Abstract

IMPACT OF SULPHUR EXPLOITATION ON GEOCHEMICAL FEATURES OF SURFICIAL ENVIRONMENT OF SULPHUR DEPOSITS FROM POLISH-UKRAINIAN BORDERLANDAbstract. Native sulphur exploitation leads to strong degradation of natural environment. Sulphur deposits like Basznia and Nemyriv occurring along the northern margin of the Carpathian Foredeep in the Polish-Ukrainian borderland were exploited using method of underground melting by hot water. The exploitation was stopped in the nineties. The sulphur mine areas are characterized by strong mechanical and chemical soil transformations. Geochemical analyses of soil and subsoil material reveal that the anthropogenic changed soils are distinctly acidic (mostly pH = 2–6) and enriched Ba, Ca, S and Sr compared to adjacent forest and agriculture grounds.
