2. Definitions
Air:
A mixture of nitrogen, oxygen, and minute amounts of other gases that surrounds the earth and forms its atmosphere;
Archaic. Breath;

3. Major Components

12. Industrial Sources

13. Theoretical Dispersion

14. Smog

16. Dust Storm

17. Air Pollution Control Devices

18. Better AP Control Device

19. Sources of Carbon Monoxide [1999]

20. Hydrocarbon Sources [1999]

21. Nitrogen Oxides {NOX} [1999]

22. Particulates [1999]

23. Auto & Air Pollution

24. A Car commuting 18 miles roundtrip, 5 days/week & 48 weeks/year emmits:
4,500 lbs. of carbon dioxide (CO2)
160 pounds of carbon monoxide (CO)
16 lbs. of volatile organic compounds (VOCs)
16 lbs. of nitrogen oxide (NOx)
Smaller amounts of benzene, formaldehyde, particulate matter and other toxic materials

25. Auto Catalytic Converters
Definition: A substance that causes or speeds a chemical reaction without itself being affected;
Catalysts inside catalytic converters are precious metals such as platinum, palladium, and rhodium coated on the surface of ceramic honeycomb structures.

26. Catalytic Converter

27. Chemical Reactions HC + O2 = H2O + CO2 CO + O2 = CO2 NOX = N2 + O2
SOX = S + O2
C(PM) + O2 = CO2

28. Ozone
Definition: A form of oxygen, O3, produced when an electric spark or ultraviolet light passes through air or oxygen, that in the upper atmosphere absorbs ultraviolet rays, thereby preventing them from reaching the earth's surface, but that near the earth's surface is a harmful irritant and pollutant: used commercially for bleaching, oxidizing, etc.

29. Ozone Creation/ Depletion
Solar Formation
O2 + Sunlight = 2O
O + O2 = O3
Solar Depletion
O3 + Sunlight = O2 + O
O + O3 = 2O2
