Direct and Indirect effects and the Long-term Risks of Air Pollution on Forest Ecosystems: Air Pollutants and Tree Ecophysiology
1993
Matyssek, R. (Swiss Federal Institute for Forest, Snow and Landscape Research, Birmensdorf (Switzerland))
The potential effects of long-term exposures to widespread low but raised concentrations above natural levels in Central Europe are still being discussed. This uncertainty results from an inadequate mechanistic understanding of the influence of air pollutants and other environmental factors of trees.

Depending on their concentrations, air pollutants are dangerous to forests. With the exception of some industrial areas in the east, concentrations of air pollutants in Central Europe are below the damaging threshold as shown by the records of the monitoring stations.

1993
Bues, C.T. | Schulz, H. (University of Munich, (Germany))
The results of numerous investigations in Europe on potential relationships between forest decline caused by immissions and the wood quality of diseased trees consistently showed the technical properties of wood form diseased trees to be unaffected. Wood from diseased trees can be used without reservation.

Innes, J.L. (Swiss Federal Institute for Forest Snow and Landscape Research, Birmensdorf (Switzerland))
Considerable uncertainty has surrounded the relationship between forest growth and forest declines in Europe. Although growth decreases have been recorded in several years, by the end of the 1980s, increment at many sites had reached a level higher than any previously recorded. Fertilization by carbon dioxide, favourable climatic conditions and better stand management may all have contributed.
