Chemistry for Sustainable Development 18 (2010) 4959 Elemental Blood and Hair Composition of the Russian North Native Inhabitants with Different Biogeochemical Environment

Abstract Elemental composition has been studied for the blood of Chukchi people living in the continental part of Chukotka, and Eskimo people living at the coast of the Bering Bay, as well as for a group of Novosibirsk townspeople. Elemental composition has been determined for the hair of the Chukchi and Yakut people living in the continent. Using the Synchrotron Radiation X-ray Fluorescence An alysis (SR XFA) technique, a simultaneous determin ation of chemical elements in the blood of the mentioned populations has been performed, as it follows: K, Ca, Fe, Cu, Zn, Ge, Se, Br, Rb, Sr, Zr, Pb. The technique potentialities of determining the concentration of chemical elements in the hair of some groups of Yakut and Chukchi men and women using XPA SR have allowed detecting simultaneously K, Ca, Ti, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, As, Se, Br, Rb, Sr, Y, Zr, Mo, Hg, Pb, Bi. Individual, sexual and region al differences in the concentration of elements in blood and hair of the populations under investigation have been established. The data obtained have allowed us to estimate the level of elemental exchange for some groups of Chukchi, Yakut, Eskimo people, to reveal the features of elemental distribution, as well as to perform a certain biogeochemical characterization of the environment
