Human health is largely related to the influence of various environmental factors operating in the area of residence, one of which may be the entry of high or low concentrations of chemicals into the human body. Aim of the study: analysis of the chemical composition of environmental components (water, food) and their influence on the microelements` balance in the hair of teenagers of different ethnic groups in the Okhotsky district. Object of study: teenagers of Russian and Even nationality. The content of Fe, Cu, Zn, Se in hair and water was determined by atomic emission spectroscopy. Results: analysis of drinking water showed an excess of Fe and Cu, low levels of Zn and Se. The content of essential microelements in the average daily diet is deficient in all groups. Deficiency of Cu and Zn in the hair of teenagers is due to low content in the average daily diet. Correlations were established for low Se content in water and hair in the Evens, and Zn in the Russians. Correlations in the Even group are stronger compared to Russians. Thus, the deficiency of essential microelements in the environment affects content in the human body.
