Background: Polycyclic aromatic hydrocarbons (PAHs) mainly release to the air from incomplete combustion of fossil fuels like oil, coal, wood, etc. Because of their bioaccumulation, carcinogenicity, and mutagenicity effects, they are one of the major concerns of the scientific community. In this study, the concentrations of PAHs in the ambient air of high-traffic areas in Isfahan City, Iran, during summer and autumn seasons of the year 2016 were measured.Methods: Air sampling was conducted passively using solid phase microextraction (SPME) fibers. The SPME samplers were installed in 7 points of selected high-traffic areas for 24 hours. After sampling, PAHs adsorbed on the fibres were directly analysed using a gas chromatography/triple quadrupole-mass spectrometer (GC/TQ-MS) device without the need to extraction according to standard methods.Findings: The maximum ΣPAHs was related to Azadi Square with a concentration of 53.83 ± 4.06 ng/m3 in autumn, and the minimum concentration of ΣPAHs was measured at Vahid Bridge with an average of 21.82 ± 1.28 ng/m3 in summer. Acenaphthylene was the highest found aromatic over the other PAH concentration. The mean concentration of PAHs in autumn was more than summer.Conclusion: The results showed that exposures to these compounds via ambient air at all stations, especially in high-traffic areas were higher than those suggested by Occupational Safety and Health Administration (OSHA), National Institute for Occupational Safety and Health (NIOSH), and American Conference of Governmental Industrial Hygienists (AGCCIH). High levels of these compounds in different parts of the city can be attributed to the excessive vehicle traffic as well as the topography of the city. Therefore, traffic management and control of emissions from vehicles can be very effective in reducing PAHs emissions.
