Research was carried out in the Roztoczański National Park on podsol soils to examine the content of heavy metals: zinc, copper and chromium near the Metallurgical-Sulphuric Line (LHS) and near the expressway (DSR). The research covered two protected areas in the Park: Area 224 “Obrocz” within the range of influence of LHS and Area 341 “Florianka” within the range of influence of DSR. Samples for analysis were taken from Ah horizon and Bh horizon, without preserving the natural structure, from the distance of 10 m and 50 m from LHS and DSR. In the samples we determined the granulation, pH and the content of heavy metals: zinc, copper and chromium. The research proved that the soil samples taken from both of areas are characterized by low content of floatable and colloidal fractions. The dominant fraction is sand. The analysis of pH showed that all examined soils have acid reaction. A decrease in the content of the examined heavy metals was observed in relation to increasing depth and distance from the Metallurgical-Sulphuric Line and the expressway. The total content of the general forms of zinc, copper and chromium in the examined samples is within the limits of their natural content, therefore, it can be assumed that the examined areas are not contaminated by the mentioned metals.
