Road Construction and Vehicular Activities as Indicators for Heavy Metal Pollution in Osogbo Metropolis, South West Nigeria

The levels of heavy metals in soil samples from selected major roads under construction, burrow sites (a place where was obtained for road filling) and two use have been investigated. Soil were collected digested using standard methods. digests analyzed Ni, Cr, Zn, Cd, Cu Pb Atomic Absorption Spectrophotometer. data subjected to descriptive statistics, non linear regression one way analysis variance (ANOVA). results showed that cadmium had the highest Contamination Factor (CF). Pollution Load Index construction higher than each Burrow siteand Trunk C comparison. Ecological Risk sampling less 40 which indicated that, on did not pose ecological risks environment. all 150 indicating they fell within low risk category. study established site contribute metal concentration contamination traced vehicular activities.
