Heavy metal pollution is a very serious issue in the present world and is caused by release of toxic substances from industrial and domestic sources into the sea water leading to harm marine organisms. Marine fishes are commonly consumed for its nutritional benefits' and thus lead to transfer toxic metals into the food chain. Harpodon nehereus is a common and local fish from west coast of Maharashtra with high consumption rate among local population. Fish organs particularly liver being major site of detoxification shows structural alterations on exposure to pollution stress from their surrounding environment. Histopathological examination provides an indication of organ impairment to evaluate the health status of selected fish and the degree of pollution in marine environment. The present research effort was done to evaluate the concentration of heavy metals and to study histopathological alterations in liver tissues of largely consumed fish Harpodon nehereus collected from Sassoon dock, west Coast of Maharashtra, India. The research was carried out during the post-monsoon season of the year. High accumulation of lead 11.8 Ã‚Â± 8.34 mg kg , copper 20.46 Ã‚Â± 11.06 mg kg and Zinc 286.26 Ã‚Â± 114.5 mg kg were observed in liver tissues. Further histopathological study of present investigation reveals heavy damages in liver tissues of Harpodon nehereus representing that the selected fish is under high threat of pollution stress.
