Update on wiki article

Hey! Check the changes I have made to the article 'Mobile Source Air pollution' under discussion section. We have to keep this going and invite our mentors to provide suggestions. --Swgarg (talk) 00:14, 21 February 2011 (UTC)

Summary for article

There is a definite difference between mobile and stationary sources of air pollution. For example, mobile sources include cars and aircraft while stationary sources include factories and power plants. Mobile sources can also be classified as “on-road” and “non-road” sources of air pollution. It is important to differentiate between these different sources because the EPA handles them differently, thus there are a number of different policy tools that are used for regulation.

Some specific air pollutants pose threats to human and environmental health. Those pollutants include carbon monoxide, carbon dioxide, nitrous oxides, hydrocarbons, and particulate matter. Environmental effects include smog production, ozone depletion, and global climate change as a result of greenhouse gasses. Human health effects include reduced oxygen availability for organs, reduced cardiovascular function, and asthma. Each of these pollutants is generated by mobile sources and the EPA has realized that it is important to reduce their ambient air concentrations.
