KONTAMINÁCIA VYBRANÝCH ZLOŽIEK ŽIVOTNÉHO PROSTREDIA VPLYVOM STARÝCH ENVIRONMENTÁLNYCH ZÁŤAŽÍ
Journal Title: FOLIA GEOGRAPHICA - Year 2013, Vol 50, Issue 2
Abstract
Safe and good quality groundwater is the basis for the environmental quality and human health. Polluted waters may become the source of undesirable substances which can penetrate to the other environmental components. Former mining areas, where metal ores were long-time mined and processed represent the most polluted areas by heavy metals in Sloviakia. Study aims to determine the content of heavy metals (Cu, As, Pb, Fe, Hg) in Rudniansky creek, which flows through the environmentally loaded and unhealthy former mining area and describe the flora diversity along the creek. Some chemical (pH) and physical (water conductivity, oxygen saturation) water properties were also evaluated. Above the limit values of copper and mercury were determined on the localities close to the tailing pond and mercury processing plant as the result of insufficient security. Plant species composition indicates the presence of toxic elements, what result in the occurrence of the species resistant for heavy metals as: Calamagrostis epigejos, Arctium lappa, Cirsium rivulare, Geranium palustre.
