Abstract: Environmental problems associated with water pollution are great. Obviously, the problems are connected to the damages done to the aquatic environment as a result of anthropogenic activities. Anthropogenic activities could have serious detrimental effects in the aquatic environment. These could go a long way in affecting the suitability of water and aquatic organisms from such an environment for human use. Levels of Pb, Ni, Fe, Cu, Co and Cd were evaluated in fish (Brycinus nurse) in order to assess the bioaccumulation of the trace metals in the fish with the view to ascertain the suitability of the fish from Issiet River in Uruan, Nigeria, for human consumption, The levels of the trace metals were also evaluated in water and sediment. Dry and wet seasons’ samples were collected and digested according to standard methods and analysed using Unicam 939/935 atomic absorption spectrophotometer. Physicochemical properties were also quantified in water samples using standard procedures. The results revealed variable levels of the investigated parameters in the samples. Trace metals levels in fish ranged from 0.0031±0.00 mg/kg Cd to 0.298±0.01 mg/kg Fe for the two seasons. The trace metals levels in fish, water and sediment were below the permissible limits stipulated by WHO and USEPA. Bioaccumulation factor analysis of trace metals in fish revealed the range: 1.15 of Cd to 3.06 of Ni from water for the two seasons and 0.23 of Cd to 1.11 of Pb from sediment. In conclusion, the analysed fish, water and sediment contained variable levels of the investigated trace metals. Their levels in the fish were below the limits that could cause toxicity in human consuming the fish, at the time of the study. Periodic analyses of the investigated trace metals in the river are highly recommended for the purpose of documentation and monitory.
