Introduction: Street dust mainly is influenceed by pollution Polycylic aromatic hydrocarbons (PAH). PAHs are organic compounds which are formed from carbon and hydrogen and two or more benzene rings. Presence of these compounds in the dust of the street, from various sources in the city, like traffic and industry and may also affect human health and the environment. The aim of this study was to evaluate the effect of compounds on human health and the environment.

Materials & methods: In order to assess and determine the possible origin of polycyclic aromatic hydrocarbons (PAHs) in the street dust of Ahvaz city, 10 samples of dust were collected from the city in March 2014. After preparation, the samples were analyzed by GC / MS. To determine the possible source of polycyclic aromatic hydrocarbons, geochemical aromatic ratios, statistical analysis, cluster analysis (CA), and principal components analysis (PCA) were used.

Findings: From 16 PAHs determined by the EPA, 13 PAHs were detected in dust samples. The total concentrations of PAHs were detected between 271.56 to 3211.58 Ppb. The ΣCOMB / ΣPAH was between 0.53 to 0.71 Ppb with 0.66 Ppb average. Ant / (Ant + Phe) was between 0.10 to 0.37 Ppb and BaA / (BaA + Chr) between 0.17 and 0.57 Ppb and IND / (IND + BGP) between 0.28and 0.37Ppb respectively. Probable carcinogenic were calculated by the toxicity equivalent factor (TEF) for PAHs in all sampling stations, it was lower than value of which is determined by Canada to protect human health (600BaPeq Ppb).

Discussion & Conclusions: The results indicate pyrogenic source for PAH of street dust and combustion of fossil fuels. B (a) P is most cancer PAH compound, were detected in all sampling stations with different concentrations. Also, the result indicate that Ahvaz city is intensively affected by the oil and gas upstream and down industries and PAHs can correlate with this industries.
