Thermal Pollution Essay | Essay on Thermal Pollution for Kids
Thermal pollution is the degradation of water quality by any process that increases the ambient water temperature. A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers:. Storm water discharged to surface waters from roads and parking lots can also be a source of elevated water temperatures. The warmer temperature decreases the solubility of oxygen and increases the metabolism of fish. Tropical marine animals are generally unable to withstand a temperature increase of 2 to 30°C thermal pollution essay most sponges, mollusks and crustaceans are eliminated at temperatures above °C.
Elevated temperature typically decreases the level of dissolved oxygen DO in water. The decrease in levels of DO can harm aquatic animals such as fish and amphibians. Thermal pollution may also increase the metabolic rate of aquatic animals, thermal pollution essay, as enzyme activity, resulting in these organisms consuming more food in a shorter time than if their environment were not changed. In Australia, thermal pollution essay, where many rivers have warmer temperature regimes, native fish species have been eliminated, and macro invertebrate fauna have been drastically altered and impoverished. An increased metabolic rate may result to fewer resources; the more adapted organisms moving in may have an advantage over organisms that are not used to the warmer temperature.
As a result one has the problem of compromising food chains of the old and new environments. As a result Biodiversity can be decreased. Releases of unnaturally cold water from reservoirs can dramatically change the fish and macro invertebrate fauna of rivers, and reduce river productivity. Increase in toxicity: The rising temperature changes the thermal pollution essay and chemical properties of water. A °C rise in temperature doubles the toxic effect of potassium cyanide. Interference with reproduction: In fishes, several activities like nest building, spawning, hatching, migration and reproduction etc.
depend on some optimum temperature. For instance, the maximum temperature at which lake trout will spawn successfully is 8. Increased vulnerability to disease: Activities of several pathogenic microorganisms are accelerated by higher temperature. Hot water causes bacterial disease in salmon fish, thermal pollution essay. Invasion of destructive organisms: Thermal pollutants may permit the invasion of organisms that are tolerant to warm water and highly destructive. Many of the planktons, small fish and insect larvae that re sucked into the condenser along with the cooling water are killed by the thermal shock, increased pressure and water viscosity, thermal pollution essay. Thermal pollution can be controlled thermal pollution essay passing the heated water through a cooling pond or a cooling tower after it leaves the condenser.
One method is to construct a large shallow pond. Hot water is pumped into one end of pond and cooler water is removed from the other end. Another method is using a cooling tower. During warm weather, urban runoff can have significant thermal impacts on small streams, as storm water passes over hot parking lots, roads and sidewalks. Storm water management facilities that absorb runoff or direct it into groundwater, such thermal pollution essay bio-retention systems and infiltration basins, can reduce these thermal effects. Retention basins tend to be less effective at reducing temperature, as the water may be heated by the sun before being discharged to a thermal pollution essay stream, thermal pollution essay.
