Abstract:

The Uppanar estuary runs behind the SIPCOT complex which is located at Cuddalore. A s the estuary receives the treated and partially treated effluents from nearly 55 industries and it is said to be highly polluted. The present study was carried out to find the accumulation of heavy metal, mercury in water, sediment and some tissues of shrimp, Penaeus monodon. The accumulation of heavy metal, mercury in water and sediment increased every month and it was higher at station-II which was located nearer to the industrial belt area. The accumulation of heavy metal, mercury in the gills, hepatopancreas, testis and vas deferens also increased every month and it was found to be higher at station-II. Among the various organs, bioaccumulation was higher in hepatopancreas and lower in gills. The higher accumulation of the heavy metal, mercury in the hepatopancreas may be due to uptake of nutrients and it is the storage organ of inorganic reserves. Large amount of accumulation of heavy metal in the tissues of shrimp in the industrially polluted area clearly revealed the effect of heavy metal, mercury which impacts the inhabitants, especially shrimps, in the Uppanar estuary. The accumulation of the heavy metals in the shrimps will reach the human beings and will result in ‘biomagnifications’. This hazardous situation may be prevented by treating the effluents properly before being let off into the Uppanar estuary.
