Distribution of water extractable heavy metals (Cd, Co, Mn and Mo) in the topsoil of Osijek- Baranja County (Eastern Croatia)

Based on the pedological map of Osijek-Baranja County in eastern Croatia 74 soil samples were collected and analyzed for water extractable heavy metals(Cd, Co, Mn and Mo). By using GIS technique (ArcView software), different set of maps showing the water extractable metals were created. The maps indicate the correlation of water extractable fraction of heavy metals with soil pH, further statistical analysis will be preformed to confirm these assumptions. In addition analysis of variance was conducted to examine the influence of land use and different soil types on water extractable metals. Land use has shown significance for Cd, Co and Mn while soil type for Mo. These results also seem to be pH dependent, as land use and soil type differ in pH which is the factor causing the difference in the concentration of water extractable metals.
