Abstract
This study evaluates heavy metal accumulation in cassava (Manihot esculenta) grown on the soils irrigated with textile effluent. Root samples were collected from effluent-affected and control fields. Samples were digested and analyzed via AAS/ICP-OES to quantify lead (Pb), cadmium (Cd),chromium (Cr), zinc (Zn) and copper (Cu). The results revealed that effluent-irrigated sites accumulated significantly higher concentrations of lead (Pb,9.1μg/kg) compared to the control. Cadmium (Cd) levels were extremely elevated (29.4 μg/kg), exceeding those of the control by more than tenfold. Chromium (Cr) concentrations were slightly higher (66.9 μg/kg), while zinc (Zn, 50.3 μg/kg) and copper (Cu, 21.4 μg/kg) showed moderate increases relative to the control.
