Abstract: Polycyclic aromatic hydrocarbons (PAHS) have been determined in the atmosphere of Isfahan, Iran. Airborne particulate matter was sampled using a high-volume air sampler at roof-top level (~6m). Extraction of PAHS from airborne particulate matter has been performed using SFE system and the relationship between the extraction temperature and the recovery of PAHS from airborne particulates is investigated. Determination of 16 PAHS has been carried out by GC-MS technique. Variation in concentration of PAHS has been compared to those for organic carbon and total suspended particles (TSP). A good agreement was found between the variation in concentration of PAHS and that for organic carbon, but weak correlation (p=0.6, r2=0.42) was found to exist between the PAHS and TSP
