ABSTRACT
The fresh water segment of the Qua Iboe River System is perturbed by both within the system and Drainage Basin Perturbation. The Drainage Basin pertubation includes farming, deforestation, heavy vehicular traffic, domestic effluents, gully erosion, urban runoffs, bank clear cutting and grazing by cattle. Using standard analytical method, the absorption rate of metals analyzed revealed non – alarming status and they followed the sequence Fe (0.8) > Ni (0.23) > Co (0.02) > Zn (0.01) > Cd (0.001±0.001) >Pb (Nil). The concentration of metals in the sediment were higher than those obtained for water and Pb was completely absent in both sediment and water samples. Proper administrative and legislative measures should be applied to protect the River System from possible increased pollution.
