DETERMINATION OF SOME HEAVY METALS IN 0REOCHROMIS NILOTICUS, CLAR/AS GARIEPINUS AND SYNODONTIS SPP FROM THE COASTAL WATER OF ONDO STATE, NIGERIA

Abstract

Some heavy metals (Pb,Ni,Fe,Cu,Zn,Cd ,Co,Mn,and  Cr)  were  determined  in  Oreochromis  niloticus,  Clarias  gariepinus and Synodontis spp obtained from the coastal water of Ondo State. All metals examined and  detected  in all fish  samples. Iron, manganese and cadmium were found to be the most abundant metals in the fish samples with an average values of 35.8, 31.3, and 12.5 mg kg·1 respectively. Except for manganese, iron and cadmium , Syndrontis spp has the highest concentration for virtually  all the metals  under examination.
