Description 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)
