Air contamination - Research Paper ExampleCurrently, automobiles are the largest contributor to the formation of ground take aim ozone therefore there is a need to increase usage of alternative sources of transportation in order to reduce levels of O3 air pollution.Air pollution has sire a major environmental health problem affecting both developed and developing countries throughout the world (Nadakavukaren, 2006). The consequence has been that air pollution is create human health problems as well as damage to vegetation, crops, wildlife, materials, buildings and even the climate. In the U.S., the largest sources of air pollution, in order of importance, are 1) transportation, mainly automobiles and trucks 2) electric position plants that bum coal or oil and 3) industry, for which the major sources include steel mills, metal smelters, oil refineries, and paper mills (Nadakavukaren, 2006). The most common air pollution problem resulting from these emission sources is ground-leve l ozone (O3), According to the United States Environmental Protection Agency (EPA), non-attainment of EPA requirements for O3 is the most common air pollution problem facing large cities in the U.S (Crpc-La.org, 2011). It is estimated that, 160 million people in the U.S. lived in areas that are in non-attainment of healthful O3 levels (Organization for Economic Co-operation and Development OECD, 2005).In the past, efforts to reduce air pollution attain consisted primarily of command and control programs that involve enforcement of government regulations designed to reduce toxic emissions. Such programs have proven highly effective in step-down industrial, point source pollution and causing auto manufacturers to produce cleaner burning automobiles (Environmental Protection Agency EPA, 2011a). While these government controls continue to effectively raze industrial emissions and reduce pollutants emitted from vehicles, O3 precursor, NOx, continues to be emitted into the air at incre asing levels.
