| Title : | CONTENT OF RISK ELEMENTS IN TECHNOSOLS AND THEIR INFLUENCE ON SELECTED SOIL PARAMETERS |
| Abstract : | Mining bodies as remains of mining activities are a source of risk elements that contaminate individual components of the environment and may seriously danger human health. The mining area of Dubnik opal mines (Eastern Slovakia) is known for mining gold, silver, and antimony, but above all, it is a world-famous opal deposit. The study aims to determine the content of risk elements (As, Cd, Cu, Fe, Hg) in soils taken from mining bodies (6 heaps of mining material, 6 open mining pits) and to evaluate their impact on the activity of soil enzymes (urease, acid, and alkaline phosphatase, fluorescein diacetate, and β-glucosidase), nutrient content (Na, K, Mg, Ca) and soil reaction (pH). The aim of the research was also to compare the state of pollution between two types of mining bodies and the influence of pollution on selected soil characteristics. The content of hazardous substances in the soils reached extremely high and above the limit values, especially on the heaps of mining material. Urease was evaluated as the most sensitive soil enzyme while ß-glucosidase showed the highest resistance to contamination. The content of Na, K, and Mg was significantly higher on the heaps of mining material compared to open mining pits. |
