In the concluding consultation of the symposium "Acid Deposition, a problem for Europe" held in Karlsruhe in September 1983, Dr. GINJAAR, the previous Minister of wellbeing and fitness and Environmental security of the Netherlands, emphasized the necessity for establishing a concerted study programme together with the results of pollution on terrestrial and aquatic ecosystems. The Council of Ministers of the eu group in 1984 followed a revision of the third group Programme on atmosphere comprising agreement examine and concerted motion within the box of the consequences of pollution in eco­ platforms. those examine parts have been additionally brought within the 4th R-D group Programme on surroundings, followed through the Council of Ministers in 1986 and are topic back to agreement study and concerted motion. The fee of the eu neighborhood is particularly involved to extend the effectiveness of researcn tasks conducted in the nationwide programmes, and people undertaken on the neighborhood point. The fee has a tendency to enhance an built-in medical procedure, together with not just the physico-chemical behaviour, the shipping and the deposition of airborne pollution but additionally the consequences of those pollution, particularly on dwelling organisms and ecosystems. in regards to the categorical factor of the results, the fee is attempting to improve and boost a multi-disciplinary method associating biologists, pathologists, eco­ physiologists, and experts of soil sciences, in the concerted motion, in addition to inside coordinated study projects.

Je ne voudrais pas ici anticiper les resultats du Symposium que mes collaborateurs, qui ont participe a des reunions de travail et des sessions specialisees, m'ont indique representer des progres importants. II me semble possible de prevoir que les mecanismes complexes d'action des polluants puissent se ramener a quelques principes fondamentaux et que nombre des theories emises au debut ne jouent qu'un role secondaire. L'etablissement de relations quantitatives reste encore a faire. II existe d'autres besoins de recherche.

Ceci est une importante condition pour comprendre les symptomes des degats. Nous avons encore beaucoup de travail devant nous. Nous ne devons pas nous decourager de ce que l'interet du public pour la pollution atmospherique, autrefois evident, diminue quelque peu. En relation directe avec les debats sur l'energie nucleaire, il est -9- indispensable de faire une evaluation approfondie des consequences de l'utilisation des combustibles fossiles. Je dois vous remercier, vous Monsieur Ie Ministre et tous vos collaborateurs, pour la peine que vous avez prise et Ie travail necessaires a la realisation de ce Symposium avec la Commission.

5. , 1980; Thompson, 1981; Postel, 1984). Much less is known about effects of regionally dispersed airborne chemicals such as ozone or acid deposition (Pinkerton, 1984). Although nearly 20 regionally important cases of change in condition of forest trees have been reported in Europe and North America (Cowling, 1986), in only a few cases are airborne chemicals considered probable or possible causal or contributing factor. Some of the most important cases are described below in order of decreasing quality of evidence that airborne chemicals may be involved.
