Abstract

Trace elements, including elements with a negative impact on the environment, are a natural part of the lithosphere. However, with increasing industrialization, there is an uneven spatial distribution and an extreme increase in the concentration of these elements in the environment. It affects their content in the soil-plant system content. The aim of the paper is to define the content of risk elements in the soil profile to determine the level and origin of the soil contamination. The soil sampling was conducted in two agricultural sites with a different degree of contamination. The samples were taken at each site from a depth of 0.10 to 0.70 (0.80) m at each site. The soil pH, humus content and total content of the selected elements (Cd, Cu, Pb, and Zn) were analyzed. The results showed that the pH values of the studied sites varied, but the content of organic matter had a similar trend. The content of the studied elements differed significantly in the sites. The first site (Suche Luky ? SL) is located at the floodplain of a river that drains a historical mining area. Therefore, the soil profile formed by the alluvium is more evenly contaminated compared to the second site (SM-01) located in an area that has not been exposed to long-term contamination. However, the topsoil layer of the second site is characterized by a higher content of the studied elements compared to subsoil layers. It is probably due to the regular use of fertilizers and chemicals in the topsoil layer.
