Presentation Transcript


1. Which of the following pollutants will cause the most damage to the lungs when inhaled?

  • SO2

  • NO2

  • O3

  • Pb


2. What is a NAAQ?

  • A division of the EPA that regulates air pollution

  • An air quality standard

  • A class of toxic indoor air pollutants

  • The ability to do something naturally


3. Which of the following laws regulate air pollutants such as SOx and NOx?

  • Montreal Protocol

  • Kyoto Protocol

  • Clean Air Act

  • Healthy Skies Initiative


4. What does a catalytic converter do?

  • It converts O3 to O2.

  • It removes particulates from coal plant emissions.

  • It converts NO2 to N2O.

  • It reduces CO and hydrocarbon emissions from cars.


A catalytic converter performs a series of reactions that convert CO into CO2 and completes the combustion of unburned HC’s (reduces VOC emissions). A 3-way catalytic converter also breaks down nitric oxides (NOx) into N2 (Not N2O – which is a very strong greenhouse gas).


5. What fibrous material was used as fireproofing material and causes lung cancer?

  • Formaldehyde

  • Asbestos

  • Trichloroethane

  • Radon-222


6. Where does Radon-222 come from?

  • Outgassing of toxic gases in building materials.

  • Groundwater contamination.

  • Decay of Uranium minerals in the ground.

  • Photochemical reactions in the atmosphere.


7. Persistent swelling of the bronchi and bronchioles within the lungs best describes which condition?

  • Asthma

  • Emphysema

  • Chronic bronchitis

  • Lung cancer


Emphysema destroys the walls of the alveoli of the lungs, resulting in a loss of surface area available for the exchange of oxygen and carbon dioxide during breathing. This produces symptoms of shortness of breath, coughing, and wheezing. In severe emphysema, difficulty in breathing leads to decreased oxygen intake, which causes headaches and symptoms of impaired mental ability.
