Dureckova, E. (State Nature Protection of Slovak Republic, Nitra (Slovak Republic). Protected Landscape Area Ponitrie)
Since 1990 the investigations of quality of some components of nature environment were carried out on selected permanent plots in Protected Landscape Area Ponitrie focused on pollutant contents. The increased concentration of pollutants in precipitation from the top of the Vtacnik Mts. indicates firstly the effect of the nearby thermal power station, secondly documents an increased immission load on forest ecosystems in ridge positions of these mountains
Afficher plus [+] Moins [-]The response of the forest ecosystem to the reduction of TPP SO2 emissions with emphasis on the nutrient cycling

Simoncic, P. | Kalan, P. | Kraigher, H.: Levanic, T. | Urbancic, M. | Vilhar, U. (Slovenian Forestry Institute, Ljubljana (Slovenia))
Selected parameters of the nutrients cycling process for forest ecosystem were investigated in period 1989-2000 at Prednji Vrh in the area affected by the Sostanj thermal power station. In the year 1995 desulphurization of exhaust gases from the TPP Sostanj caused considerable reduction of SO2 emission. We could not find serious tree-ring width decline in spruce. In the year 1956 and 1978 tree-ring widths rapidly declined. In the year 1995 slight icrement recovery could be observed. One probably climatically (drought) induced pointer year (1992) occurred
