Abstract

Research was aimed at detection of actual state of contamination throughout monitored indicators – heavy metals and pH values in soil samples of model area of the Nitra river. It analyses and evaluates recorded values of determined elements and soil pH, and following comparison of these values with limit values of current effective legislation. In the inundated area of the Nitra River, we evaluate concentration contents of heavy metals: As, Co, Cr, Cu, Hg, Ni, Pb, Zn by way of appropriate analytic methods (dissociation in aqua regia) and pH values in KCl solution. In our area of interest, based on the soil samples analysis, contamination of following elements Cd, Cr, Ni, Pb was found. Based on gained results and available knowledge we identify the most probable origins of contamination and we also design measures for improvement of recent state.
