Mapping of old impacts caused by mercury mining, Svatá near Beroun
Abstract
The "Mapping of old impacts caused by mercury mining and its technological use in the Czech Republic" project is part of the "Environmental impact of mineral mining" project carried out in 2007-2009. It focuses on verifying the extent of possible contamination of soil with mercury, and on evaluating of the type of Hg bond in soils in the immediate surroundings of the abandoned mine near Svatá u Berouna. Systematic sampling of soils and stream sediments was carried out in the area of interest in 2008. Results of the total Hg content determined in the soil samples show that the amount of mercury in individual soil samples does not exceed recommended limit values of moderate contamination for medium-heavy soil (0.26-1 mg.kg-1). Lower Hg values determined in the humus layer (0.56 mg.kg-1) indicate that mercury probably does not bond to organic matter.
