Abstrakt (anglicky)
   The identification of heavy minerals and their relative proportions enabled to assess the extent of contamination of stream sediments and also the character of individual sources of contamination. No extensive dissolution of copper and cobalt minerals in stream sediments takes place due to the neutral or slightly alkaline character of surface waters in the area. However, occasional accidents in chemical plants processing copper and cobalt ores result in short-term but sharp increase in acidification of surface waters which consequently leads to the dissolution of heavy minerals and to sharp increase in copper contents in these waters.
