Essay on Thermal Pollution for School Student in English
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 thermal pollution essay returned to the natural environment at a higher temperature, the change in temperature decreases oxygen supply, and affects ecosystem composition, thermal pollution essay. Urban runoff—stormwater discharged to surface waters from roads and parking lots—can also be a source of elevated water temperatures.
All plant and animal species that live in water are adapted to temperatures within a certain range. When water in an area warms more than they can tolerate, species that cannot move, such as rooted plants and shellfish, will die. Species that can move, thermal pollution essay, such as fish, will leave the area in search of cooler conditions, and they will die if they can not find them.
Typically, other species, often less desirable, will move into the area to fill the vacancy. Warm water. Warm water thermal pollution essay 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, amphibians and copepods. Thermal pollution may also increase the metabolic rate of aquatic animals, as enzyme activity, resulting in these organisms consuming more food in a shorter time than if their environment were not changed.
An increased metabolic rate may result thermal pollution essay food source shortages, causing a sharp decrease in a population. Changes in the environment may also result in a migration of organisms to another, more suitable environment, and to in-migration of fishes that normally only live in warmer waters elsewhere. This leads to competition for 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. Biodiversity can be decreased as a result. Elevated temperature typically decreases the level of dissolved oxygen in water. This can harm aquatic animals such as fish,amphibians and other aquatic organisms.
Thermal pollution may also increase the metabolic rate of aquatic animals, as enzymeactivity, resulting in these organisms consuming more food in a shorter time than if their environment were not changed. Thermal pollution essay increased metabolic rate may result in 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, food thermal pollution essay of the old and new environments may be compromised.
Some fish species will avoid stream segments or coastal areas adjacent to a thermal discharge. High temperature limits oxygen dispersion into deeper waters, contributing to anaerobic conditions. This can lead to increased bacterialevels when there is ample food supply, thermal pollution essay.
Many aquatic species will fail to reproduce at elevated temperatures. Primary producers are affected by warm water because higher water temperature increases plant growth rates, resulting in thermal pollution essay shorter lifespan and species overpopulation. This can cause an algae bloom which reduces oxygen levels. Temperature changes of even one to two degrees Celsius can cause significant changes in organism metabolism and other thermal pollution essay biology effects.
Thermal pollution essay adverse changes can include rendering cell walls less permeable to necessary osmosis, coagulation of cell proteins, and alteration of enzyme metabolism, thermal pollution essay. These cellular level effects can adversely affect mortality and reproduction. A large increase in temperature can lead to the denaturing of life-supporting enzymes by breaking down hydrogen- and disulphide bondswithin the quaternary structure of the enzymes.
Decreased enzyme activity in aquatic organisms can cause problems such as the inability to break down lipids, which leads to malnutrition.
In limited cases, warm water has little thermal pollution essay effect and may even lead to improved function of the receiving aquatic ecosystem. This phenomenon is seen especially in seasonal waters and is known as thermal enrichment.
An extreme case is thermal pollution essay from the aggregational habits of the manatee, which often uses power plant discharge sites during winter. Projections suggest that manatee populations would decline upon the removal of these discharges.
In general, thermal pollution essay waters are better habitat for plants and animals than warm ones because cold waters contain more dissolved oxygen. Many freshwater fish species that are valued for sport and food, especially trout and salmon, do poorly in warm water. Some organisms do thrive in warm water, often with undesirable effects. Algae and other plants grow more rapidly in warm water than in cold, but they also die more rapidly; the bacteria that decompose their dead tissue use up oxygen, thermal pollution essay, further reducing the amount available for animals.
The dead and decaying thermal pollution essay make the water look, thermal pollution essay, and smell unpleasant Releases of unnaturally cold water from reservoirs can dramatically change the fish and macroinvertebrate fauna of rivers, thermal pollution essay, and reduce river productivity.
In Australia, thermal pollution essay, thermal pollution essay many rivers have warmer temperature regimes, native fish species have been eliminated, and macroinvertebrate fauna have been drastically altered.
Due to the sudden fall of water temperature the contraction on dam and thermal pollution essay pylon may take place.
Cooling tower at Gustav Knepper Power Station, Dortmund, Germany Industrial wastewater. In the United States, thermal pollution from industrial sources is generated mostly by power plants, petroleum refineries, pulp and paper mills, chemical plants, steel mills and smelters.
Some facilities use once-through cooling OTC systems which do not reduce temperature as effectively as the above systems. For example, the Potrero Generating Station in San Francisco, which uses OTC, discharges water to San Francisco Bay approximately 10° C 20° F above the ambient bay temperature. During warm weather, urban runoff can have significant thermal impacts on small streams, as stormwater passes over hot parking lots, roads and sidewalks. Stormwater management facilities that absorb runoff or direct it into groundwater, such as bioretention 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 receiving stream. Noise pollution is excessive, displeasing human, animal, or machine-created environmental noise that disrupts the activity or balance of human or animal life. The word noise may be from the Latin word nauseas, which means disgust or discomfort, thermal pollution essay.
The source of most outdoor noise worldwide is mainly construction and transportation systems, including motor vehicle noise, aircraft noise, and rail noise. Poor urban planning may give rise to noise pollution, since side-by-side industrial and residential buildings can result in noise pollution in the residential area.
High noise levels can contribute to cardiovascular effects in humans, a rise in blood pressure, and an increase in stress and vasoconstriction, and an increased incidence of coronary artery disease, thermal pollution essay.
In thermal pollution essay, noise can increase the risk of death by altering predator or prey detection and avoidance, interfere with reproduction and navigation, and contribute to permanent hearing loss. There are many different types of noise pollution. There are man-made noises, such as those created by city traffic, construction sites, airports and subway terminals.
In fact, most forms of transportation have an associated noise factor. The other type of noise that can be disruptive and irritating are environmental, such as a loud thunderstorm or the noise created by barking dogs and other animals.
Your mind just turns the noise down to a livable degree. Many types of manmade products and equipment cause noise pollution, thermal pollution essay.
For example, household appliances, televisions, electronic cooling fans, vacuum cleaners, and HVAC equipment all contribute to thermal pollution essay noise pollution. Even your pets may create a certain level of noise. Noise pollution effects both health and behavior. Unwanted sound noise can damage physiological and psychological health. Noise pollution can cause annoyance and aggression, hypertension, thermal pollution essay, high stress levels, tinnitus, hearing loss, sleep disturbances, and other harmful effects, thermal pollution essay.
Furthermore, stress and hypertension are the leading causes to health problems. Chronic exposure to noise may cause noise-induced hearing loss. Older males exposed to significant occupational noise demonstratesignificantly reduced hearing sensitivity than their non-exposed peers, though differences in hearing sensitivity decrease with time and the two groups are indistinguishable by age A comparison of Maaban tribesmen, who were insignificantly exposed to transportation or industrial noise, to a typical U.
population showed that chronic exposure to moderately high levels of environmental noise contributes to hearing loss. High noise levels can contribute to cardiovascular effects and exposure to moderately high levels during a single eight hour period causes a statistical rise in blood pressure of five to ten points and an increase in stress and vasoconstriction leading to the increased blood pressure noted above as well as to increased incidence of coronary artery disease.
Noise pollution is also a cause of annoyance. Thermal pollution essay study by Spanish researchers found that in urban areas households are willing to pay approximately four Euros per decibel per year for noise reduction. The effects of noise pollution on human health is a complex topic since not only does it have a physical effect, but also a behavioral and even mental effect. Noise can make a person nervous, antsy, irritable and, in some cases, angry.
Some noises are cited as being responsible for aggressive behavior in some individuals. Noise can have a detrimental effect on animals, increasing the risk of death by changing the delicate balance in predator or prey detection and avoidance, and interfering the use of the sounds in communication especially in relation to reproduction and in navigation.
Thermal pollution essay overexposure can lead to temporary or permanent loss of hearing. An impact of noise on animal life is the reduction of usable habitat that noisy areas may cause, which in the case of endangered species may be part of the path to extinction. Noise pollution has caused the death of certain species of whales that beachedthemselves after being exposed to the loud sound of military sonar see also Marine mammals and sonar.
Noise also makes species communicate louder, which is called Lombard vocal response. These unheard voices might be warnings, finding of prey, or preparations of net-bubbling. European Robins living in urban environments are more likely to sing at night in places with high levels of noise pollution during the day, suggesting that they sing at night because it is quieter, and their message can propagate through the environment more clearly, thermal pollution essay.
The same study showed that daytime noise was a stronger predictor of nocturnal singing than night-time light pollution, to which the phenomenon is often attributed.
Zebra finches become less faithful to their partners when exposed to traffic noise. An important factor in applying these strategies is a computer model for roadway noise, that is capable of addressing local topography, meteorology, thermal pollution essay, traffic operations and hypothetical mitigation, thermal pollution essay.
Costs of building-in mitigation can be modest, provided these solutions are sought in the planning stage of a roadway project. Altering flight paths and time of day runway has benefitted residents near airports. You must thermal pollution essay logged in to post a comment. Contact Us.

Thermal pollution or thermal enrichment is the contamination of water quality due to the change in water temperature. A common and major cause of thermal pollution is the use of water as a coolant. Most of the factories use water to cool their heated machines. Further, they release the same water in its previous place Thermal Pollution Recently, as a result of the increased energy demand, we've allowed our planet to begin overheating. With the introduction of more and more heated water into our lakes and rivers, and Carbon Dioxide into the atmosphere we've managed to raise the temperature of this vast resource. Even more ignorant is our failure to learn from our mistakes
