This study employed turbidimetric method using a UV/VIS spectrophotometer to determine the totaludsulfur levels of refined petroleum products in Southwestern Nigeria. The sulfur concentrations in the analyzedudfuel samples were 0.0019–0.0178 wt% and 0.027–0.169 wt% for gasoline and diesel, respectively. Sulfur levels in the selected samples were below the Nigerian standard for gasoline and diesel while 89.9% of the samples exceeded the U.S. Environmental Protection Agency standard. The turbidimetricudmethod showed better performance than the gravimetric method. The results gave insight into the adverse environmental impact the nonuniform quality of fuels imported could pose to the country.
