Abstract : The rich mining history in Slovakia has significantly influenced the extent and nature of the current environmental pollution. Owing to insufficient remediation, numerous mine works remain a threat to human health and the surrounding environment. Technical soil samples from two mining bodies (heaps of waste material and open mining pits) from two mining areas were evaluated for Hg content. Technical soil samples were collected directly from the heap surface and from the inside of the mining pits (entrance, middle, and end). The mercury content was determined using an AMA-254 mercury analyzer. Soil pH was determined for all samples. To evaluate the level of pollution, the contamination factor (Cf) and the index of geoaccumulation (Igeo) were determined. The aim of this study was to evaluate the technical soil mercury content and compare the mercury content between mining bodies. The mercury content in the soil samples exceeded the limit values set for Slovak soils. Heaps of waste materials showed significantly higher mercury pollution than open mining pits. Soil pH was significantly negatively correlated with soil mercury content. The values of the contamination factor and index of geoaccumulation showed serious pollution of the mining bodies.
