<abstract xmlns="http://www.w3.org/1999/xhtml">Soil is one of the most important environmental backgrounds, as it
provides water and nutrients for plant production. It is the starting
point for the entry of heavy metals into plants and then into the
food chain. Of risk elements studied (Zn, Ni, Cd, Pb), we found
increased Cd and Pb content in the soil extract by aqua regia and
NH4NO3, respectively. More than twofold content of Pb mobile
forms (0.218 mg • kg-1 ) resulted in enhanced Pb content in tubers
of all three potato cultivars: cv. Volumia 0.404, cv. Cicero 0.580 and
cv. Mozart 0.638 mg • kg-1 FM. In all investigated cultivars, highly
statistically significant differences in content of Pb between studied
potato cultivars (P-value&lt;0.01) were confirmed.</abstract>
