The study aims to explore the factors influence on the VOC emissions for two service stations located in Nantou County. Additionally, pollution control strategies for service stations will be proposed in the study. The methodology used to determine the controlling factors is by performing correlation analysis and analysis of variance (ANOVA). Results from 24-hour monitoring show the VOC concentrations in the daytime hours are significantly higher than during the nighttime hours. Furthermore, ambient VOC concentrations are elevated as increasing the volume of gasoline dispensed, and the gasoline dispensed has a diurnal pattern. Correlation analysis indicates the strength of correlation is in the order of exit > entrance > building in Sunlong service station. The order for correlation coefficient is exit > building > entrance in Chengkuan service station. According the ANOVA analysis, the total VOC concentrations are different from the individual average VOC concentrations measured from “the entrance”, “exit”, and “building” monitoring sites for both two service stations. To reduce the VOC emissions, it is recommended to increase the installation percentage for gas refueling gun, especially, in the area of dense loading of service station such as Tsaotun town and Mingchien town.
