  Rezumat:  Historical data for Europe show increasing emissions, and consequently deposition, of sulphur, up to a factor of 2 in 1950 and 3.5 in 1980 in comparison to pre-industrial levels (Posch et al., 1996). Attention now focuses on global environmental issues, in particular on the contribution on European emissions of precursors to climate changes. There are no known methods besides sulfur isotope abundance ratio measurements used to investigate the fate of anthropogenic sulfur in the environment. The stable isotopes sulfur composition in compounds of anthropogenic origin, present in atmosphere, biosphere, hydrosphere, groundwater, soil, etc., may differ from those originating from natural sources. The sulfur cycle plays a key role in the hydrochemical development of lignite and coal mining districts. Identification of sulfur sources and transformations is essential to investigation of pollutants in the mining areas. Sulfur isotope ratio can be treated as an environmental tracer, and may be applied to study the sulfur pollution distribution from coal mining and combustion processes, in the environment.
