Abstract

Samples of Blackchin Tilapia (Oreochromis niloticus) from Anyia-Ogologo River, Mgbuosimini Community were collected, preserved and analyzed. The sampling covers a period of one year (wet and dry seasons). Atomic Absorption Spectrophotometric technique for heavy metals and Health Risk Assessment showed that the high levels of heavy metals Ni, Pb, Cd, and Co pose probable high toxic and carcinogenic risks in adults and children.
