Thermal Pollution
THERMAL POLLUTION
It is one of the pollution that effects on living things and the environment badly. The definition of thermal pollution is the degradation of water quality by any process that changes ambient water temperature.
A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. When water used as a coolant is returned to the natural environment at a higher temperature, the change in temperature decreases oxygen supply, and affects ecosystem composition. Urban runoff–stormwater discharged to surface waters from roads and parking lots–can also be a source of elevated water temperatures.
When a power plant first opens or shuts down for repair or other causes, fish and other organisms adapted to particular temperature range can be killed by the abrupt change in water temperature known as "thermal shock."
* Effects of thermal pollution on the environment
There are several effects of thermal pollution * The dissolved oxygen content of water is decreased as the solubility of oxygen in water is decreased high temperature * High temperature becomes a barrier for oxygen penetration into deep coldwaters. * Toxicity of pesticides, detergents and chemicals in the effluents increases with increase in temperature. * The composition of flora and fauna changes because the species sensitive to increase temperature due to thermal shock will be replaced by temperature tolerant species. * Metabolic activities of aquatic organisms increase at high temperature andrequire more oxygen level falls under thermal pollution. * Discharge of heated water near the shores can disturb spawning and can evenkill young fishes. * Fish migrations are affected due to formation of various thermal zones * Sudden and peroiodic increase in temperature producing a thermal effect * Distribution of organisms among major and minor communities. * Changes to reproductive powers and increased
