Abstract
The advancement of industrialization and urbanization along the coastal region has received considerable attention of environmental scientists in the recent past. Owing to an increasing trend in the above factors, large volume of untreated industrial, agricultural, domestic and other wastes are frequently discharged into the sea. This indiscriminate discharge of the waste materials may endanger the safety of the aquatic life and even may cause irrepairable damage to the otherwise very delicately balanced marine ecosystem. Besides, some industrial waste water may contain high concentration of toxicants at lethal or near lethal level. If such untreated waste water is discharged into the sea, the toxicants may be picked up by fishes and shell fishes and these get concentrated in the tissues until the organisms are no longer fit for human consumption (Hammond, 1971). The ever increasing demand of electricity for industrial and domestic purposes has urged the Government, Public and Private sectors to install more and more electricity generating stations. The location of any industry is selected based on both the availability of reasonably good water for the industrial processes and the facility for discharging the wastes. The thermal power plants are always installed near to larger water bodies such as reservoir,lakes and sea and these plants use an enormous amount of water as transfer medium to remove the heat from the condensers and dissipate it into the nearest aquatic environment. The pumping rate of cooling water varies widely according to the design of the plant. Pannel et al (1962) have pointed out that dispersion of heat will be by mixing with water and not by cooling to the atmosphere. As a result of this, the effects of heated effluent are felt at a greater distance from the out fall than if the heated water was spread out and cooled at the surface (Raymont and Carrie, 1964; Ansell, 1963b)
