Title: Assessment of metal bioaccumulation in Clarias batrachus and exposure evaluation in human
Abstract: The present work was conducted for heavy metal (Cr, Mn, Fe, Co, Ni, Cu, Zn, Cd and Pb) quantification in the river Ganga water and their bioaccumulation in vital organ tissues of Clarius batrachus. Heavy metal characterization in vital organ tissues (gills, liver and muscle) and comparison with FAO permissible guidelines revealed that Cd and Pb were hyper-accumulated which may lead to metal toxicity in fish and its consumers. High metal pollution index (MPI) was recorded for organ tissues of exposed samples (liver 6.05; gills 22.95; muscle 44.48) as compared to unexposed samples (liver 4.5; gills 18.8; muscle 36.76). Effective ingestive dose (EID) was calculated to assess the exposure threat to the human which may occur through dietary inputs. Results revealed that EID for Cr, Co, Cd and Pb was found significantly higher than the dose concentration prescribed by USEPA.
