Potencionální environmentální dopady hornických deponií ložisek železných rud na složky životního prostředí (Přičný vrch, Zlatohorský rudní revír).

Abstract

This dissertation deals with the issue of possible contamination of environmental components as a result of long-term mining of polymetallic, copper and gold-bearing ores in the territory of the ore district of Zlaté Hory. During mining, anthropogenic shapes are created in the landscape. These give it an unmistakable appearance, but potentially toxic elements can enter the environment from them. On the other hand these anthropogenic shapes create conditions for the creation of new biotopes. In the theoretical part, the extraction of mineral resources, the risks associated with it and its impact on the environment are described. Then the selected potentially toxic elements and their properties are also described. The practical part is focused on the concentrations of potentially toxic elements (PTE) in individual components of the environment. Soil, sediment, water and biota samples were analyzed. The resulting concentrations were compared with the limit values of the relevant legislation and it was assessed whether the monitored area is contaminated as a result of anthropogenic activity or whether it is the natural geological background of the ore district of Zlaté Hory. Recommendations for further research dealing with this topic could be the expansion of the monitoring network, the more efficient location of individual sampling points, the addition of reference areas and comparison with other areas affected by mining. For example, a study of PTE accumulation in aquatic organisms could be interesting.
