Soil is one of the most important sources of plant foods’ contamination by heavy metals which enter into human and animal organisms via the food chain. From the observed metals (Zn, Cu, Ni, Pb, Cd) the enhanced total contents of Cd and contents of mobile forms of Pb were determined. Especially mobile forms of Pb in soil (0.100-0.295 mg∙kg⁻¹), higher than the critical value, represent a risk resulting in the high content of Pb in potatoes (0.244-0.855 mg∙kg⁻¹ FM). The high significant correlations between soil and potatoes in values of Pb content and were between soil pH values and Pb content in potatoes were confirmed in two from three potato cultivars (P-value < 0.01). No correlation was confirmed between humus content in soil and Pb content in potatoes.
