APLICAREA UNOR METODOLOGII EUROPENE ELABORATE ÎN CADRUL PROGRAMELOR CONTINENTALE ÎN CERCETĂRILE ECOLOGICE DIN MOLDOVA

Abstract

The monitoring of the state of the environment carried out in the Republic of Moldova by means of non-instrumental (bio-indication) and instrumental (analysis/analytical) methods ap plied in European programs allowed to obtain some parameters compatible with those of other countries and which are included in the continental databases. Thus, based on the spatial distri bution of SO2 in the atmospheric air, established on the basis of bioindication, we find that it di ffers greatly from that indicated in the same 32 cells (50x50km) of the European EMEP program, the main reason being the low elevation and the fragmentation of the forests and the rugged relief, fact that allowed us to propose the reduction of the cell surface. It performed a comparative analysis of throughfall atmospheric deposition in the Repu blic of Moldova to that determined in the intensive (level II) forest monitoring plots in Europe. Monitoring ions S-SO4 2-, N-NO3 - și N-NH4 + was carried out according to the methodology re commended by the International Co-operative Programme on Assessment and Monitoring of Air Pollution Effects on Forests (ICP Forests). Throughfall deposits of mineral ions recorded in forests studied in Republic of Moldova are comparable to deposits recorded in the central and central-eastern European regions.
