Study on Accumulation of Heavy Metal Concentrations in the Tissues of Aquatic Species from Ennore Estuary

Rapid industrialization along with advanced agricultural activities led to the contamination of aquatic environment with heavy metals. Heavy metals ultimately pass into human body through aquatic animals. The aim of the present study was to determine the concentrations of heavy metals such as cadmium (Cd), mercury (Hg) arsenic (As) chromium (Cr) and lead (Pb), in the tissues of fish, shrimp, crab, mussel and lobster from the Ennore estuary. The result shows that all the tested animals were highly exposed to heavy metal concentration in the Ennore estuary. Higher metal contamination in Ennore estuary is posing considerable ecological risk as per environmental quality indices, exposing to heavy metals at higher concentrations might be toxic to fish species as well as humans.
