Summary:Fishes are important for the maintenance and growth of living things, particularly human beings. Due to the nutritional value of fish, people are encouraged to include it into their diet. Fish is consumed in almost every house in Igbokoda, Nigeria and in the surrounding communities and is typically consumed in either (smoked, fried, cooked) condition. When these fish are polluted with heavy metals, they bioaccumulate and cause certain human organs to malfunction. The content of toxic elements in two different species (Mormyrus rume and Heterobranchus longifilis) of fish captured from the Igbokoda River of Ilaje was analyzed using Energy Dispersive X-ray Fluorescence (EDXRF). The result obtained showed that the mean values of all the elements were higher than the recommended FAO/WHO and International Atomic Energy Agency (IAEA) 407 standards, except for K, Ca, Sr and As, which were lower than the IAEA 407. Generally, the concentration of elements in muscle and head was higher than that of tail for each species for both M. rume and H. longifilis. The target hazard quotient (THQ) of each element through the consumption of Igbokoda fish for both adults and children increases in this order Mn > Cu > Ni > Zn > Fe > As > Pb and Mn > Cu > Ni > Zn > Fe > As > Pb for M. rume and H. longifilis respectively. •Metal concentration in the muscle and head were higher than that of the Tail for each species.•The (THQ) of each element through consumption of fishes from for both adult and children where high•The highest elemental concentration was Fe and the least concentration was Pb in both species
