In the present study, both gaseous and particulate (PM with dae less then 2.5 µm) phases of polycyclic aromatic hydrocarbons (PAHs) were measured in the ambient air of Hamadan city, Iran. For this reason, two low-volume samplers equipped with glass fiber filters were used for sampling of particulate phase (N = 3 and XAD-2 sorbent tubes were applied for sampling gaseous phase of PAHs (N = 3. The sampling was conducted during warm and cold seasons in 2019. The average of cold/warm season ratios for Σ16PAH and PM concentrations were 1.14
