Vehicular emission has been found to constitute one of the major sources of soil pollution. We have investigated the influence of vehicular emissions on the accumulation of heavy metal in the roadside soils of Ota metropolis, Ogun State, Nigeria. The main objective of this research was to determine the impact of heavy metals such as copper, cadmium, lead, manganese, nickel and sulphate from vehicular pollution on soil around Ota. Seven locations were selected on the basis of their high concentration of vehicular traffic. Three sites with low traffic concentration were also selected outside the seven locations to act as control sites. Samples were taken in a period of three months in the dry season. The concentrations of five heavy metals and sulphate in the samples were determined with an atomic absorption spectrometer. The concentrations of the heavy metals from the seven main sites were higher than in the control sites. The concentration of each heavy metal and sulphate in the seven locations was below the European Union regulatory standard. Although these concentration are below the European Union regulatory standard, these heavy metals and sulphate, which over time are washed by erosion into the local areas used for farming, may pose health hazards. The enhancement of fuel quality and the adoption of emission standards to mitigate the impact of vehicular emissions on human health should be made mandatory.
