Abstract
Heavy metal concentrations (Cu, Pb, Zn, Ni, Cd) in cassava roots cultivated on farmlands along the Ilaro-Ibese road were studied. Cassava root samples were collected from cassava farms in three different spots within the farmland. The concentration of these metals was determined using ICP-OES (Agilent 720-ES). Cu (5.1883 mg/kg), Ni (0.1552 mg/kg) Zn (0.1204 mg/kg), Pb (0.0581 mg/kg), and Cd (0.0432 mg/kg) had significant metal concentrations in cassava root. Heavy metal concentrations in cassava roots were in the following order: Cu > Ni > Zn > Pb > Cd. In comparison to other spots (i.e., 10 and 15 m distances), the concentration of heavy metals in cassava roots planted at 5 meters away from the major road is high. The bioaccumulation of heavy metals in cassava roots observed in this study is generally lower than the WHO/FAO acceptable limit (2001). For all metals, the soil plant transfer factor values at all sites indicated medium accumulation.
