Polycyclic aromatic hydrocarbons (PAHS) which are toxic pollutants are released by various sources of urban combustion. Ahvaz in Iran with around a million population and the industrial and oil centers, has encountered air quality problems. Samples of Dibenzo (a,h) antheracen were collected from six stations in Ahvaz particle and gas phase in summer 2010.

Dibenzo(a,h) antheracen were collected from (PAHs) using SKC pump on PTFE filter and Surbnt tube XAD2 with polyurethane separation foams.

The samples were analyzed by gas chromatography liquid (HPLC) equipped with Fluorescence detectors with the wavelength of (410 nm and emissions output of 290nm) based on 5506 NIOSH method. The mean of the concentration Dibenzo(a,h) antheracen with the maximum range of 8508/06 to the minimum range of 64/50 was provided in ng/m3 for Naderi station to residential steel homes.

Dibenzo (a,h) antheracen with five rings was reported more than 70% in particle phase and the main source of pollutants in the range of high traffic due to the use of fuel (gasoline) in vehicles and was more than the air quality standard in all of the stations.
