This study presents the results of measurement of PAH (Polyciclic Aromatic Hydrocarbons) concentrations in the urban atmosphere in Milan. Analysis have been led on samples collected in two sites: the first representing the typical medium-urban traffic condition of the city (Messina Street), the second representative of high-level traffic pollution (a road tunnel near the Central Railway Station). Greater attention has been focused on the PAH content in the PM 2.5 rather than in the PM 10 fraction, as it seems this type of pollutant are mostly (80-90%) shared out in the fine atmospheric particulate matter. The association of PAH presence in different dimensional classes is compared to data collected by other studies found in literature. The daily trend of PAH concentration has also been correlated to the traffic volumes recorded in the sites. Furthermore, data on the principal inorganic compounds (sulfate, nitrate and ammonium) analyzed in the samples, and the description of their possible presence in the atmospheric paniculate matter is given.

Abstract
This study presents the results of measurement of PAH (Polyciclic Aromatic Hydrocarbons) concentrations in the urban atmosphere in Milan. Analysis have been led on samples collected in two sites: the first representing the typical medium-urban traffic condition of the city (Messina Street), the second representative of high-level traffic pollution (a road tunnel near the Central Railway Station). Greater attention has been focused on the PAH content in the PM 2.5 rather than in the PM 10 fraction, as it seems this type of pollutant are mostly (80-90%) shared out in the fine atmospheric particulate matter. The association of PAH presence in different dimensional classes is compared to data collected by other studies found in literature. The daily trend of PAH concentration has also been correlated to the traffic volumes recorded in the sites. Furthermore, data on the principal inorganic compounds (sulfate, nitrate and ammonium) analyzed in the samples, and the description of their possible presence in the atmospheric paniculate matter is given.
