HEAVY METALS OCCURRENCE IN THE TISSUES OF MARINE PRAWN Penaeus monodon (FABRICIUS 1798) AND WATER ALONG THE COASTLINE OF TAMIL NADU (CHENNAI)

This current study aimed to gauge the cluster of heavy metals, Copper, chromium, manganese, Cadmium, Lead, and zinc were determined in seawater, marine prawn's hepatopancreas and muscle tissue. The trials were collected from three diverse locations along the coastline of Tamil Nadu (Chennai); Kasimedu, Lighthouse, and Muttukadu. Atomic Absorption Spectrophotometer was performed for heavy metal analysis. The mean cluster of heavy metals in water at all trail places follows in descending order of Mg > Zn > Cd > Cu >Pb> Cr during the period July-September 2019. The spreading range of heavy metals in the prawn samples was as follows: hepatopancreas > muscle. The present analysis recorded that there were variances in heavy metal levels between diverse places. This indicates the ability of crustaceans to accumulate heavy metals to detectable levels. Metal bioaccumulation by shrimps can be affected by the chemical composition of the seawater. Variations in heavy metal clusters among diverse places are probable to have ensued from hydrodynamics, metal bioaccessibility of the environment, change in tissue composition, stations of collection and sources of pollution within the Bay of Bengal, Chennai coast.
