Determination of the Sulfur Content of Gasoline from Four Major Fuel Distributors in Dakar

Sulfur dioxide is an acidifying gaseous pollutant. It contributes to the acidification of the environment. When emitted into the air and in the presence of water, sulfur dioxide forms sulfuric acid, which contributes to the phenomenon of acid rain. Acidifying substances disrupt the composition of air, surface water and soil. Sulphur dioxide (SOx) emissions are closely linked to the use of fuels containing sulphur, and the maximum permitted sulphur content is one of the most closely monitored fuel parameters. In this article, we determined the sulfur content of gasoline samples taken from four service stations belonging to the most representative groups in terms of light petroleum product distribution in Senegal. The aim is to assess the environmental impact of sulfur dioxide emissions resulting from the use of gasoline by vehicles, and to reduce upstream sulfur content.
