Peoples' Friendship University of Russia, Miklukho-Maklai Street, 6, Moscow, 117198, Russia
ABSTRACT. The purpose of this study was to study the elemental status of first-year students of the Russian University of Friendship of Peoples who arrived to study from various climatogeographic regions of the world. Studies have shown that first-year students who came to study from different climatogeographic regions of the world are characterized by significant differences in the elemental composition of hair. Students from Latin America are characterized by a relatively high level of toxic metals Al, As, Hg, Sn, and students from Africa stand out by the highest levels of Al, B, Cd, Fe, I, Mn, Ni, Pb, Si, Sn, V. students from Iran and Azerbaijan revealed the minimum value of Co, Cu, Fe, I, Mg, Mn, Sn, V among all the studied groups. It was established that there are significant differences in the content of Ca, K, Mg, Na, P in the hair of male students from different regions of the world. Male students from Africa were characterized by the lowest Ca and P content in their hair, and the highest Mg content. The lowest content of K and Na was found in students from the countries of the Near and Middle East.
