The objective of this paper was to evaluate the transport of inorganic elements in soil and to create a map of soil potential to immobilize/transport these risk elements. The categorization of these risks was realized in two layers, contamination and potential soil sorption. The level of contamination was evaluated according to the Slovak Soil Law. Potential sorption of soil (PSS) is formed by qualitative (soil reaction, pH value, optical value of soil humus) and quantitative factors (C, H-depth of humus horizon); it was evaluated according to the equation as follows: [PSS] = F(pH) + F(Q46) + F(Corg) x F(H). The map of soil immobilisation potential was created by the fusion of both the contamination layer and the layer PSS. It shows the distribution of five categories of risk elements immobilisation potential. Soils with very low immobilisation potential are reported predominantly in the regions of Kosice and Banska Bystrica where soils are contaminated by geochemical anomalies and anthropogenic sources. Transport is a reversible process to immobilisation; thus, the highest level of immobilisation potential is identical with the lowest transport category.
