Carcinogenic and mutagenic risk associated to airborne particle-phase polycyclic aromatic hydrocarbons: A source apportionment

► Eleven particle-bound PAHs were monitored for one year in an urban site. ► A receptor model was used to detect the main PM emission sources. ► Sources of carcinogenic and mutagenic effects were also identified. ► A risk assessment was made for each identified source. ► Applicable to other areas, the approach provides information for pollution control.
