N D DON XAVIER S BIJOY NANDAN P R JAYACHANDRAN K V NEETHU D MOHAN S R MARIGOUDAR
The accumulation trends of Cu, Zn, Pb and Ni and their effects on two native species,
$\bullet$ The tissue-specific bioaccumulation and metal selectivity index (MSI) of E. suratensis and V. cyprinoides revealed significantly higher accumulation of Cu and Zn compared to Pb and Ni throughout the study with higher rates during non-monsoonal periods.
$\bullet$ The histopathological studies in fish, E. suratensis from field conditions portrayed significant histopathological alterations such as hyperplasia, deformed secondary lamellae in gill tissues; melanomacrophage centres and necrotic lesions in liver.
$\bullet$ The estimation of human health risk assessment of heavy metals (Cu, Zn and Pb) of E. suratensis from Cochin estuary denoted a possible risk from consumption of fishes from the Cochin estuary.
