The research was conducted in order to determine the catalase, dehydrogenase, and arylsulfatase activities of soils exposed to transportation pollutants. The research ma-terial consisted of soil samples collected from points located along road no. 957 at a section passing through Zawoja (the Malopolska Region), from places at a distance of 5 and 200 m from the road edge. The samples were collected from a 0-10 cm layer, from areas covered with grasses. No considerable diversification in the enzymatic activity of the soils, depending on their distance from the road edge, was found. The mean activity of catalase and dehydrogenases in the soils located 5 m from the road edge was, respectively, 4 and 7% greater than the activity of the soils located 200 m from the road edge. The mean arylsulfatase activity in the soils located 5 m from the road edge was 3% lower than in the soils located at a distance of 200 m. A positive correlation was found between the catalase and arylsulfatase activities, and the dehy-drogenase activity in the soils. [ABSTRACT FROM AUTHOR] |
