Causes and Effect of Pollution in Our Environment

INTRODUCTIONThis chapter presents the overview of the topic about the causes and effects of air pollution to our environment. The term air pollution is a mixture of natural and manmade substances in the air we breath such as fine particles produced by the burning of fossils fuel ground level ozone, which is a reactive form of oxygen that is a primary component of urban smog and noxious gases such as sulfur dioxide, nitrogen oxides, carbon monoxide, and chemical vapors. The health effects of air pollution have been reported in research studies over the past 30 years.These effects include respiratory diseases such as asthma, cardiovascular diseases changes in lung development in children.What pollutants affect air quality?What are the causes of air pollution?There are many causes of air pollution examples of these are burning of plastics, vehicles, heavy factories and scattered garbage. These research aims to give and share information and knowledge to the readers regarding to the topic. The purpose of conducting this research is to emphasize on how pollution affects are mankind and the environment. It will also help us to know more about pollution and how we can avoid and save our mother earth. And what are the causes and effects of air pollution.The objectives of these research is to understand the environment and its component to human life, it gives information about the cause and effects brought by the fast spreading of pollution, it also determine the sources of pollution.As the fast moving fluid medium in the environment the atmosphere has always been one of the convenient place to despise of unwanted materials. Ever since we first used fire, the atmosphere has been a sink for waste disposal.Read more: Essay About HazeCHAPTER II
We have to spend a considerable of effort and money to control the major outdoor air pollutants but we have only recently become aware of the danger of indoor air pollutants. The EPA has formed that indoor concentration of toxic air pollutants are often higher than outdoor. Furthermore, people generally spend more time inside than out and therefore are exposed to higher closes of these pollutants. In some cases indoor air in home has chemical concentrations that would be illegal outside or when the workplace. Under some circumstances compounds and styrene can be seventy time higher indoor air than in outdoor in.II. POLLUTION CONTROLFor dater stationary and mobile sources of air pollutants the most reasonable strategies for control have been to reduce, collect, capture or retain the pollutants before they enter the atmosphere. From an environmental view point, the reduction of emissions through energy efficiency and conservation measures, we disease pollutants control for selected air pollutants.A. POLLUTION CONTROL: PARTICULATESParticulates emitted from fugitive, point, or area stationary source are much easier to control than are the very small particulates of primary or secondary origin release from mobile sources, such as automobile. As you learn more about these very small particles, we will have to devise new methods to control them.Particulates from fugitive sources must be controlled or site so the wind does not blow them the atmosphere. Methods include protecting open areas controlling dust, and reducing the effects of wind.B. POLLUTION CONTROL: AUTOMOBILESControl the pollutants such as carbon monoxide, nitrogen oxide and hydro carbon in urban areas is but achieved through pollution control measures for automobiles. Control of this material will also limit ozone formation in the lower atmosphere. Since ozone forms through reaction, with nitrogen oxide and hydrocarbons in the presence of sunlight.Nitrogen oxides from automobile exhaust are controlled by recirculation exhaust gas diluting the air to fuel mixture being burned in the engine. Delusion reduces the temperatures of combustion and decrease the oxygen concentration in the burning mixtures, resulting in the production of fewer nitrogen oxides. Unfortunately the same process increase hydrocarbons emissions. Nevertheless, exhaust the circulation the reduce nitrogen oxide emissions has been common practice in the United States for more than 20 years.C. POLLUTION CONTROL: SULFUR DIOXIDESulfur dioxide emissions can be reducing through basic measures performed before, during or after combustion. Technology to clean up coal so it will burn more cleanly is already available. Although the cause of removing sulfur mix fuel more expensive, the expense must be balanced against the long term consequences of burning sulfur- rich coal.Changing from high- sulfur coal low sulfur coal seems solution to reducing emissions of sulfur dioxide. In some regions, this change will work. Unfortunately most low sulfur coal in the United States is located in the Western part of the country, whereas, must coal is burn in the east. Thus, transportation is an issues use of low- sulfur coal is a solutions only in cases where it is economically feasible.III. GENERAL EFFECTS OF AIR POLLUTION
