1. A flammable greenhouse gas produced by ruminants, rice paddies and landfill decompostion. Methane

2. NOT a source for CFCs: • Leaking air conditioners • Burning fossil fuel • Some spay can propellants B. Burning fuel does not release chlorines

3. The most abundant gas in the troposphere. nitrogen

4. Which would be most effective in decreasing acid rain deposition? • Add lime to acidified lakes. • Use higher smoke stacks. • Reduce use of fossil fuels. C. Reduce burning of fossil fuels

5. Which of the following is released by CFC’s and catalyzes a reaction that breaks down ozone? • Chlorine • Carbon dioxide • Sulfur dioxide A. Chlorine

6. Naturally occurring air pollutant that causes lung cancer. • Methane • Carbon monoxide • Radon C. Radon

7. Air pollutant that is implicated in human neurological damage. • Particulates • Lead • Ozone B. Lead

8. Photosynthesis is the major source of this gas in the troposphere: Oxygen

9. Particulates can be removed from stack exhaust gases by all of the following methods EXCEPT: A. baghouse filters B. wet scrubbers C. taller smokestacks C. Taller smokestacks

10. The protective ozone layer is located in this layer of the atmosphere: Stratosphere

11. One of these is NOT a secondary pollutant: • Nitrous oxide • Carbon monoxide • Peroxyacyl nitrates (PANs) B. Carbon monoxide is primary

12. Air pollution that is a mixture of primary and secondary pollutants under the influence of sunlight. Photochemical smog

13. These currently help to moderate the earth’s average temperature by removing about 29% of the excess carbon dioxide: Oceans

14. The release of this pollutant is a good example of positive feedback – it contributes to global warming which results in the release of more of this gas...... Methane

15. What would most directly explain the periodic fluctuation of the curve? Seasonal photosynthetic activity

22. The type of rock/soil most sensitive to acid deposition. Granite

23. Natural precipitation should have a pH of 5.6

24. One of the following is NOT an effect of acid deposition: • Contribute to the release of metals that are highly toxic. • Damage statues and buildings. • Acid shock that kills fish. You knew there had to be one trick question. This is it. They are all effects.

25. According to the EPA, the most dangerous three indoor air pollutants are: Cigarette smoke Formaldehyde Radon

26. Name That Pollutant – must have all three correct: • 88% from coal burning power plants, colorless and irritating, major contributor to acid rain. • Colorless and odorless, in cigarette smoke and incomplete combustion. • Reddish-brown, converts to an acid in the atmosphere, 50% from vehicle emissions.

27. Correct answers are: • Sulfur dioxide • Carbon monoxide • Nitrogen dioxide
