This study was carried out to assess the effect of some heavy metal concentration (Cr, Fe, Ni and Pb) in roadside dust using atomic absorption spectrophotometer (AAS) in three study sites sites (Farin-Gada, Terminus Roundabout and British America Junction) .The dust samples were digested using Aqua regia. All the selected heavy metals were detected in the roadside dust samples. In British America Junction the concentration of the metals ranged from 5.30ppm to 364.19ppm with Cd recording the least value and while Fe recorded the highest value. In Terminus Roundabout, the concentration of the heavy metals ranged from 0.77ppm to 371.97ppm with Cd recording the least and Fe the highest value. In Farin-Gada, the metals concentration ranged from 5.51ppm to 375.14 Cd recording the least and the Fe the highest value. However the selected heavy metals exceeded the WHO standard for heavy metals in dust indicating that vehicular emissions also contributed to the high concentration of these heavy metals in the dust samples.
