3. Sources include: Cigarette smoke Formaldehyde Radon Bacteria, viruses, mold, dust mites, pollen Carbon monoxide Asbestos Indoor Air Pollution

4. As an indoor air pollutant, this pollutant is an asphyxiant at high concentrations and can kill unsuspecting people through suffication CO (Carbon Monoxide)

5. VOCs (Volatile Organic Compounds)

6. Primary Pollutants

7. Sources of this indoor pollutant include: Plywood Particle board Wallpaper Furniture Draperies Carpeting Formaldehyde

8. This primary pollutant can combine with water vapor in the atmosphere and form weak sulfuric acid SO 2 (Sulfur Dioxide)

9. Particulate Matter

10. SO 3 (Sulfur trioxide) NHO 3 (Nitric Acid) H 2 SO 4 (Sulfuric Acid) O 3 PANS NO 3 ─ salts SO 4 2─ salts Secondary Pollutants

11. Radon gas

12. Even though this molecule is a pollutant in the troposphere, it is actually very beneficial in the stratosphere O 3 (Ozone)

13. Primary air pollutant released from the combustion of fossil fuels; can be removed from smoke stacks using wet scrubbers SO 2 (Sulfur Dioxide)

14. Air pollutants that are released directly from their source into the atmosphere Primary Pollutants

15. Indoor Air Pollution

16. Seeps into buildings from underground deposits; it is a decay product of radioactive uranium, radium, or thorium Radon gas

17. Photochemical Smog Cities built in valleys and areas surrounded by mountains are subject to temperature inversions that trap air pollutants.

18. Formaldehyde

19. Air pollutants that form as the products of chemical reactions that occur among primary pollutants and other chemicals present in the atmosphere Secondary Pollutants

20. This primary pollutant can be a solid or liquid and is emitted from coal fired power plants, agricultural field work operations, tobacco smoke and motor vehicle exhaust Particulate Matter

21. VOCs (Volatile Organic Compounds)

22. Primary pollutant that is a product of incomplete combustion reactions during the burning of fossil fuels CO (Carbon Monoxide)

23. Most common sources include: Xylene Ethylene Benzene Toluene These chemicals create ground level ozone and prolong the life of methane in the atmosphere VOCs (Volatile Organic Compounds)

24. Secondary air pollutant that is a major component of photochemical smog O 3 (Ozone)

25. Photochemical Smog

26. CO CO 2 SO 2 NO NO 2 VOCs Primary Pollutants

27. When inhaled, the alpha particles can damage lung tissues and other tissues of the respiratory tract which can increase the risk for lung cancer Radon gas

28. Secondary Pollutants

29. Symptoms of this indoor air pollutant include: Headache Respiratory irritant Eye irritant Sore throat Skin rashes Dizziness Nausea Cancer Formaldehyde

30. The majority of people in developed countries have jobs that keep them indoors. Due to poor ventilation, this accumulates and increase in concentration and can reach unhealthy levels very quickly Indoor Air Pollution

31. Photochemical Smog

32. This unstable molecule is a strong oxidant and readily reacts to shed an oxygen atom to become a more stable molecule. O 3 (Ozone)
