    were investigated. The TPH was determined by Fourier transformed infrared spectrophotomer, while heavy metals were analyzed with atomic absorption spectrophotometer. The values of TPH in soil impacted with petroleum activities was 5251.99 mg kg-1 compared to below detection level in non-petroleum impacted soil. All heavy metals showed higher values in petroleum impacted soil than non-impacted soil. The order of abundance of heavy metals in petroleum impacted soil was Fe > Mn > Zn > Cu > Co > V > Pb > Cr while in non-impacted soil, it was Fe > Zn > Mn > Cu > Co. The values of heavy metals were higher both in epicarp and mesocarp of plantain fruits harvested from petroleum impacted soil than from non-petroleum impacted soil. In cassava tubers, the values of heavy metals in the cortex were all higher in the petroleum impacted soil than non-impacted soil. Cr, V, As and Hg were all below detection levels both in plantain fruits and cassava tubers from both soils. The values of Zn (3.39), Pb (2.44) in the epicarp of plantain fruits and Zn (4.385) in the cortex and (5.955) in the piliferous layer and Pb (1.75) in the cortex of cassava were higher than the values recorded in soils indicating hyperaccumulation.
