Volatile organic compounds (VOCs) are one of the most prominent air pollutants that are of particular importance due to their serious toxicants as carcinogens. Due to the harmful effects of VOC compounds on human health, adverse effects on plant degradation and global climate change, it is necessary to prevent their release into the air. The most important sources of VOCs in urban areas are traffic and transportation, gasoline vapors, solvent use and etc. The emissions of VOC from gas stations can be considered seriously. According to research, one of the major sources of VOC pollutants in cities is gas-fueling stations. These studies have been evaluated by many researchers around the world and the volatile organic compounds content is often above the reported international standards (Gonzalez et al, 2002; Kountouriotis et al, 2014, Hicklin et al, 2018).<br />In 2006, three different gas stations were measured, with results ranging from 512 to 1275 μg/m³ in New Delhi (Srivastav et al, 2006). In 2015, a study was carried out at six gas stations in Tehran that showed average concentrations in summer at 860 ppm and in winter at 434 ppm (Eisaei et al, 2015). In another study by Hicklin et al., Volatile organic compounds were distributed in gas stations using two models in Malta, which showed most gas stations were built in residential areas that exceed the standard level (Hicklin et al, 2018).
