Abstract

An investigation of the heavy metal contents in road dust is vital in assessing the potential environmental impacts of vehicular emissions on the soil. In this study, dust samples were collected from Jos metropolis and were analysed for heavy metals (Pb, Zn, Mn, Cu, Co, Cd and Fe) using Atomic absorption spectrophotometer (AAS). The average distribution of the heavy metals decreased in the following order: Fe>Mn>Zn>Cu>Pb>Co>Cd, Fe had the highest values in all sampled areas while Cd showed no pollution due to the metal in all the sampled areas.
