【 摘 要 】

This paper provides a comprehensive assessment of four sites of roadside bog. The study was conducted at a distance of 20, 70, 120, 170 m from the road. Changes in the top layer of peat deposits and the current vegetation were detected at sites less than 120 m from the road. The results obtained showed that Zn and Cu were concentrated in plants at a distance of 120 m from the road, and that the Cd and Pb contents were highest at 70 m from the road. At 20 m from the road, the concentrations of all elements except Pb were at the background level. Proximity to the road increased the ash content of peat and reduced the biogeochemical activity of marsh plant species.
