Meteorological dependence, source identification, and carcinogenic risk assessment of PM_2.5-bound Polycyclic Aromatic Hydrocarbons (PAHs) in high-traffic roadside, urban background, and remote suburban area.

ABSTRACT: The Polycyclic Aromatic Hydrocarbons (PAHs) bound to ambient fine Particular Matter (PM_2.5) are currently drawing a lot of attention due to their adverse health effects increasing lung cancer risk in humans. In this study, The PM_2.5 samples were collected by high volume air samplers simultaneously from three different sites (high-traffic roadside, urban background, and remote suburban) in Tehran, Iran during warm and cold seasons (from July 2018 to March 2019), and 16 PAHs were analyzed using Gas Chromatography-Mass Spectrometry (GC-MS). Unlike previous studies, a remote suburban area was chosen so as to observe the spatial differentiation in PM_2.5-bound PAH characteristics. In high-traffic roadside site, the average concentration of total PM_2.5-
