The aim of the research was to evaluate the influence of the metallurgy-sulphur railroad (LHS) on some soil properties of the Roztoczański National Park. Special attention was paid to sulphur risks, due to sulphur transport that way, although in smaller quantities as compared to the previous decade. The study was based on the analysis of basic properties of selected soils and content of total and sulphate sulphur in soil samples taken in 2 cross-section profiles, located 400 and 900 m from the border of the Park and 50, 100, and 150 m from the rails; from 3 levels of forest soils: litter, 0-10 cm, and 30-40 cm. Pedological survey indicated that within the study area predominated light soils. They are derived from river sands (mainly gley, gley-podzolic, podzolic soils, and black earth), and contain low amounts of the fine fraction. It was found that the line, which runs across the protected areas of the national park. does not exert nowadays a direct negative influence on the investigated soil properties (C-organic, reaction, mobile aluminium). The amount of total and sulphate sulphur remains on the level characteristic for such soil types in natural environment. No decrease in the content of both forms of sulphur was found along with the distance of sampling points from the LHS rails.
