Abstract
The aim of the study was to investigate and compare the heavy metals (Cu, Pb and Zn) concentrations in Festuca rubra of three groups of grassy ecosystems with different anthropopressive risk (A ecosystem - urban soils, B ecosystem - rural soils, C ecosystem - roadside soils). The strongest pollution was recorded for grass of A and C ecosystems. They were caused mainly by the presence of Pb which their concentrations significantly exceeded critical values for plants confirming unequivocally the inflow of metals from anthropogenic sources typical for areas with a high degree of industrialization and sources related to the automotive industry in A and C ecosystems. The concentrations of this metals fluctuated at the level of natural concentrations in plant B ecosystem indicating the lowest bioaccumulation. The average values of Cu, Pb and Zn the above-ground part of in the grass changed in the following order:
