Automobile Air Pollution Essay Example for Free

Automobile Air Pollution EssayEfforts to advance the standard of living for humans, through the control of nature and the development of untested products have also resulted in the befoulment of the environment. Much of the worlds circularize, water, and land is now partially poisoned by taint. Some places have become uninhabitable. This pollution exposes tidy sum all around the globe to new risks from sickness. Many species of plants and animals have become endangered or atomic number 18 now extinct. The disperse pollution comes from lots of sources but the paper will be rough air pollution cause by autos. As a result of tremendous amount of air pollution, primarily for automobile governments have passed laws to limit or reverse the threat of environmental pollution. There are lots of sources other than the automobile for air pollution. Nature itself is one of the causes. Sometime nature causes the air pollution by activities like a forest fire, volcanic, hurricane. T hese are temporary dislocations that nature balances and accommodates to modern economic development, however, more(prenominal) or lesstimes disrupts natures delicate balance. The other source is from factories. Factories are release crappers and chemic in the air.In some places potbelly from factories and cars conflates with naturally occurring fog to form smog and create a midday sky. It had happened in London, London, England, has been subjected to the danger of smog, abundant recognized as a potential cause of death, especially for elderly persons and those with severe respiratory ailments (pollution). theodolite by car though, is the major source of air pollution. Early in the century human invented, inbred combustion engine, engine that use fuel as gasoline or relegatesel. Those engines were used to manufacture an automobile for fast travel from one place to another.Because they were not much in use, those few cars were not exuberant to threat the environment. Thos e engines were not fast enough so mastermind humans invented bangingger and faster engines and those sire more fuel. When these engines cut down fuels they introduce smoke and other, less visible, by products. Once they are released into the air, the products of incomplete combustion, particulate matter (soot, ash, and other solids), unburned hydrocarbons, carbon monoxide, sulfur dioxide, various nitrogen oxides, ozone, and extend, undergo a series of chemical reactions in the presence of sunlight.The result is the dense haze characteristic of smog. Smog may appear chocolate-brown in color when it contains high concentrations of nitrogen dioxide, or it may look blue-gray when it contains large amounts of ozone (Danger). The cumulative perfume of air pollution poses a grave threat to humans and the environment. Smog causes number of children and elderly to die because children lungs are still developing, also they breath more rapidly than adults, and they play outdoor. Most el derly people loose the red cells that cause diseases to go out of control.That lead them to the development of chronic lung diseases. The costs of air pollution are enormous. The American Lung Association sites sulfur-dioxide exposure as the third leading cause of lung disease after active and passive smoking (Justification) Air pollution does not only cause health hazard but also cause acid rain to fall. astringent rain causes damage to bodily structure or life. Plants and animal marine animal are most effected by acid rain. venereal infection rain or snow pollute the water and soil the major source for plants and marine species to survive.Acid rain or snow falls when sulfur dioxide emissions from exhaust of an internal combustion engine combine with particles of water in the atmosphere. In Canada, Scandinavia, and the northeastern United States, acid rain is blamed for the deaths of thousands of lakes and streams (Acid rain). Another new and troubling form of air pollution co mes from a variety of chemicals called chlorofluorocarbons, also known as CFCs. For many long time it was used by automobile industries.These chemicals were used in the air conditioning systems of the car. CFCs takes decade to discombobulate in the upper atmosphere but when it gets there it combines with other molecules. Then, by attaching themselves to molecules of ozone, CFCs transform and destroy the hold dearive(p) ozone layer. The result has been a sharp decline in the amount of ozone in the stratosphere. At ground level, ozone is a threat to our lungs, but in the upper atmosphere ozone works as a shield to protect against ultraviolet beam from the sun (Ozone).If the ozone shield gets too thin or disappears, exposure to ultraviolet radiation can cause crop failures and the spread of epidemic diseases, skin cancer, and other disasters. The automobile has a big impact on over our environment. Today we have trillions of automobiles on the road. Each car produce smoke and chemic als that hazardous to our world. Sometimes people take that threat seriously and they try to find solution. It is necessary to burn fuel completely because unburn fuel release more chemicals than burned fuel.Most new cars have deuce group O sensors that monitor and control the burning of fuel (Toyota Eng. ). I think problem is that as oxygen sensors age, their warm-up response slows considerably. withal government says, The major cause of air pollution is the internal-combustion engine of automobiles. gaseous state is neer completely burned in the engine of a car, just as coal is never completely burned in the furnace of a steel mill (EPA). Other than two oxygen sensors some engineers came up with electric. These cars are good for our environment because they do not use gasoline as fuel.Even they dont produce any smoke. It has some problem with it too like electric cars need to recharge more often and the are not fast enough. The other problem is that after while the batteries n eeds to replace. You figure if trillion cars need to replace batteries than it will fill our safe chemical deposal sites in few years than we have more chemical waste in our environment. The solar cars are not that bad in the futuristic problems but cars arent fast enough. Air pollution has been the target of some of the most complicated and far-reaching edict ever enacted.In 1970, the United States Congress passed legislation aimed at curbing sources of air pollution and reach standards for air quality. A few years later, Congress passed laws designed to phase out the use of lead as an additive in gasoline (EPA). That helped us because the level of lead in the average Americans bloodstream has declined. We still didnt do much about cause of acid rain and it is continually debated in northwestern America and throughout Europe. In late 1987, more than 20 nations signed an agreement to limit the output signal of CFCs and to work toward their eventual elimination (EPA).
