Background:A critical environmental impact of the petroleum industry is the contamination of soil by oil and other related products which are highly toxic and exhibit molecular recalcitrance. Therefore, this study focused on investigating the total amount of petroleum hydrocarbons (TPHs) in soil of urban fuel stations in Hamedan City, Iran. Methods:Thirteen high traffic urban fuel stations were selected and random soil samples were collected from surface soils at selected fuel stations. The physical and chemical proper-ties of the soil samples were determined in the laboratory. The concentration of TPHs in soils was determined by GC/MC. Results: Results showed that concentration of TPHs in all stations was more than the stand-ard level in soil (2000 mg kg-1). The minimum and maximum TPHs concentration observed in No. 5 and No.13 fuel station, respectively. Conclusion: The results showed that spillage in urban fuel stations has clear effect on the content of TPH in soil, as concentration TPH in all of fuel stations was in the upper limit of the standard levels in soil. .Soil pollution with petroleum hydrocarbons has clear effects on soil biological, chemical and physical characteristics and results in decreasedg food elements, productivity and soil plant productions.
