The influence of anthropogenous and geochemical environmental factors on the elementary status of children of Chelyabinsk Region

The purpose of the work is to study the peculiarities of the elementary status of the children of Chelyabinsk region, living in the settlements similar in geochemical features, but various in the level of anthropogenic load and determine a major factor of mineral metabolism provision. The results of the study of hair trace elements content in 235 pupils of secondary school aged from 7 till 18 years are presented. All of them lived in the towns: Varna, Karabash and Tomino (Chelyabinsk region), located near the copper-porphyry ores, where commercial development of minerals was carrying out for a long time. The elementary status (40 chemical elements) was estimated by methods ICP-AS and ICP-MS in the Center of Biotic medicine (Moscow). Statistical processing of the results was carried using a program STATISTICA 8.0. It was established that irrespective of the place of residence for the examined children the deficiency of Se, Co, Cr was revealed, that was probably bounded to geochemical features of the territory of accommodation. The greatest impact on the elementary status was exerted by the level of anthropogenic loading. Children from Karabash had considerable excess of the recommended As and Pb values content in the hair; also they had the maximal, in comparison with other settlements, hair Cd, Be, Tl, Ba, Ag, Ni, Sn and Sb content. Children from this settlement had low Ca, Mg, P, B, Sr (the main osteotropic chemical elements) content in hair. Larger accumulation of Cu and Ni in hair of children from Karabash was connected with the ecological situation in the settlement and caused by emissions of Karabash copper-smelting plant.
