Uptake of NH4 -N by streambed biota of mountain brooks was studied in the alpine zone of the High Tatra Mountains . Experiments were performed involving in situ dosing of ammonium directly to the acidified stream and incubations of ammonium and streambed bryophytes in enclosures within a range of pH from 4 .45 to 8 .10 .NH4 -N uptake length decreased with decreasing stream discharge, while comparable values of dischargenormalized uptake lengths were found during two in situ experiments .Maximum uptake rates of NH4 -N obtained during the incubation of bryophytes (6 to 11 mg m -2 h -1 ) were comparable with results of two in situ experiments (8 and 12 mg m -2 h -1 ) . The average NH4 -N uptake rates observed during incubations lasting 3 to 5 hours (4 .3 mg m -2 h-1 ) were not related to the pH of stream water. Nitrification of about 50% of the NH4 -N added was observed in non-acidified streams, but was negligible in acidified streams . Significant photoinhibition of nitrification was observed in non-acidified streams during enclosure experiments . 157

“…There are about 120 lakes of glacial origin in the Slovak part of the mountains, and these are mostly situated in alpine zone (1800-2200 m a.s.l.). This area receives acid deposition (annual weighted mean of pH is 4.2-4.5) with sulphate and nitrate the dominant anions (Cerovsky, 1983;Gazda & Lopaovsk2i, 1983;Moldan et al, 1987).…”

The chemistry of 53 lakes at various stages of acidification and inhabited (at the presence and/or in the past) by pelagic Crustacea was studied in September 1984. Ten of these lakes were investigated in detail biannually (July and October 1987-1990). The July results reflect the influence of snowmelt and were compared with the October ones. The most important anion was sulphate with the average values of 98 and 104 peq 1-1 in 1984 and 1987-1990, respectively. High concentrations of nitrate (21-56 Ieq 1-) were observed in lakes above the treeline. Mean relative composition of cations does not differ between July and October; small changes are in the mean relative composition of anions. Acidification of lakes, expressed as a decrease in alkalinity, is 100 /Ieq 1-, and is equal to the increase in the sum of sulphate and nitrate. The values of total phosphorus and COD are the lowest in the range of pH 5-6.5. Alkalinity, sulphate, nitrate and pH do not show any trend with time over the last ten years.

The knowledge of the importance of atmospheric matter input in ecosystems led—on an international scale—to intensive investigations of the atmospheric depositions, especially rainwater quality. On the basis of monitoring networks on local to global scales the spatial and temporal variations of the main and trace components in rain water were investigated. This paper based on data from the literature and from investigations in the GDR and especially in the district of Leipzig.
