Features of the elemental status of the indigenous population of the south of Central Siberia

Particularly relevant are studies to establish the microelement status of territories in environmentally unfavorable regions with high anthropogenic load, which include the Krasnoyarsk Territory. Natural and geochemical features of territories, as a complex of factors constantly acting on the human body, can cause not only endemic diseases, but also potentiate anthropogenic effects. A large number of studies on geochemistry, biogeochemistry, soil science, and the ecology of microelements in the natural environment have been carried out in different regions of Siberia. At the same time, in the southern part of the Krasnoyarsk Territory, data on a comprehensive assessment of the content of microelements in different parts of the ecosystem have not been sufficiently studied, summarized and systematized. Thus, the purpose of the work was to study the characteristics of the elemental status of the indigenous population of the south of Central Siberia. Laboratory studies to determine the concentration of trace elements in the hair of the examined individuals were carried out using mass spectrometry with inductively coupled argon plasma. When considering the results of the study, certain groups of the population of the city of Krasnoyarsk were recorded in elemental status between the sexes. In men, there was an increase in potassium content by 1.7 times, phosphorus by 1.2 times relative to the 75th centile. The content of cobalt and calcium corresponded to the 25th centile of normal content in bio substrates. For women living in the city of Krasnoyarsk, an increased excretion of calcium and zinc from the body by 1.2 times relative to the 75th centile was noted. In this gender group, normal average and median values for the content of iron and chromium in bio substrates (hair) have been established and are 21 and 0.46 μg/g, respectively. The level of toxic elements such as nickel, mercury, cadmium and lead were normal and the range of maximum values did not exceed the 75th centile interval in both study groups.
