Presentation Transcript

  1. Chapter 20 Air Pollution

  2. Atmosphere Structure http://www.nasa.gov/centers/langley/images/content/124546main_ozone-in-layers.jpg

  3. Primary and Secondary Pollutants http://www.pepa.com.hk/problems/air_pollution/images/pic1.jpg

  4. Carbon Dioxide: Pollutant? • At a high enough concentration, any chemical can be considered a pollutant • We are increasing the concentration of CO2 in our atmosphere • The troposphere is warming and there is evidence that the additional CO2 is contributing to the warming.

  5. Photochemical Smog http://www.ems.psu.edu/~lno/Meteo437/Smog1.jpg

  6. Temperature Inversion http://www.globalchange.umich.edu/gctext/Inquiries/Inquiries_by_Unit/Unit_9_files/image007.jpg

  7. Asian Brown Cloud

  8. Sulfur Oxides • What do sulfur oxides become once they are released into the atmosphere? • What effects can it have on the environment? • What do you think is the trend for this polluted has been over the last 20 years?
