Abstract

The relevance of the research is defined by the need of accounting the fullest information on chemical composition of underground waters by their preparation for economic and drinking use. Earlier there were the data for the basin of Upper Ob mainly on macrocomponent structure, permanganate oxidizability, biogenic elements and content of limited quantity of minerals. This did not allow estimating the objective potential impact of regional factors with the toxicological and sanitary and toxicological limiting signs of influence. The main aim of the research consists in assessment of microelement composition of underground waters of the operated horizons of the top hydrogeodynamic zone in the basin of Upper Ob (in the territory of the Altai-Sayansk hydrogeological folded region and areas of the West Siberian artesian basin adjoining it). Objects: the underground waters used for drinking water supply in the basin of Upper Ob (the territory of Altai Republic, Altai Krai, the Novosibirsk, Kemerovo and Tomsk regions). Methods: the modern methods of definition of chemical composition of underground waters, including: in 2019 - mass and spectrometer method with inductively bound plasma (ICP MS); in 1998 - neutron activation analysis; statistical methods. Results. The authors have carried out the analysis of chemical composition of the underground waters used for economic and drinking water supply in the basin of Upper Ob. The received results allow expanding significantly the idea of microelement composition of underground waters of the considered territory. It is shown that the level of content of the majority of the studied minerals is less than standards of quality established in the Russian Federation. However the index of the additive influence (the sum of the relations of the actual and maximum-permissible concentration of substances of 1-2 hazard classes of ∑C1-2/MPC) is frequently more than a unit that indicates potential toxic impact on health when using underground waters without the corresponding water treatment. The highest ∑C1-2/MPC values (more than 5) are noted for underground waters in Altai Krai and Altai Republic, in the villages of Habazino, Onguday and Talmenka (reservoirs of inflows of Ob - the rivers Aley, Katun and Chumysh, respectively). Taking into account the established ore occurrences and the nature of concentrating of paragenetic associations of chemical elements in underground waters of the region, the authors made the assumption of substantial contribution of natural factors in formation of observed level of maintenance of many minerals.
