Abstract

The Joint Group of Experts on the Scientific Aspects of Marine Pollution (GESAMP) defines marine pollution as "the introduction by man , directly or indirectly of substance or energy into the marine environment including estuaries which results in such deleterious effects as harm to living resources, hazards to human health, hindrance to marine activities including fishing, impairment of quality for use of seawater and reduction of amenities" (GESAMP, 1984). Thermal heat) is one of the seven major categories of environental pollutant . Thermal pollution is any change in natural water temperature that adversely affects the aquatic environ.ent ". Thermal power plants may contribute significantly towards economic growth but they may bring associated ills of environmental pollution. The largest Single industrial use of water is for cooling purposes (Cairns, 1956) and vast quantities of water heated in this way are discharged into natural bodies of water. The main sources of thermal effluents from thermal power stations are; cooling water, waste water from water treatment plants and condenser cleaners, waste water contaminated with petroleum products such as oil and grease, water from hydraulic ash disposal system and water collected inside the territory of the power stations (Sarin, 1988). Thermal pollution due to cooling water, waste water and fly ash slurry discharges are bound to have detrimental effects on the hydrography of the receiving waters .
