Concentrations of zinc, cadmium and lead in ionic forms and in forms bound to humic substances isolated from ground and surface waters of drainage catchment were analysed. Higher total concentrations of examined metals were found in ground waters as opposed to surface waters. Particularly clear difference was observed in case of cadmium. Mean concentrations of cadmium in ground waters amounted to...
