Abstract:

Theoretical and experimental investigations have revealed significant spatial variations in the chemical element content of wastewater, primarily due to anthropogenic pressures from mining and industrial complexes. This indicates the diverse nature of pollution sources and the complex impact they exert. The most pronounced exceedances of permissible concentrations were observed for manganese, potassium, magnesium, and calcium, attributed to the leaching of elements from rock dumps and chemical weathering processes. Analysis of the total pollution index (Zc) helped identify areas with high levels of technogenic impact, necessitating urgent environmental protection and reclamation measures. Spatial models illustrating element distribution demonstrate a direct correlation between toxicant concentrations in aquatic environments and the location of technogenic objects, particularly spoil heaps. The findings are crucial for future planning of environmental protection initiatives in mining and industrial regions. They enable the identification of areas with the highest ecotoxicological burden and will be utilized for environmental monitoring of water bodies, forecasting ecological risks, and establishing a database for decision-making regarding reclamation and water resource quality management.
