THE CONTENT OF MICROELEMENTS RESIDENTS VARIOUS ETHNIC GROUPS OF THE MAGADAN REGION

The article presents the results of a study of the element status of residents of different ethnic groups (Koryak, even, mestizo) Magadan region. By atomic emission and mass spectral analizovs inductively coupled plasma quantity content of co, cu, Fe, Zn, si, al, cd, Pb, sn, Hg hair. there was a slight deviation of the content of some essential elements (copper, iron, zinc) in aboriginal and Métis on average. it is suggested that this phenomenon is caused by adaptation to the conditions of the indigenous population of the north. these low levels of heavy metals - aluminum, cadmium, lead, tin, cobalt, mercury, indicates the relative well-being of the environment in terms of pollution with toxic elements. the higher silicon content in the hair of aboriginal and Métis is consistent with the data that the Magadan region is silicic province. Variability of the most studied trace elements higher in the Métis compared with the natives. High individual variability of chemical elements can be the result of an imbalance element in disadaptative organism to the environment, or a manifestation of the individual characteristics of the organism. the possible consequences of deficiency and excess of trace elements in the indigenous population of the north.
