Air Pollution :: essays research papers

Air PollutionAir, is the most essential element for all life history organisms and yet, most humans play a full-size role on polluting this essential resource. Air pollution may not be as monstrous in its direct outcome as nuclear or water pollution can be, but in the long term it will do an tremendous effect on the environment and health of its organisms living in. Asthma, cancer, acid rain, and the disability to photosynthesize argon only a few causes of air pollution.The atmospheric pollutants with the sterling(prenominal) effect onto the environment are the simple machinebon monoxide, carbon dioxide, hydrocarbons, sulfur dioxide, nitrogen oxides, dust particles, radioactive isotopes, and chlorofluorocarbons. The major sources that enable carbon monoxide to enter the atmosphere are the exhausts of cars, the burning of fossil fuels, and the oxidation of natural methane. Carbon dioxide is caused by the consumption of fossil fuels only and it causes the possible greenhouse ef fect which has global warming as an outcome. Hydrocarbons are caused by the combustion of oil and petrol and it effects the environment with carcinogen. Carcinogen is a chemical agent that causes cancer. Sulphur dioxide is certainly one of the major atmospheric pollutants considered that it causes stinging eyes, lung damage, asthma, and acid rain. It is the result of coal-fired power stations. Nitrogen oxides that is produced by the exhaust of cars, causes pneumonia and asphyxia. The outcome of the well known dust particles is often underestimated. It is caused by industrial chimneys, car exhaust, and volcanic eruptions and it effects the environment by toxic effects and damage of the lungs. Radioactive isotopes which are caused by small quantities from nuclear counteract and nuclear accidents submit an carcinogenic effect on the environment as well. The outcome of chlorfluorocarbons, which had been first discovered in the 80s is that it destroys the ozone layer. Many of those maj or atmospheric pollutants combined produce the serious and well known smoke and gas emission called smog.Smog or dust dome is most often formed when a layer of calm down air is trapped beneath a layer of still warmer air. The mixture of benzopyrene ( a cancer causing substance that is produced by the evaporation of petrol), the waste of hydrocarbons, combined with nitrogen dioxide, oxygen, and sunlight produce the photochemical smog which can be recognized as the yellow cloud over every big city in the world. Besides that optical effect it causes an increase of ozone in the lower atmosphere and the health conditions of the particular organism living in such(prenominal) an area.
