Thermal Pollution Essay - 818 Words

Thermal Pollution Recently weve allowed our planet to begin overheating. With the introduction of CFCs and Carbon Dioxide into the atmosphere weve managed to raise the temperature of this vast resource. Even more ignorant is our failure to learn from our mistakes. Now, through thermal pollution (the introducton of waste heat into water), weve began destroying the womb of all life-the earths vast water network. The Causes: There are three major causes of thermal pollution. the use of water as a cooling agent deforestation of shorelines soil erosion The foremost cause being the use of water as a cooling agent in nuclear power plants and other industrial facilities. After the water has absorbed the†¦show more content†¦The pile up of dead plants leads to an increase of bacteria, bacteria that consume oxygen along with dead plants. Therein lies the problem. There is now less oxygen and a greater demand for it. The warmer water also increases the metabolic rate of fish, which leads to a sharp decrease in the life expectancy of aquatic insects. The fish have an increasing the need for oxygen due to a rise in their metabolism and population. With the lack of aquatic insects animals other than fish face a shortage of food. Also affected by thermal pollution is an animals sensitivity to toxic waste, parasites, and other diseases. Water pollution Water pollution involves the release into lakes, streams, rivers, and oceans of substances that become dissolved or suspended in the water or deposited upon the bottom and accumulate to the extent that they interfere with the functioning of aquatic ecosystems. It may also include the release of energy in the form of radioactivity or heat, as in the case of thermal pollution. Any body of water has the capacity to absorb, break down, or recycle introduced materials. Under normal circumstances, inorganic substances are widely dispersed and have little or no effect on life within the bodies of water into which they are released; organic materials are broken down by bacteria or other organisms and converted into a form in which they are useful to aquatic life. But, if theShow MoreRelatedThe Development And Application Of Nanomaterials Has Allowed972 Words   |  4 Pageselectricity costs and energy used, the construction industry has begun to use aerogels because of their thermal insula tion properties. Aerogels are three-dimensional structures of nanoparticles with small pockets of space inside. These nanopores, or interstices, help in trapping air. About 99.8% of an aerogel is air (Soutter, 2012). Air is one of the best thermal insulators due to its low thermal conductivity. Thus, the use of aerogels as insulators is becoming increasingly common. Aerogel is saidRead MoreThe Effect Of Thermal Comfort On Human Comfort Essay1437 Words   |  6 Pagesaffecting human comfort (i) Thermal comfort (ii) Lighting comfort (iii) Acoustic comfort (i) Thermal comfort Thermal comfort is difficult to measure because it is highly subjective. It depends on the air temperature, humidity, radiant temperature, air velocity, metabolic rates, and clothing levels and each individual experiences these sensations a bit differently based on his or her physiology and state. The six basic factors The most regularly utilized marker of thermal comfort is air temperatureRead MoreSubjective Measurement Of Thermal Preference1903 Words   |  8 PagesNot comfortable 1 5.9 - - - - - - - - - - 2 11.8 - 2 11.8 3 17.7 4 23.5 1 5.9 Table 6: Subjective measurement of thermal preference MAY’13 JUN’13 JUL’13 AUG’13 SEPT’13 OCT’13 NOV’13 DEC’13 JAN’14 FEB’14 MAR’14 APR’14 N % N % N % N % N % N % N % N % N % N % N % N % Much warmer - - - - - - 15 88.2 - - - - 2 11.8 5 29.4 4 23.5 - - - - - - Warmer 15 88.2 14 82.3 15 88.2 1 5.9 13 76.5 14 82.3 8 47.1 8 47.1 7 41.2 - - 3 17.7 4 23.5 Slight Warmer 2 11.8 3 17.7 2 11.8 1 5.9 4 23.5 3 17.7 5 29.4 3Read MoreAssignment : Human Comfort Within Buildings Essay1079 Words   |  5 Pageswill feel refreshed all day.
