Abstract

Pollution problems are encountered in Ennore estuary as it receives industrial effluents and domestic sewage mostly in untreated condition. These affect water quality and living organisms. It has been estimated that about 449,000 litres/day of industrial effluents carrying heavy metals are let out into this estuary by these industrial establishments. Based on the present investigation, it may be stated that the presence of some metallic elements, with their synergistic effects would have poisoned the water resulting in the mass mortality of fishes and prawns and dislocation of the most bottom fauna from their habitat in this estuary.
