Heavy metal toxicity is a serious threat to human health due its bioaccumulation, biomagnification, and persistent nature in the environment including aquatic systems. In recent past, heavy contamination has occurred various anthropogenic sources. The concentration of potentially toxic metals was determined by Atomic Absorption Spectroscopy Tilapia ( Oreochromis mossambicus ), highly farmed consumed fish species southern parts India. mean levels Fe were found be higher major organs with highest liver (Mean 1554.4 ± 1708.7 mg/kg) lowest muscles 130.757 33.3 mg/kg). Correlation Matrix analysis revealed relationships between occurrence different indicated similar origins chemical properties. Target hazard quotient for Cd, Co, Pb, Cr Liver, Co Gills, Muscle &gt; 1 adults, which showed significant risk from combined effects these metals. potential humans, according cancer (CR) assessment attributed mainly Cd levels. Overall, moderate consumption advised limit bioaccumulation over prolonged exposure associated risks.
