Abstract
Runoff and atmospheric chemistry in the Krusne hory Mts. have changed significantly from 1978 to 1994. Forest die-back related deforestation resulted in decreased dry deposition of SO2 and changes in streamwater chemical composition. Atmospheric sulphur (S) deposition decreased from extremely high values of 66.6 kg S ha−1 year−1, in the early 1980s to 35.5 kg S ha−1 year−1 in 1994. Decreasing S input is reflected in decrease of streamwater sulphate (SO42−) concentrations, which decreased from 1560 μeq l−1 to 1164 μeq l−1. Runoff export of S was 53 kg S ha−1 year−1 in 1993, S is not retained in the catchments. Nitrogen (N) budget indicates accumulation in the catchment, which is attributed to forest regrowth.
