The purpose of the study is to research mineral composition of the ash residue of the human body in some cities of Russia (Norilsk, Novokuznetsk, Novosibirsk, Yekaterinburg, Rostov-on-Don, St. Petersburg) and also to determine how much the composition of the environment is reflected in the composition of the human body. The research material is samples of the ash residue of the human body – the material remaining after burning the human body in the crematorium, sampled by official permission of the institution’s administration from unclaimed material. Long-term study of the geochemical features of such an object has generated interest in studying the mineral composition of the material and the reflection of the environment in its features. The study of the mineral composition carried out by X-ray diffraction analysis using a powder diffractometer and scanning electron microscopy. In total, 125 ash residue samples studied during the study. The micromineral phases of 30 chemical elements revealed, reflecting their increased content in the test material, as well as, to some extent, the composition of the habitat. Despite the obvious transformation of minerals during burning of the matter, it was found that the composition of the phases detected reflects the geochemical features of the technogenesis of the studied territories: the extraction and processing of copper and platinum ores in Norilsk, the refining production in Novosibirsk, and the increased arsenic content in the environment of Novokuznetsk, significant dust load attributable to residents of Novokuznetsk and Norilsk, the contribution of road transport in cities with high traffic load, etc. The data on the material composition of the ash residue of the human body emphasizes the need for a detailed study of minerals both directly in living organisms and in the products of their transformation |
