TL;DRAbstract

Sediment samples were collected from various locations along the Ogun River basin after which they were subjected to physicochemical analysis in order to determine the concentration of metals in the sediments as well as other sediment characteristics like pH, texture, cation exchange capacity etc. The samples were collected using a Van Veen Sediment grab after which they were stored in labeled polythene bags and transported in ice packed coolers to the laboratory. They were air dried, sieved and hand pulverized. Sediment trace metal analysis was determined using the Inductively Coupled Plasma Optical Emission Spectrometry. Data obtained were subjected to Analysis of Variance (ANOVA). From the results obtained, Cd (1.00 ppm) from Lafenwa sediment exceeded the Environment Canada Sediment Quality Guideline (ECSQG) limit of 0.60 ppm. Pb values from Akin Olugbade (46.00 ppm), Lafenwa (323.00 ppm), Copper (46.00 ppm) from Lafenwa, sediment Hg values obtained ranging from 0.945-0.975 ppm were
