Investigation of the Large-Scale Impact of Air Pollution Components on Forest Ecosystems in Bavaria

摘要

Typical mean distributions of pollutant concentrations were obtained on the basis of large-scale distributions of concentrations of SO2, NOx, ozone, and of acid-forming paticles over Bavarian forest damage areas measured by aircraft and vehicle. The impact of polluted fog on the forests in the Fichtelgebirge was investigated. The results show that no direct damaging effects of the SO2 and NOx gases can be detected. However, serious forest damage exists in the areas having the highest mean ozone concentration levels. It is not possible to establish a clear correlation between polluted fog and forest damage.
