The comparison of 245 analyses of sands and sandstones with ~375 analyses of the inferred prototype sources of clastic material showed that the lithogeochemical characteristics of arkose and subarkose sands and sandstones (mainly the HFS element content and ratio) makes it possible in most cases to confidently judge the “geodynamic nature” of source felsic igneous rocks.</p></div></div>","PeriodicalId":12781,"journal":{"name":"Geochemistry International","volume":"61 11","pages":"1177 - 1195"},"PeriodicalIF":0.8,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134796581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the geochemical heterogeneity of the primary (pre-Quaternary) biosphere, this resulted in a self-regulating system of ecological niches, within which all local biocenoses and their animal and plant species were maximally adapted to the parameters of the habitat. However, with the emergence of reason, the situation changed fundamentally. Human beings became the dominant species and began the conscious development of new territories, including geochemically unfavorable ones, which led to the formation of zones of stable endemic diseases. Based on this premise, for all existing species, there should be areas with physiologically optimal habitat conditions, i.e., those under which the species has evolved to its present state. It follows that, by being able to record the geochemical parameters of the undisturbed biosphere, it is possible to obtain characteristics that are ecologically ideal for local animal and plant species. In theoretical terms, this allowed us to put forward the hypothesis that by fixing the difference between observed and ideal geochemical conditions, it is possible to build maps of risk of diseases of geochemical nature, including in areas subjected to anthropogenic pollution. The paper outlines the methodology and gives examples of construction of such maps. The obtained results can have an important practical value in organizing the system of sanitary–epidemiological service, in solving the problems of liquidation of the consequences of anthropogenic pollution, and in carrying out preventive measures to minimize the risk of diseases of geochemical nature.</p>","PeriodicalId":12781,"journal":{"name":"Geochemistry International","volume":"61 10","pages":"1074 - 1086"},"PeriodicalIF":0.8,"publicationDate":"2023-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71910414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A biogeochemical assessment is presented for contents of trace elements (Pb, Cu, Zn, Ni, Cd, Cr, and Se) in the trophic chains under certain agroecological conditions, and geochemical factors affecting the accumulation of trace elements in various types of soils and plants growing on them are analyzed. Normative quantitative characteristics are determined for the effects of trace elements on the chemical composition of the soil, the productivity and quality of the plants of grain and of the fodder and vegetable crops. Relationships between major and trace elements when they enter plants are demonstrated to depend on the levels and ratios of the concentrations of the chemical elements in the soil and the physiological needs of the plant organism during its different ontogenesis stages. The parameters of the intake of trace elements into the body of animals with plant fodder under the conditions of model experiments are established.

The basic principles and tasks of multilevel medico-ecological monitoring are described, which make it possible to systematically proceed from the qualitative assessment of the state of the human population health and ecological situation to the quantitative assessment of the ecological health risks and regional standards for permissible levels of technogenic factors, with regard to the probable changes in their effects due to the biogeochemical conditions of the environment. The paper provides verification results of the monitoring methods applied at a regional (Republic of Crimea), subregional (in the cities of Sevastopol and Simferopol), and local (individual cohorts of the urban population) levels. Although the official statistics received from various state departments is less informative for the regional research, it nevertheless allowed us to outline (at a reasonable probability level) territories with contrastingly different parameters of environmental health risk. Subregional (within settlements) biomonitoring in Sevastopol and Simferopol has revealed a spatial heterogeneity and loci with higher contents of some heavy metals and other chemical elements in the environment and biosubstrates (soil and plants). Cohort studies of residents of these cities and assessment of 29 chemical elements in the human organism were followed by the examination of the functional state of target systems in humans belonging to risk groups.
