Effects of Thermal Pollution

Pollution can be defined as an undesirable  change in the physical ,chemical or biological characters of land ,air or water that may or will  effect harmfully the human life, its properties ,aesthetics, health and all other such perspectives of  civilization. 

DEFINITION OF THERMAL POLLUTION:

 In a very general way , thermal pollution can be defined as the phenomenon by which the normal temperaturter of  ambient  sources of water  face an increase in temperature.It can be contributerd tothe high temperature  discharges from industries , power stations etcetra ,into the adjoining water body whereby the heated or warm water increases thewater  temperature  

EFFECTS OF THERMAL POLLUTION  IN WATER:

Other than man made  sources of  aquatic thermal pollution, changes in vegetation cover along the banks of the water body  or increase in turbidity has been reported to cause increasing in temperature.                                       

Sources of thermal pollution:       

* Removal of trees along the shore line  increases solar incidence and  hence    warms up  the water along with deforestation

* Power plants  --goth nuclear and coal  use thousands of gallons  of water for their  reactor  but return water is much hotter.

* Dumping  of waste warm water by    nuclear plants.

Effects of Thermal Pollution

There are several effects of tthermal pollution

* Sudden and peroiodic increase in  temperature producing a thermal  effect

* Changed dissolved oxygen

* distribution of organisms among major and minor communities.

* Death of steno hermic animals

* Changes to reproductive powers and increased susceptibility to disease

* production of heat shock proteins for thermotolerance.

* changes in migration time and pattern may be affected.

* Bio indicators are the first to show the effects

* Decrease in productivity of the...
