Background: The emission of gasoline vapour during the distribution, loading, evacuation, and transportation of petroleum products is a major cause of air pollution. Due to the closeness of the grain depot to the Fardis oil terminal. This study aimed to investigate the effect of pollutants emitted from the oil terminal on the level of BTEX compound contamination between the two storage sites. Materials and Methods: This cross-sectional-analytical study was conducted in 1400-1401. Monoaromatics were measured using a Focheck device made in Britain. The pollutants studied was benzene, toluene, xylene, and ethylbenzene. Data was collected for 125 samples over a period of one month. Measurements were taken between 9 - 10 a.m. Results: The oil depot's internal and external environments were measured, and there was a significant difference found (P<0.05). Significantly higher concentrations were reported for the pollutants studied in the external environment of the oil depot. After comparing the external environment of the oil depot, it was observed that the level of benzene was 0.46 mg/m3, which is roughly 0.09 above the environmental standard limit. After benzene, xylene, toluene, and ethylbenzene were in lower concentration levels, respectively. Conclusion: According to the study, the concentration of aromatic hydrocarbons outside the oil depot was significantly higher than those inside. Hence, the grain depot was more affected by the presence of vehicles than the oil depot, as can be inferred.
