The objective of this paper is to elaborate a system of evaluation of potential risks of transport of inorganic elements, and to create a map of soil potential to immobilisation/transportation of potential 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 (C46) + F(Corg) × F(H). The map of soil immobilisation potential was created by fusion of contamination layer and layer of potential sorption of soil, and shows the distribution of five categories of risk elements immobilisation potential. Soils with very low immobilisation potential are reported predominantly in Košice and Banská Bystrica regions, 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.Keywords:inorganic contaminants; contamination; immobilisation; transport; soil properties
