Abstract

The relevance of the current paper is caused by the need to obtain knowledge about the influence of natural and man-made factors on the human organism (elemental and mineral composition) in the process of urbanization. The main aim of the study is to reveal regional geochemical and mineralogical features of human body ash residue of Norilsk residents in comparison with cities which have been studied earlier, as well as to establish relations between the composition of the habitat and the human organism. The methods used in the study. Unclaimed material was sampling in the Norilsk crematorium with the official permission of admini-stration; elemental composition was detected by instrumental neutron activation analysis and mass-spectrometry with inductively cou-pled plasma; mineral composition was studied by x-ray analysis and scanning electron microscopy; statistical data processing was imple-mented by methods of correlation and cluster analysis; diagramming and comparative analysis were realized via programs such as Stati-stica and Excel. The results. Geochemical and mineralogical features of the studied material were revealed. It was found, that human body ash residue of Norilsk residents concentrates such elements as Mg, Al, P, Ca, Sc, Ni, Rb, Sr, Y, Zr, Cd, Cs, Ce, U and rare earth elements in greater quantities in comparison with previously studied cities. Specific mineral phases of Cu, Pt, Ni, Zn, Au, Zr, rare-earth and radioactive ele-ments were discovered and it shows the copper-nickel specific of Norilsk in the mineral composition of human organism. Based on the results of the elemental and mineral composition, cluster and correlation analysis, the hypothesis about possible source of radioactive, rare-earth elements, Hf and Zr in the human body ash residue of Norilsk residents was offer.
