20 Air Pollution Issues

21 The Atmosphere as a Resource Atmospheric composition: Nitrogen = 78% Oxygen = 21% Argon = 0.93% Carbon dioxide = 0.04%

22 Types and Sources of Air Pollution Primary and Secondary Air Pollutants

23 Types and Sources of Air Pollution Primary Air Pollutants

24 Types and Sources of Air Pollution Sources of Outdoor Air Pollution

25 Urban Air Pollution

26 Types and Sources of Air Pollution Case-in-Point: Air Pollution in Los Angeles and Mexico City Sources of smog in Los Angeles

27 Controlling Air Pollution in the United States Clean Air Act Emissions in the US, 1970 vs. 2000

28 Air Pollution Around the World Many nations do not have most current pollution scrubbing technologies Air pollution in China

29 Air Pollution Around the World Long-Distance Transport of Air Pollution: Global Distillation Effect

30 Indoor Air Pollution

31 Radon Carcinogen
