Abstract (in english)
   Sulfur input/output mass budget were measured in two spruce die-back affected catchments in Northern Czech Republic over a period of 4 years (1994-1997). We used stable isotopes (34S/32S) to investigate whether the extra sulfur in surface dischargecomes from bedrock, or represents delayed release of S which accumulated in the soil during the peak-pollution period of 1960-1985. Bedrock S was isotopically too light to supply all excess S in discharge.The constructed S isotope mass balance indicated that only 2,5 and 12%,respectively, could be derived from the bedrock. Most of the exported S was of antropogenic origin.
