| Title : | BIOMONITORING OF ATHMOSPHERE AIR POLLUTION IN THE FOREST ECOSYSTEMS AND ECO-TONE ZONE |
| Abstract : | Within our research, the air quality of 62 forest ecosystems from Republic of Moldova was assessed, taking into consideration the lichens indicator species specific diversity, abundance and toxitolerance. It was established that the Moldavian forest ecosystems do not contain reserves concerning critical loads for SO2 pollution, the annual average for the vegetation season for dendrological species being 0,02 mg/m3 air, and for communities of lichens and cyanobacteria, organisms sensitive to pollution, represented only 0,01 mg/m3. Lichen indication demonstrated that the current level of pollution is between 0,05 and 0,5 mg/m3 SO2 air, thus long-term harmful effects are manifested in all 62 studied forest ecosystems and the ecosystems from the eco-tone zone. We believe that for the Republic of Moldova lichen, indicator species can provide a scale of 6 levels: 5 levels characterized by species with different toxitolerance degree and the last step being an area in which lichens are completely missing, thus the most polluted area. Within the Republic of Moldova territory, there were reported 3 forest ecosystems in which the air is evaluated as clean air, 11- low polluted air, 31- moderate polluted air, 12- polluted air, 3- high polluted air and those with critical polluted air was missing. |
