Scavenging of air pollutants during precipitative events at a natural coastal ecosystem

The 'Pineta di S.Vitale' (Ravenna) is a 800 hectars ecosystem located along the Adriatic coast in northern Italy. The historical and landscape meaning of this natural ecosystem belongs to the Italian cultural heritage and the forest has been cited in the Dante's Divine Comedy. The woodland as well the neighbour wetland areas are located in proximity to petrochemical and power plants which influence the trace gas concentration levels, expecially under such typical circulation phenomena as winter 'bora' and the anticyclonic spring-summer conditions. Rain samples collected for one year during single precipitative events have been analysed in order to define the scavenging mechanisms of pollutants by hydrometeors and the role of the local air quality and meteorology in the wet deposition patterns at the surface.
