Soil Material Quality and Environmental Potential of Metallically Contaminated Soils

Abstract:

The paper presents the results of the evaluation of the environmental potential of soils in the area affected by the long-term mining activity. The environmental potential index consists of a numerical expression of the ability to provide water storage, immobilization of risk elements, and immobilization and transformation of organic pollutants. The exceedance of the limit values Hg, Cu, Zn, As, Cd and Pb was found in the soils of the investigated area of central Spiš. The rate of soil immobilization of risk elements is very low to high. The point value expressing the ability of agricultural lands to provide environmental functions is very low to medium in the studied areas, the financial expression of the values of the environmental potentials indexes is in the range of 7 100 to 14 000 € ha^-1, while the average value of 1 ha of agricultural land in Slovakia is about 14 200 €.
