INDUSTRIAL IMPACT ON SELECTED HEAVY METALS IN ECONOMIC FISH WITHIN THE RIVER IN NNEWI-NORTH LOCAL GOVERNMENT AREA, ANAMBRA STATE NIGERIA

This work was carried out to research on the Industrial impact of selected heavy metals in economic fish samples Eze river Nnewi-North, Anambra State, Nigeria. The levels seven (Pb, Mn, Zn, Ni, Cr, Cu, and Cd) (Clariasgariepinus, Oreochromisneloticus, Pseudotolithus elongates) from area were detected using Flame Atomic Absorption Spectrophotometric technique. HN03-HCl method used sample digestion. All collected contained six analyzed. mean concentrations(µg/g) studied 1.85 for Pb, 0.86 3.38 1.18 2.84 Cu 0.43 Cd. With exception Pb Cd most within acceptable fish. target hazard quotient (THQ) index (HI) values evaluated order assess health risk inhabitants Nnewi-north environs due metal intake food crops. less than 1 all samples; therefore, their consumption does not pose any concern. Metal-metal correlation Pearson’s product moments. Most elemental pairs show significant with each other, this implies that paired element has common pollution sources. In conclusion, investigated been affected by industrial activities. So control measures stated regulatory authorities should be enforced industries.
