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...
A procedure for determining the chemical forms of zinc, cadmium, lead and copper in surface and ground waters located in Agricultural Landscape Park (ALP) is outlined. Heavy metals were differentiated into ionic, labile forms and moreover on stable complexes and chelates. In the studied waters, concentrations of ionic forms were 17.9-45.2 μgZn/l, 0.003-0.038 μgCd/l, 0.28-6.29 μgPb/I. Labile complexes...
Heavy metals migrate in thc environment in different forms (free ions, labile inorganic and organic complexes). Most of the heavy metals create a potential threat to organisms. Their harmfulness is connected not only with biological, biochemical properties, but also depends on forms in which heavy metals appear in the environment, so-called speciation. The chemical term speciation has several meanings...
The concentrations of dissolved organic compounds (DOC) in the waters of small and large agricultural drainage basins were analyzed. It was found that the average DOC concentrations in surface water of the large agricultural drainage basin was 15.6 mg/1. Much higher DOC concentrations were noted in ground and surface waters of the small agricultural drainage basin. Groundwater under a cultivated field...
