Abstract: The CAMx chemical and transport Eulerian model has been applied over a domain focused on the Milan area (Northern Italy) for the whole 2004, on the basis of CityDelta III project input data set. Model results have been analysed by mean of the Source Apportionment technique at the Milan receptor. A quantitative analysis of the main processes governing the Secondary Inorganic Aerosols (SIAs) production showed that the overall efficiency of the transformation processes is influenced by several factors, which prevents defining simple relationships between emissions and secondary aerosol compounds.
