The ozone layer protects us from the harmful rays of the sun; therefore it is imperative that we preserve it. Since more pollutants are produced today than ever before because of the major increase in the populationthere is a major concern that we create less pollutants to help conserve the ozone layer.
In this research paper I will give vital information on how pollution affects the ozone layer and methods instituted to help the ozone layer.
In this research paper you will also find out what the ozone layer actually is and the parts that it is composed of. All human activities take place in the troposphere. The next layer, the stratosphere, continues from 10 to 50 kilometers.
Most commercial airline traffic occurs in the power part of the stratosphere. Ozone is a molecule containing three oxygen atoms. It is blue in color and has a strong odor.
Normal oxygen, which we breathe has two oxygen atoms and is odorless.
Ozone is much less common than normal oxygen. Most importantly, it absorbs the portion of ultraviolet light called UVB. UVB has been linked to many harmful effects including various types of skin cancer, cataracts, and harm to some crops, certain materials, and some forms of marine life. At any given time, ozone molecules are constantly formed and destroyed in the stratosphere.
The total amount, however, remains relatively stable. While ozone concentrations vary naturally with sunspots, the seasons, and latitude, these process are well understood and predictable. Records have been established spanning several decades that detail normal ozone levels during these natural cycles.
Each natural reduction in ozone levels is followed by a recovery. Recently, however, convincing scientific evidence has shown that the ozone layer shield is being depleted well beyond changes due to natural processes.
Thinning of the ozone layer has been caused by a variety of ozone destroying chemicals released by human activities. More than half the damage has been caused by chlorofluorocarbons. They are stable, nonflammable, low in toxicity, and inexpensive to produce.
Over time, CFCs found uses as refrigerants, solvents, foam blowing agents, and in smaller applications.
CFCs and other compounds have atmospheric life times long enough to allow them to be transported by winds into the stratosphere. Because they release chlorine and bromine when they breakdown, they damage the protective ozone layer. Potential impacts of other chlorine sources were examined also.
Chlorine from pools, for example, do not reach the stratosphere. Those chlorine compounds readily combine with water and repeated measurements show that they rain out of the troposphere very quickly.
In contrast, CFCs are so stable that they do not dissolve in rain. There are no natural processes that will remove the CFCs from the lower atmosphere.
Over time, the CFCs are driven into the stratosphere by winds. It typically takes seven to ten years for CFC molecules to rise through the lower atmosphere and reach the stratosphere. When that happens, the CFC molecule releases atomic chlorine. One chlorine molecule can destroy overozone molecules.
Some two billion pounds of CFCs are manufactured every year. Gaseous emissions of CFCs, both during manufacturing processes and later, from finished products have caused atmospheric levels of chlorine to dramatically increase. Scientists estimate that before chlorine comprised 0.
Today, the chlorine level is about 3. The net effect is to destroy ozone faster than it is naturally created. Scientists are finding that under this assault the protective ozone layer in the stratosphere is thinning.
In some regions it vanishes almost entirely for a few weeks every year.Ozone Depletion – Essay Example Ozone layer is a thin layer that is located within the stratosphere and contains high concentration of ozone.
It protects our planet from the destructive effect of ultraviolet radiation. Here is your essay on ozone layer depletion!
Ozone (O 3) is a triatomic form of oxygen. It is found largely in the stratosphere that extends from about 6 km at the poles and 17 km at the equator to about 50 km above the earth’s surface. It is present in traces less than 1 ppm) in the atmosphere. Essay on Effects of Ozone Layer Depletion.
Article shared by. The upper layer of the atmosphere surrounded by ozone (15 to 30 Kms) is known as ozonosphere. Ozone layer is a protective stratospheric layer, also known as ozone umbrella. What Are The Main Causes Of Ozone Depletion?
Essay on the Effects of Ozone Layer Depletion and its . Depletion of the Ozone Layer: Its causes, effects, and possible solutions Essay Sample The depletion of the ozone layer is a major concern today. The ozone layer protects us from the harmful rays of the sun; therefore it is imperative that we preserve it.
The problems and causes associated with ozone depletion arise from human activities. Unlike pollution which has several causes, there is one specific chemical compound that is responsible for the breakdown of the ozone layer. Solutions to Ozone Layer Depletion.
