[COMPARATIVE ANALYSIS OF TRACE ELEMENT COMPOSITION OF HAIR IN URBAN RESIDENTS OF WESTERN SIBERIA].

There was performed a study of the element status (hair analysis) of the population of the two cities of Western Siberia: Surgut (n = 350) and Omsk (n = 385). Detection of elements was performed by atomic emission and mass spectrometry methods. The population of Surgut when compared with residents of Omsk bioelements were characterized by a more high content of B, Cu, Co, Fe, Mg, I, Zn (p < 0.001), and a lower content of Cr, Se (p < 0.001). Scarce elements for Omsk residents were 1, Se. In hair of Surgut residents in more higher concentrations there were detected toxic and potentially harmful elements such as Pb, Hg, Be, Cd, Li, Sn (p < 0.001). At the same time there were lower than in Omsk residents values of concentrations of Al, As, V In comparison groups there are established statistically significant differences of coefficients used for the evaluation of the metabolic activity, such as the Na/K, Ca/K, Na/Mg, Fe/Cu. In a sample of the city of Surgut coefficients Ca/K, Fe/Cu and "toxicity index" had the high values. The established differences in the availability of macro- and trace elements for the population of territories are determined by climatogeographic, geochemical features and the specificity of the structure of nutrition.
