Soil and grass samples were collected in October 2009 within the Marcinkowski’s Recreational Park (MRP) of the city Poznań. Thirty six soil samples were collected at two depths (i.e., 18 samples at 0-10 cm and 10-20 cm) and additional grass samples (18). Pseudo total amounts of Pb, Cd, Cu and Zn were extracted by 6 mol HCl per 1 dm3; the same metals were also assayed in grass samples. These data were used for calculating soil-plant Transfer Coefficients (TC) and Plant Pollution Index (PPI). Results dealing with soil properties showed a downward homogeneity, a fact stressing on the strong impact of urbanization. High levels of silt and clay as well as organic carbon were decisive in shaping the size the buffering capacity, which in turn may have been fully controlled by the alkaline pH, ca 7.3. Amounts of Cd and Pb exceeded ca 9 and 6-fold, respectively the background values, whereas for Cu and Zn, ca 3-fold. The occurrence of such relatively high levels of Cd and Pb could be attributed to the impact of heavy traffic. Values of TC and PPI followed the sequences (based on means): for TC: Cd > Zn > Pb > Cu, and for PPI: Cd > Pb > Zn > Cu. Among all investigated metals, Zn contributed the most to the whole contamination of grass growing within the park. The influence of Pb and Cd was less pronounced.
