Abstract
The results of a study on the content of toxic metals in the hair of first-year students of the Peoples Friendship University of Russia who arrived for training from various climatogeographic regions of the world are presented. The research involved first-year students from Africa, Latin America, the Near and Middle East, and Southeast Asia. A group of first-year students from the Moscow region acted as a control during the research. Studies have shown that there are significant differences in the content of toxic metals (Al, As, Hg, Pb, Cd, Sn) in the hair of foreign first-year students, depending on the region of residence. Students from Africa and Latin America were characterized by the highest content of toxic metals in their hair.
