Abstract
Heavy metal concentration in yam and cassava tubers from Enyigba Lead-Zinc mining site in South Eastern Nigeria has been studied. Results obtained were compared with those from control site where there is no mining activity. This study analysed the presence of Zn, Pb, Fe, Mn, Cu, As, Cd, Cr and Ni on cassava and yam tubers from contaminated soil caused by Lead-Zinc miningusing Atomic Absorption Spectrometer (Buck Scientific 210 VGP model).The metal concentrations in both yam and cassava samples are all above the WHO permissible limits from both affected locations except Chromium metal which falls within the WHO permissible/consumable limit.The variations of the level of heavy metals in cassava and yam tubers were analysed using the analysis of variance (ANOVA) in excel, at 0.05 significance levels (p<0.05).
