Thermal Pollution is an offshoot of rapid urbanization and unplanned industrialization with a heavy demand on thermal power palnts. Thermal Pollution may be defined as the warming up of the aquatic system to a point where the activities of aquatic plants and animals are adversely effected because of the discharge of heated effluents from the thermal power plants. Normally the aquatic life is well adjusted to dirurnal of heated effluents from the thermal power plants. Normally the aquatic life is well adjusted to diurnal and seasonal changes in temperature which occur naturally. However, due to man-made activities, rise in temperature of the water body brings about adverse changes in the ecological sufficient to damage the productivity and sustaining of aquatic life. Thus, when the heated effluents are discharged at a temperature 8 degree – 10 degree Celsius higher than the temperature of receiving water, significant changes are brought about in the aquatic system which disturb and damage the aquatic system.
SOURCES OF THERMAL POLLUTION
EFFECTS OF THERMAL POLLUTION
Heated waters, because of less density rise to the top and float over the water surface causing stratification. The insulates the lower layers of water from the atmosphere above with the result, the exchange of gases from water surface stops. Species intolerant to higher temperatures migrate to lower layers which are relatively cooler and denser. All this cumulatively results in creating oxygen deficit in both upper and lower layers.
