Contamination of the Burňa watercourse, by a dumps complex

Abstract

This article dealing with the problematic contamination surface water in dumps complex and there were monitoring basic physical and chemical parameters, toxic and strategic metals. There were analysed inorganic ions NH4, Cl, SO4, NO3, NO2 by standard laboratory analysis, and the elements Pb, Cd, Cr, Cu, Ni were measured by method ICP MS, and elements Zn, Fe, Mn, Na by method AAS. The case study of the contamination in the Burňa watercourse basin, in industrial landscape of the Ostrava city is unique in solving the problem of ecological burdens of the Ostrava city. One year of monitoring case study showed a significant load on the watercourse with the expected contamination especially by toxic metals. The surface water Burňa watercourse was affected by a dumps complex and their chemistry. The source of the contamination is the impact of former mining, in this post-mining landscape.
