1. Chapter 20 Air Pollution

2. Atmosphere Structure

3. Primary and Secondary Pollutants

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

6. Temperature Inversion

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?
