Abstract
Introduction. One of the priorities of the regional policy of the Khabarovsk Territory is the preservation of the health of the indigenous peoples of the North. The full content of essential elements and the minimum presence of toxic and radioactive elements is one of the most important components of the normal functioning of the organism. Aim. To identify the features of the elemental composition of hair and blood serum in the body of adolescents of different ethnic groups of the North of the Khabarovsk region against the background of increased uranium and thorium content. Materials and methods. The survey of adolescents (n=121) was done: Nivkhs, Evenks and Russians. The content of Fe, Cu, Mo, Zn, Co, Se, Th, and U in hair and blood serum was found by atomic emission spectroscopy. Results. An elemental imbalance was found in all groups: an excess of Fe, Cu, Mo, Th, U and a deficiency of Co, Se was detected in the blood serum of Nivkhs and Evens; deficiency of elements was found in the blood serum of Russians; the content of U is excessive in all groups. The concentration of Fe, Th, U was excessive, Cu, Se was deficient in the hair. The dependence between the elemental composition of biosustrates and the nutritional composition of the diet was identified. Significant correlations between the high content of Th and U and imbalance of essential elements was found out. A high concentration of Th and U in biosubstrates is one of the risk factors for the violation of elemental homeostasis in adolescents in Khabarovsk Territory. Conclusion. The determination of features of microelement status allows to identify risk groups for the development of disadaptation states of the Nivkhs and Evens and determine the necessary correction measures.
