Heavy metals such as lead (Pb), cadmium (Cd), nickel (Ni), zinc (Zn), copper (Cu) present in large amounts in soil surface horizons are chemically stable compounds. They are complexed with various organic or inorganic ligands, which amplifies their toxicity. They, as we know, produce negative effects in different plant organs, and by transfer in the food chain produce different pathologies in animals and humans. The aim of the present work was to determine the transfer factor of lead (Pb) and cadmium (Cd) from soil to crop plants based on the concentrations determined for these elements. The transfer factor (TF) values were calculated for lead (Pb) and cadmium (Cd). Thus, the transfer factor for Cd was much higher than that for Pb, but the values do not exceed the reference value, namely 1.
