  • 1. Air Pollution By: Brittani Tague
  • 2.  
  • 3. What is Air Pollution? <ul><li>It is the contamination of the air by lethal gases and minute particles of solid and liquid matter (particulates) in concentrations that endanger health. </li></ul>
  • 4. What contributes to Air Pollution? <ul><li>The major sources of air pollution are transportation engines, power and heat generation, industrial processes, and the burning of solid waste. </li></ul><ul><li>The burning of gasoline and other hydrocarbon fuels in automobiles, trucks, and jet airplanes produces several primary pollutants: nitrogen oxides, gaseous hydrocarbons, and carbon monoxide, as well as large quantities of particulates. </li></ul><ul><li>In the presence of sunlight, nitrogen oxides combine with hydrocarbons to form a secondary class of pollutants, the photochemical oxidants, among them ozone and the eye-stinging peroxyacetylnitrate (PAN). </li></ul><ul><li>Nitrogen oxides also react with oxygen in the air to form nitrogen dioxide, a foul-smelling brown gas. </li></ul>

  • 6. What contributes to Air Pollution? Pt. 2 <ul><li>In cities, air is polluted by transportation and also by the burning of fossil fuels (oil and coal) in generating stations, factories, office buildings, and homes and by the burning garbage. </li></ul><ul><li>The burning produces tons of ash, soot, and other particulates responsible for the gray smog of cities like New York and Chicago, along with enormous amounts of sulfur oxides. </li></ul><ul><li>These oxides rust iron, damage building stone, decompose nylon, tarnish silver, and kill plants. </li></ul>
  • 7. &nbsp;
  • 8. Different types of Air Pollution <ul><li>Ozone </li></ul><ul><li>Smog </li></ul><ul><li>Particle pollution/soot </li></ul>
  • 9. How does Air Pollution effect our health? <ul><li>sulfur oxides=respiratory diseases. </li></ul><ul><li>Acid rain=high levels of sulfuric or nitric acids, can contaminate drinking water and vegetation, damage aquatic life, and erode buildings. </li></ul><ul><li>Indoor air pollution is a problem in developed countries, where insulation keeps pollutants trapped inside . </li></ul><ul><li>In less developed nations, the lack of running water and indoor sanitation can encourage respiratory infections. </li></ul><ul><li>Carbon monoxide drives oxygen out of the bloodstream, causes apathy, fatigue, headache, disorientation, and decreased muscular movements and visual perception. </li></ul>
  • 10. &nbsp;
  • 11. Air pollution in York County <ul><li>York city was actually in the top 25 for worst air pollution according to the American Lung Association but it has subsided a little bit </li></ul><ul><li>66 Pennsylvania counties failed quality air tests for the number of high ozone and particle pollution days </li></ul><ul><li>Soot is the most common type of air pollution in York County and is around all year </li></ul><ul><li>Short-term and long-term pollutants remain unhealthy for more than 400,000 residents living in and around York City </li></ul><ul><li>Coal plants are the largest contributors to particle pollution, ozone, mercury and global warming </li></ul>
  • 12. What can we do to eliminate some air pollution? <ul><li>Tighter regulations made- EPA increased standards and required industry to clean up its act. </li></ul><ul><li>limit exposure to pollutants </li></ul><ul><li>making sure living areas are well ventilated when using coal and wood during cool months </li></ul><ul><li>avoiding cigarettes and other forms of smoke </li></ul><ul><li>reducing pollutants by driving less </li></ul><ul><li>not burning wood or trash and making repairs to things such as vehicles and furnaces </li></ul>
  • 13. Works Cited <ul><li>“ 50 Tips To Prevent Air Pollution.” www.kirotv.com. Green Living. 1 Mar. 09. </li></ul><ul><li>Bellin, Peter. Environmental Impact of Air. 12 Feb. 2009 </li></ul><ul><li>http://www.csun.edu/~hchsc00b/468/468WK8.pdf </li></ul><ul><li>Morrison, Blake, and Brad Heath. Toxic air and America’s Schools/Health Risks </li></ul><ul><li>Stack Up. 08 Dec 2008. 2 Feb 2009 www.ebscohost.com </li></ul><ul><li>Socha, Tom. “Air Pollution Causes and Effects.” 11 Sept. 2007.28 Feb. 2009 </li></ul>
