ResumoAbstract An extensive monitoring campaign was conducted between November 2011 and July 2012 at schools, homes, offices and Regional air quality network stations in Rome, within the LIFE+ EXPAH Project. This study allowed to improve the knowledge of actual concentrations and percent composition of Polycyclic Aromatic Hydrocarbons (PAHs) over the city area. High concentrations of all PAH congeners were observed during winter colder periods, e.g. benzo[a]pyrene weekly average concentration reached 3.0 ng/m3, while much lower values were recorded in summer (
