摘要

Assessment of Heavy metals levels in Water and Sediment from Lake Njoboliyo, Yola-south, Adamawa State, Nigeria was conducted for the period of five months (January-May, 2018). Data were collected in three different sites bi-weekly in triplicate. The concentrations of heavy metals in water ranges during the period of the research were Cadmium (0.0144mg/l to 0.0256mg/l), chromium (0.0133mg/l to 0.0222mg/l), Copper (0.0133mg/l to 0.0244mg/l), Iron (1.3411mg/l to 4.2600mg/l), Zinc (0.0114mg/l to 0.4956mg/l). There was significant difference (P0.05) for all the heavy metals between sites and Months. All the heavy metals observed in the water samples were higher than the WHO except Copper which was within WHO permissible limits, indicating that the pollution of Lake Njoboliyo is moderate. The concentration of heavy metals in sediment ranges during period of study were Cadmium ranged between 0.0267mg/kg and 0.0700mg/kg, Chromium ranged between 0.0144mg/kg and 0.0467mg/kg, Copper ranged between 0.0166mg/kg and 0.3533mg/kg, Iron ranged between 26.1167mg/kg and 28.8644mg/kg, Zinc ranged between 0.1333mg/kg and 0.3878mg/kg, There was significant difference (P0.05) for all the heavy metals between sites and Months. All the heavy metals recorded in the sediment were within the permissible limit recommended by WHO and FEPA except Cadmium, indicating that the pollution of Lake Njoboliyo is moderate.
