Experiments were carried out on soils derived from 12 park gardens situated in suburban zones or in city centres in areas of similar physiographic conditions exposed to direct anthropogenic influence. Investigations were performed within administrative boundaries of the following towns and cities: Krakow, Lublin, Miasteczko Slaskie, Szczecin, Zabrze and Zamosc. Soil sorption properties and levels of enzymatic activities in the examined park gardens fluctuated widely and distinctly depended on their location. In soils of park gardens situated in suburban areas, values of sorption capacity and level of saturation of sorption complexes with bases were several times lower, whereas the activity of the examined enzymes (dehydrogenase, acid phosphatase, alkaline phosphatase, urease and protease) was several times higher in comparison with the soils situated in town centres indicating a differentiation in the ecological systems in central and suburban city areas
