| Summary: | The objective of this paper is the ambition to elaborate a system of evaluating the potential transport risk of inorganic risk elements, cadmium and lead, and of creating maps of the soil potential for the immobilisation of these risk elements. The categorisation of the potential immobilisation of cadmium and lead was realised on the basis of two layers, the layer of metal concentration (Cd or Pb) and the layer of potential soil sorption. The level of metal concentration was evaluated according to the Slovak Soil Law. The potential soil sorption (PSS) of cadmium and lead is defined by qualitative parameters (soil reaction - pH value, optical parameter of humus quality - Q46) and quantitative factors (Corg, H - depth of humus horizon) and was evaluated according to the Eq.: [PSS] = F(pH) + F(Q46) + F(Corg) × F(H). On the basis of this rating, maps of categorisation of cadmium and lead potential immobilisation were created. These maps of the soil immobilisation potential show the distribution into five categories of Cd and Pb potential immobilisation. |
