The study investigates the levels of heavy metals and sediment quality in the Niger River.
Assessed concentrations of heavy metals in sediments at two locations: Agenebode and Illushi
Analyzed contamination factor and Pollution Load Index
Evaluated geo-accumulation index and ecological risk indices
Concentrations of Cu, Fe, Mn, and Zn were higher at Agenebode than Illushi
Moderate contamination for Cd and Pb in Agenebode, and Mn in Illushi
Overall metal pollution was not detected with Pollution Load Index below 1
