальное содержание алюминия, кадмия и свинца характерно для студентов из Африки и Латинской Америки. Наиболее выраженная кумуляция ртути отмечена в волосах первокурсников, прибывших из Латинской Америки. В то же время уровень мышьяка в волосах обследуемых из всех регионов превышал соответствующие значения у студентов из России более чем в 2 раза. При этом сколько-нибудь значимых групповых различий в содержании олова выявлено не было. В регрессионных моделях предиктором повышенного содержания ртути в волосах явилось проживание в Азии, Африке, а также Латинской Америке. Проживание в Африке также было достоверно связано с более высокими показателями содержания свинца. В случае кадмия прямая взаимосвязь между проживанием в Латинской Америке и уровнем металла в волосах приближалась по значимости к достоверной.</p></sec><sec><title>Заключение</title><p>Заключение. Полученные данные свидетельствуют о повышенной кумуляции токсичных металлов, особенно ртути, свинца, кадмия, в организме первокурсников, прибывших в первую очередь из стран Африки и Латинской Америки, что может оказывать негативное влияние на состояние здоровья и эффективность обучения студентов-иностранцев. В то же время необходимы дальнейшие исследования, направленные на оценку непосредственного вклада избытка токсичных металлов в организме в показатели здоровья студентов РУДН.</p></sec></abstract><trans-abstract xml:lang="en"><p>The aim of the study was to perform a comparative analysis of hair content of toxic metal in foreign students originating from different regions.</p><sec><title>Material and methods</title><p>Material and methods. An examination of first-year students of the RUDN University originating from Russia, Asia, the Middle East, Africa, and Latin America was performed in the study. Assessment of hair aluminum (Al), arsenic (As), cadmium (Cd), mercury (Hg), lead (Pb) and tin (Sn) content was undertaken using inductively-coupled plasma mass spectrometry.</p></sec><sec><title>Results</title><p>Results. The obtained data demonstrate that the highest levels of Al, Cd, and Pb were observed in students originating from Africa and Latin America. The most prominent mercury accumulation was detected in subjects from Latin America. In turn, hair As content in foreign students from all regions exceeded the respective Russian values by a factor of more than two. No significant group difference in hair tin content was observed. In regression models, prior habitation in Asia, Africa, and Latin America is considered as a significant predictor of elevated hair Hg content. African origin was also associated with higher Pb levels in hair. In the case of cadmium, a direct relationship between prior habitation in Latin America tended to be significant.</p></sec><sec><title>Conclusion</title><p>Conclusion. The obtained data revealed increased accumulation of toxic metals, especially, Hg, Pb, and Cd in the hair of foreign first-year students originating from Africa and Latin America, that may have a significant adverse effect on health and educational performance. At the same time, further studies aimed at investigating the particular contribution of toxic metal overload to health effects in RUDN University students are required.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>студенты-иностранцы</kwd><kwd>ртуть</kwd><kwd>кадмий</kwd><kwd>свинец</kwd><kwd>токсичность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>foreign students</kwd><kwd>mercury</kwd><kwd>cadmium</kwd><kwd>lead</kwd><kwd>toxicity</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">Li Y., Zhou Q., Ren B., Luo J., Yuan J., Ding X. et al.
