Abstract :

Anthropogenic activities within both the catchments and feeder streams of the Barekese reservoir are possible sources of heavy metals pollution in the reservoir. Accumulation of heavy metals to toxic levels in the reservoir may be detrimental to human health. Hence, levels of Hg, As, Pb, Ni, Cr and Cd were determined in water and muscle tissues of highly consumed fish species from the Barekese reservoir using AAS. Indices for non-carcinogenic and carcinogenic risks were estimated for children and adult upon their utilization of the Reservoirâ??s resources. Children are at a relatively higher non-carcinogenic risk through the consumption of metals in Heterotis niloticus whiles the consumption of Cr from all examined fish species from the Reservoir could pose cancer risk health effects to humans. Results of the study revealed that children and adults have hazard index (HI) > 1, suggesting a significant level of non-carcinogenic effects. Also, oral exposure to As and Cr in water from the Reservoir could result in a significant cancer risk effect to humans. However, As showed a significant carcinogenic health risk through dermal exposure to both children and adults. The present study concludes that anthropogenic activities such as the artisanal mining along the Offin River and the excessive use of agro-chemicals within the catchments of the Barekese Reservoir are deteriorating the water quality of the Reservoir.
