Abstract

It performed a comparative analysis of throughfall atmospheric deposition in the Republic of Moldova to that deter-mined in the intensive (level II) forest monitoring plots in Europe. Monitoring ions S-SO42-, N-NO3- şi N-NH4+ was carried out according to the methodology recommended by the International Co-operative Programme on Assessment and Monitoring of Air Pollution Effects on Forests (ICP Forests). It was found that the atmospheric ions deposition mo-nitored in forest ecosystems in northern the country are reduced than deposits recorded in forest ecosystems in the center of the country, the latter being subject to increased risk of threat to the health of the trees and functionality forest ecosystems. Throughfall deposits of mineral ions (S-SO42-, N-NO3-, N-NH4+) recorded in forests studied in Republic of Moldova are comparable to deposits recorded in the central and central-eastern European regions.

Keywords: atmospheric pollution, deposition monitoring, forest ecosystem, mineral ions.
