The elemental status of an organism depends on the concentration of impurities of chemical elements in the environment which determines the state of health. Aim of the study: to study the level of influence of the chemical composition of soil and water on the elemental status of adolescents living in the Khabarovsky Kray. We conducted a survey of adolescents living in the Okhotsky (n=72) and Nikolaevsky (n=49) districts of the Khabarovsky Kray. We have determined the content of Fe, Cu, Zn, Se, Th and U in hair, water and soil by atomic emission spectroscopy. Results: Significant correlations were found between the content of Fe, Th in hair and water (r=0.52-0.89), Fe, Cu, Zn, Se in hair and soil (r=0.38-0.71). The value of correlation relationships among adolescents living in the Nikolaevsky region is 1.5 times higher than among teenagers living in the Okhotsky region. Thus, the chemical elements in water and soil influence the formation of the elemental status of adolescents and contribute to the functional state of the body.
