Dredged Material Quality in Anthropogenically Exploited Catchment Area

Abstract:

The paper is focused on the research of pollutants in dredged material and water in the watershed of the Sigord reservoir (Eastern Slovakia), which is influenced by anthropogenic activity. The monitored area extends to the cadastral area of ​​Zlatá Baňa, which has been used for a long time and intensively for mining of gold, antimony and mercury. After the end of mining activities (at the beginning of the 20th century) the territory remained devastated by numerous remains of mining activities and no attention has been paid to this area in terms of scientific research. Therefore, the monitoring of dredged sediment and water quality has been carried out. The results show that the limit values ​​of selected heavy metals (such as Sb, As, Hg, Pb, Cu, Zn, Ni, Fe and Al) are exceeded in both sediments and water in the reservoir watershed, as a result of the former mining activities around Sigord.
