Nellore has a coastline that stretches about 169 kms. Urbanization and coastal development activities such as beach
development, Krishnapatnam port expansions, industrial developments and anthropogenic metals are introduced into adjacent
waters of Nellore coast. In the study, estimated the bio-accumulation of heavy metal levels (Mercury (Hg), Lead (Pb), Cadmium
(Cd), and Zinc (Zn)) by Atomic Absorption Spectrophotometer (AAS) (AOAC-2000) in muscle and liver tissues of Cybium
guttatam (Seer) and Pampusargenteus (Silver pomfret) fishes which were collected from Krishnapatnam and Mypadu regions of
Nellore District. Study results showed that the metals content was determined in the edible parts of the selected fishes and the
obtained values were compared with maximum permissible limits set by International safety agencies. Selected heavy metals
(Hg, Pb, Cd and Zn) concentration in the muscle and liver of selected fishes varied significantly depending upon the locations.
