The phytoremediation effectiveness of heavy metals contaminated soils in the area of Upper Silesia was assessed on the basis of its real quantity in biomass harvest per 1 ha. The content of each heavy metal was compared with its quantity in the fraction of mobile and total value in horizon till 20 cm depth. The content of Zn uptake in carrot or parsley harvest (leaves and root) did not exceed 2.5% of its quantity in mobile fraction and 0.05% of its total content. The Cd and Pb values amount: 2.41%, 0.1% and 1.47%, 0.01 6%, respectively.
