1 1 Students type their answers here Primary pollutants are those that are A. Released directly in dangerous forms B. Produced in the greatest quantities C. The most dangerous D. The most threatening to people E. Classified by the EPA as the most dangerous and abundant

2 2 Students type their answers here Fugitive emissions are produced by A. Smokestacks B. Power plants and other heating equipment C. Reactions between pollutants and atmospheric gases D. Strip mining, rock crushing, and other dust- producing activities E. Industry and must go through a smokestack for filtration

3 3 The term NOx is often used because A. There are many different oxides of nitrogen B. It is usually unclear how oxidized nitrogen is C. NO2 and NO easily convert into each other D. Many different molecules often attach to NO E. The pollutant is a nitrous oxide and the "Ox" identifies the oxygen Students type their answers here

D. Volatile organic compounds are produced exclusively by human activity. E. None of these is correct. Students type their answers here

9 9 Which of the following statements is false? A. The likelihood of having radon gas in your home depends largely upon the geology and soil types in your region. B. According to the EPA, toxic air pollutants are generally much more concentrated indoors than outdoors. C. One of the reasons indoor air pollutants are so dangerous is the high amount of time people are indoors. D. In the less-developed countries of Africa, Asia, and Latin America, there is less indoor air pollution than in developed countries. E. All of these statements are true.
