Abstract: The study of heavy metals contamination on surface water, and sediment in the Upper Bonny Estuary was investigated. Samples of surface water, and sediment were collected at 5 selected stations namely: Okochiri River (S1), Ekerekana Creek (POD, S2), Okari-Ama River (S3), Ogoloma Creek (S4) and Bonny Estuary (Control, S5). Physico-chemical parameters (pH, temperature, DO, conductivity, salinity, TDS, TOC, and THC) were analyzed according to standard procedures for surface water (APHA), while heavy metal parameters (As, Cd. , Cr, Pb, Hg, V and Zn) were analyzed for water, and sediment using Atomic Absorption Spectrophotometer. The results obtained indicated that the physico-chemical parameters varied significantly (P Pb> Ni > V> Cd. As and Hg were not detected in the study. The degree of contamination in sediment revealed that the Contamination Factor of the studied metals in both seasons were all
