Determination of Local Source Profile for Soil Dust, Brake Dust and Biomass Burning Sources

Knowledge on the main emission sources and their relative importance is essential for policy makers to define effective pollution reduction strategies. Such knowledge can be gained by receptor modeling using e.g. the chemical mass balance model (CMB). For a successful application of CMB all important sources must be known and information must be available on representative emission profiles. Speciation profiles of emission sources can be found in literature and extensive databases are available (U.S. E.P.A., 2002). However, it is preferable to use profiles representing the actual sources present in the area whenever is possible. For the Lombardy region, previous studies have demonstrated the importance of soil and fugitive dust, biomass burning and brake lining dust (Regione Lombardia, ARPA Lombardia, Fondazione Lombardia per l¿Ambiente, 2008; AA.VV., 2006). The goal of this work is to report our methodology used to determine ¿local¿ source profiles of soil dust, domestic wood burning and brake lining dust, to be used for example in the CMB applications. To investigate the model sensitivity, simulations were carried out for several sites with different local and no-local profiles.
