Atmospheric Loadings of Lead From Refined Petroleum Products Consumption in Southwestern Nigeria

Deleterious impact of lead from the use of motor fuels is of major concern. Lead levels of gasoline and diesel samples from States in Southwestern Nigeria were analysed by Atomic Absorption Spectrometer, according to the standard ASTM D3237-97 method. Lead concentrations ranged from 0.491–1.903 mg/L for gasoline and 2.301–10.97 mg/L for diesel. Estimated lead levels in gasoline were below the Department of Petroleum Resources (DPR) Nigeria limit of 3.37 mg/l. Percentage lead contributions from gasoline and diesel fuel consumption were minimal due to various fuel lead-level regulations that have been established over the years
