摘要：

Sulphur isotope compositions were determined in two different Polish coals ( hard coal and lignite) and by-products originating from their combustion. The desulphurization process was also investigated. It was demonstrated that desulphurization changes the isotopic composition of sulphur emitted in the form of SO2 to the atmosphere even if the process is conducted in a different way ( wet lime technology and electron beam method). This fact has to be considered in the studies regarding anthropogenic sulphur genesis and its fate in the environment.
