The Přibram region belongs to the most polluted areas in the Czech Republic. Atmospheric deposition of potentially toxic elements from lead smelter represents the main source of contamination in this region. In this study, the most polluted location intensively used for agriculture situated northeast from the source of contamination was investigated. The individual sampling points were positioned by GPS and representative samples were taken from 0–60 cm split into three 20 cm layers. In the soil samples total Pb and Cd contents, plant available contents of these toxic elements and soil pH were determined. The total Cd content at the investigated site reached up to 13 mg/kg and Pb up to 2500 mg/kg in the top layer. The concentration of both elements decreases with depth and in the 40–60 cm layer the maximum content of only 6 mg Cd/kg and 400 mg Pb/kg was found. The plant available the content of Pb and Cd in the soil is related to the pH value. The correlation coefficient of exponential regression for Cd is –0.799 and for
