Effects of H2O2-Containing Acidic Fog on Young Trees

摘要

The influence of air pollution on forest die-back in Central Europe is not clarified satisfactorily. Both the #x2018;acidification-theory#x2019; and the #x2018;ozone-theory#x2019; as well cannot satisfactorily explain the die-back to its full extent. Some researchers try to link damage patterns to occurrence of fog and ground-based clouds, but laboratory experiments have failed to show serious effects of fog water on trees caused by acidic compounds. The role of reactive compounds such as H2O2, has been overlooked so far.
