Effect of Crude Oil Pollution on Soil and Proximate Composition of Cassava from Owaza in Ukwa West Local Government Area of Abia State, Nigeria

This work investigated the level of Total Hydrocarbon Content (THC), trace metals, physicochemical properties of the soil sample of Owaza shell location farmland and the level of proximate composition of cassava tubers from the same farmland so that proper evaluation could be reached following standard procedures. The result of the physicochemical analysis revealed that the pH of the polluted soil sample were slightly acidic than the control and the bulk density increased above 1.6 g/cm3 that tend to restrict root growth. The THC and the trace metal level in both soil and cassava samples from the polluted farmland increased, which could be deleterious to living organism including man within affected communities. The proximate composition of the cassava sample from the polluted soil sample was also affected as the calorific value decreased (251.60
