Screeningová analýza toxických kovů v říčních sedimentech Moravského krasu

The diploma thesis dedicates the presence of toxic metals in the river sediments of the Moravian Karst. Thesis assesses potential sources of toxic metals and deals with the issues of legislative measures relating to the presence of toxic metals in sediments. In the practical part diploma thesis determines the amount of toxic metals in 20 selected localities together with other geochemical parameters. pH, redox potential and conductivity were monitored in water. The amount of total organic carbon (TOC) and amount of toxic metals is determined in the river sediment. The concentration of toxic metals in sediments was determined by non-destructive X-ray fluorescence analysis (XRF method) on the device Niton XL3t GOLDD +. Finally, the measured results of toxic metals are evaluated and compared with valid legislative regulations
