To evaluate elemental system of residents of Magadan town, children, aged 1-3, were surveyed. Content of 25 chemical elements was measured by atom-emission spectrometry with inductively bonded argon plasma. As it is turned out from results, deficiency of Co is discovered in 88% of children, Mg - in 73 %, Cu - 57 %, Ca - 51 %, Mn - 49 %, Fe - 41 %, P - 33 %, Se - 31 %, Zn - 29 %, K and Na - 25 %. Excess content of Cr and Na (43 %), Si (29 %), Fe and K (25 %) in hair samples was rarely noted. Content of heavy metals is in the range of ordinary values, only in isolated cases excess of Li, Pb and B was discovered. On the basis of power and number of correlations, index of adaptation level of elemental system was measured. Its value is 9,14 rel.un and it can be a consequence of physiological immaturity of functional systems of infantine organism. Surely it is necessary to correct existing misbalance of macro- and trace elements by enrichment of food ration necessary nutrients in order to prevent its deficiency.
