Mercury contamination of top soil and plants in area of Veľká Studňa Hg-deposit at Malachov (Central Slovakia)

Midula, Pavol, 1989- Mercury contamination of top soil and plants in area of Veľká Studňa Hg-deposit at Malachov (Central Slovakia) / Pavol Midula, Ingrid Turisová, Peter Andráš. -- The study is focused on Hg concentration in soil of dump-field Veľká Studňa and its accumulation by selected plants, which consisted of the representatives of grass, herb and wood species. The study area was divided into several parcels, based on physiognomic features of plant communities. In the order to predict the Hg distribution for the whole study area, the interpolation methods were used in GIS. The plant material consists of 4 plant species: Calamagrostis epigejos, Lotus corniculatus, Leontodon hispidus and Picea abies. The samples were dried, grained, dissolved in HNO3 and HCl solution and consequently measured by inductively coupled plasma mass-spectrometry (ICP-MS) for Hg content. The results show a mass contamination of the dump environment by mercury. The values in soil variable from 16 to 910 mg.kg-1. The bioaccumulation potential of some plant species is also significant. The highest content of Hg was found in Picea abies ─ 24 mg.kg-1. With the regard to presented data, the dump-field could be considered as the risk for the local environment and its study is essential. The analyses of bioavailable forms of mercury in the soil samples are also considerable
