【 摘 要 】

The deposits, located in Nová Ves and Zlaté Hory were well known and important sources of metal ore in Jesenniky region in the past. Especially the one in Nová Ves, which is recently the most important hydrothermal deposit of venous type in the whole area. The mining activity, aimed on lead and zinc minerals was practically permanent here from the middle-age to 1959. On the other hand, the site in Zlaté Hory is the most important ore deposit in Czech Silesia. The non-venous types of polymetallic, copper and gold deposits, evolved in the complex of metamorphic devon rocks are located on south and south-west directions of the area. Long and permanent mining industry caused remarkable changes in the local environment, creating mine heaps and depressions. The probability, that dump material contains potentially toxic substances that could be possibly leaked into surrounded environment is high. This contribution presents the part of complex study results, aimed on evaluating of potential environmental impacts in above mentioned locations. It aims on contamination, caused by potentially toxic heavy metals (Pb, Zn, Cu, Ni, Fe, Mn, Co, Cd, Cr and As) at the sites, exposed to mining activity in the past. The study focus on the contamination of these sites and evaluate them as potential risk for surrounded environment.
