In the European continent most of experimental data related to the dry deposition of pollutants have been obtained in northern countries. Thus, it is necessary to verify experimentally if extrapolations derived from those data apply to southern European conditions, where summers are drier and the vegetation has a different seasonal cycle. In this perspective, the University of Aveiro carried out field studies on ga
