Until now, there have been laborious researches regarding the presence of heavy metals in environmental factors but their effects have been studied less in the bio-geo-chemical circuits, respectively within the local trophic chains and the regional trophic networks. Naturally, the metals existing in the earth's crust enter the bio-geo-chemical cycles. In the cells of higher organisms, as we know, there is a fragile balance between the amounts of metals needed for catalytic processes and toxic doses to organisms. However, this balance is dependent not only on the concentration and variety of metals in the Earth's crust but also on the microbiological activity of environmental factors, responsible for the transformation of these metals into complex chemical substances that affect more or less the organisms, respectively their enzymatic activity. The vital-necessary, but also the non-vital mineral substances in their mobile forms, which may at one time be toxic to organisms, are significantly pushed out by anthropic activities into trophic chains. They are present in environmental factors such as soil, air, water, reach the body of plants and the body of animals. Plants and animals can bioaccumulate and concentrate in their bodies several chemical elements in the environment, regardless of their origin, which is then easily transferred through food circuits into the human body. Thus, through local trophic chains, respectively through regional trophic networks, contamination of the human body takes place. This requires the need for a measure of most likely high complexity to mitigate the effects with a strong impact on the health status, including that of the human psychic. In severe cases of contamination, behavioral manifestations, especially among the vulnerable population, are proven.

The problem of adaptive, prepathological and pathological reactions of the body to the action of exogenous chemicals is closely intersected with the assessment of the norm and its fluctuations. The imbalance of chemical elements in the human body directly affects the functioning of almost all organs and systems, causing significant stress of adaptation mechanisms. In this article we study the elemental state of the human body depending on the physiological state (endocrine pathology and professional contact with heavy metals), analyze the correlation between macro- and microelements and assess the degree of adaptability of the body. In the work the elemental state of the human body, taking into account not only the absolute values of the concentrations of elements in the hair and whole blood was studied, the adaptability of the body according to the indicators of elemental imbalance in the blood and hair of volunteers, individuals with endocrine pathology (autoimmune thyroiditis and type II diabetes mellitus) and for those working in conditions of contact with heavy metals (for jewelers, welders and batterymen) is analyzed. The results of the study indicate that various non-specific adaptation reactions are accompanied by changes in the elemental state of a person. Under the prevailing pathology of the endocrine system (diabetes mellitus or autoimmune thyroiditis), the adaptation of the body was determined as a stage of tension and is associated with the duration of the disease. In persons exposed to professional contact with heavy metals (Mn, Cr, Pb, Ag), adaptation depended on the nature and duration of professional contact with them: the highest tension of adaptation processes was found in jewelers, and the least in welders and batterymen, which is associated with the duration of professional contact with these metals. The high number of connections between the elements indicates the tension of adaptive reactions in people with endocrine pathology and especially in jewelry workers. Adaptation to the high content of metals in the air of welders and batteries due to the longer experience of these workers and adaptation to production conditions with a decrease in the number of correlations between the elements, as a means of reliable operation.

Introduction. Changes in the body of children and adolescents aimed at adapting to environmental factors are determined by genetic polymorphism in xenobiotic biotransformation genes, determining the degree of susceptibility of the child’s body to pollutants, which is the basis of modern personalized preventive medicine when managing risks to the health of the child population under the influence of environmental factors. Material and methods. Trace elements, including heavy metals, lead and cadmium, were determined in the hair of 256 practically healthy teenagers by atomic absorption spectrophotometry. Depending on the level of content of the latter, two groups of adolescents were formed to determine six genes of the cytochrome P-450 family. Group 1 consisted of adolescents whose cadmium lead content exceeded the average Russian indices. The second group included adolescents whose heavy metals were above the level of average Russian standards. Results. Studies have shown that in adolescents of the 1st group, compared with the data of adolescents of the 2nd group, an increase in the number of carriers of two mutant alleles at the locus rs 1048943 (gene CYP1A1) is 3.08 times, rs 464621 (gene CYP1A1) is 1. 8 times; locus rs 2069522 (CYP1A2 gene) 3.63 times; locus rs 1799853 (CYP2C9 * 2 gene) 4.5 times; locus rs 1057910 (gene CYP2C9 * 3) 3.8 times and locus rs 2279343 (gene CYP2B6) 4.25 times. Moreover, carriers of two normal alleles in adolescents of the first group at the locus rs 1048943 (gene CYP1A1) were 5.14 times; locus rs 2279343 (CYP2B6 gene) was 6.5 fold less than among adolescents of the 2nd group; and at the locus rs 464621 (gene CYP1A1), rs 2069522 (gene CYP1A2), rs 1799853 (gene CYP2C9 * 2), rs 1057910 (gene CYP2C9 * 3) there were no carriers of normal homozygotes. Conclusion. Group 1 adolescents with heavy metal contamination of the body are carriers significantly in a greater number of pathological mutations in the genes of the cytochrome P-450 detoxification system in comparison with data from group 2 adolescents.

Adaptive potential is an indicator of the level of adaptability of the human body to various and changing environmental factors. The adaptive capabilities of the body are influenced not only by external factors, but also by internal - the state of the body as a whole, by the presence or absence of chronic diseases. Therefore, the adaptive potential was used as an integral indicator of a person's adaptability to production factors. The aim of the study was to assess the adaptive capabilities of the organism of workers in greenhouse farms in the Voronezh region. The study was carried out at the enterprises of the closed ground of the region by the method of questioning, the objects of the study were 125 women aged 27-45 years. In most cases, there are violations of the adaptive capabilities of the organism among the studied workers of greenhouse farms, and even a breakdown in adaptation was revealed in 0.8%. In less than half of the cases, the adaptive potential of the greenhouses was within the normal. The adaptive reserves of the greenhouses workers decrease with age.

The aim of the study was to study the content of some heavy metals and arsenic in members of the Cricetidae family of hamsters and to develop centile scales for assessing the level of accumulation of these elements for the Central Federal District. In 2018–2020, hamster`s wool was studied for the accumulation of zinc, copper, iron, lead, cadmium and arsenic by the atomic absorption method. The data on the characteristics of the content of chemical elements in different sexes of animals are given. In the course of the study, it was found that, according to the value of the average content in the wool of animals of the family, the studied elements form the following decreasing series: Fe> Zn> Pb> Cu> Cd> As. When studying the features of the accumulation of chemical elements by different sexes, a significant increase in the concentration of zinc, iron, cadmium and arsenic in the wool of males was established, compared with females, depending on the species, from 1,38 to 3,98; from 1,28 to 1,52; from 2,00 to 304,00 times, respectively. With regard to the accumulation of copper in the body, the opposite trend is observed. In females, its concentration is 1,5–3,19 times higher. In the studied sample of animals, an increase in copper content was revealed in 44,83% of individuals and a decrease in cadmium in 44,82%.

Abstract The rocks of the earth's crust and upper mantle belong to three categories. The first includes those rocks that have achieved complete equilibrium. Rocks of the second category represent transitory equilibrium, their formation varying relative to the chemical elements available and the physical and dynamic conditions. Rocks of the third category consist of limestones, shales, and other detrital sediments. Their composition is completely controlled by that of the source rock. The global discontinuities including that at the surface, and the Mohorovicic and Lehmann-Gutenberg discontinuities are briefly discussed in terms of differences in densities of rocks of the various categories.

Gold mining activities can increase people's income and be detrimental if the correct processing process does not follow the implementation. This illegal gold mining and processing of gold ore use mercury. In the gold laundering process, who should carry out mercury with the correct procedures and knowledge. Still, in this illegal gold mining, the miners wash gold using mercury without using personal protective equipment so that the miners are in direct contact with the mercury used. Continuous, direct contact with heavy metals can cause an increase in chemical elements in the body caused by the bioaccumulation system. The purpose of this literature review is to determine the health problems caused by heavy metals in illegal gold mining. The database searches used are Garuda Portal and Google Scholar. There were 24 articles, and only ten were used, which were suitable through analysis of objectives, suitability of topics, analysis of results, and research locations. Based on the results of studies conducted, miners suffer from chronic and acute diseases. Chronic diseases suffered are liver dysfunction, decreased leukocytes, paralysis of limbs, numbness, and tremors. Symptoms felt by Parkinson's disease are constantly shaking hands and feet, facial muscles always moving involuntarily. Lips move unconsciously, lack passion for activities, difficulty sleeping, sometimes peaking emotions, poor memory, cramps during cold weather conditions, and often feel anxious. In contrast, the acute diseases that arise are acute poisoning, diarrhea, ARI, eye disease, vertigo, miscarriage, skin disease.
