Abstract
There has been a rapid turnaround from meat consumption to fish consumption in Nigeria over the last few years. As at 2013 the rate of fish consumption in Nigeria has risen to 2.6 million tonnes with a per capita consumption of 13.5 kg. Heavy metals bio-accumulate in fishes especially when the water body is polluted. Hence humans are at risk of being affected by these metals via the consumption of contaminated fish fish products and other aquatic foods captured from a contaminated river for this reason there is need to monitor the level of heavy metal concentration in water bodies where they are caught. Analyses were done on fourteen (14) elements (Fe Ni Cr Cu Mn As Zn Ca Ti Se Rb K Sr Co) in three different fish species were analysed using Energy Dispersive X-ray florescence (EDXRF). The result showed that the mean values of Cr Mn Fe Ni Cu Zn and As were all Higher than the recommended FAO/WHO standards. Generally metal concentration in the gills is higher than that of the muscles for each species except Zn Se and Fe in which is higher in the muscle for Tilapia fish and Fe K and Rb which is higher in the muscle for Catfish. The target hazard quotient (THQ) of each metal through consumption of fishes from Oluwa river for both adults and children increased in the following order: Fe Ni Cr Cu Mn As.
