ASSESSMENT OF THE DISTRIBUTION OF HEAVY METALS IN BONNY RIVER, NIGERIA

ABSTRACT The study investigated heavy metal levels in the Bonny River. Water and sediment samples, collected at four major sites selected along the river course, were analyzed for heavy metals (Pb, Zn, Ni, Cd, Cu, and As) using standard methods. The pH in water was higher (7.94) than in sediment and EPA standards (6.5-7.5) and in water; it was lower than the recommended values for EPA and WHO. Descriptive statistics and Pearson correlation were used to analyze data at PAs>Cu>Pb>Cr>Cd>Ni. ...
