Abstract
This study was conducted during season of March to May to determine the metal pollution in water and Bioaccumulation into freshwater fishes of Catla catla, Labeo rohita, Notopterus notopterus and Cirrhinus mrigala were collected from the two different places within the river Son. The gill and muscle tissues of fish were analyzed for Cd, Cr, Cu, Pb, Ni and Zn using Atomic Absorption Spectrophotometer (AAS- Model AA500 PG Instruments, UK). The levels of heavy metals in the freshwater were found to be higher than the WHO recommendations. The fish samples were also high levels of heavy metals than the WHO [23] recommendations. The fish tissues of gills were observed highest level of heavy metals than the muscle tissue. The metals were accumulated in descending order as follow: Zn>Cu>Pb>Ni>Cr>Cd. The present study shows that the high-level bioaccumulation of metal in fish and water that could be unsafe for human consumption.
