ABSTRACT. The purpose of this study was to identify the features of the elemental status of first-year students from various climatic and geographical regions of the world who arrived to study in the Russian Federation.

Materials and methods. The analysis of the studied biological samples (hair and urine) of students from the Peoples' Friendship University of Russia (PFUR) was performed by inductively coupled plasma mass spectrometry (ICP-MS) with the determination of the content of 12 elements, including Co, Cu, Fe, I, Mg, Mn, Se, Zn, As, Cd, Hg, Pb.

Results. According to the results of the study, significant features of the exchange of both essential and toxic elements in foreign students were revealed. In particular, the analysis of the accumulation of toxic elements in the body of RUDN first-year students indicates a significant increase in the level of toxic elements in foreign students. Thus, for students from Latin America and Africa, signs of an excess of Hg and Pb, respectively, are more characteristic. With regard to essential elements, the most pronounced deficiencies were noted in the case of Fe, I, Mg, among students from Southeast Asia.

Conclusion. The results of the study creates the prerequisites for taking measures to correct the provision of the body of students with these elements.
