Abstract
In the last decades, few days a week, several city centres in Italy are closed at vehicular traffic in order to limit the presence of particulate matter, often exceeding the limits set by law [1,2]. The particulate matter have an impact on hu- man health [3,4], in the cultural heritage and natural environment deterioration [5,6]. Many studies have been the car- ried out in air monitoring in urban areas while the targeted surveys to assess the impact on air quality of snow disper- sion for ski activities are rare. Thanks to the Autonomous Province of Trento it has been possible to sample the snow- pack in some ski areas in Italy and thanks to stratigraphic profiles it has been possible to observe variations of the chemical composition over time. Natural contribution is strictly related to winds and currents movement, for this reason a deep knowledge of these factors can help in the determination of the prevalent trajectories during the year [7,8]. Dur- ing a penetrometeric and stratigraphic profile on Presena glacier, the main nivo-meteorological features, air temperature and temperature inside the different layers of the snowpack have been measured. Some snow samples has been col- lected and analyzed by SEM-EDS, ICP-MS and IC. These qualitative and quantitative analyses allow to obtain chemi- cal and mineralogical composition to define the emitting source.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
