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.
