Abstract (in english)
   The Lysina catchment is a forested area that is extremely susceptible to adverse impacts from acidic atmospheric deposition. It is underlain deficient, podzolized brown forest soils and peaty gleys. The most striking feature of the Lysina stream is an extremely high concentration of total aluminium (weighted mean 68 Šmol l-1 or 1.84 mg l-1). Monomeric inorganic Al is the dominant fraction present primarily contains free Al3+ and fluoro-complexes. The organic monomeric aluminium fraction is only about 15% of total monomeric Al. Surface runoff os dominated by sulphate (84% of anion equivalents) and silica, accompanied by high concentrations of H+ and Aln+ (ń40% of cation equivalents). Stream-water acidity increases during flood events and some of the increase is associated with the mobilization of organic acids. The input of sulphur to the catchment is 26.3 kg ha-1 year-1 (combination of bulk precipitation and throughfall) and output 28.3 kg ha-1 year-1 (runoff).
   The critical load of sulphur for adversely impacting surface water was estimated at 1 kg ha-1 year-1
