  1. What is air pollution? “The contamination of the atmosphere by

    noxious gases and particulates.” May be divided into outdoor and indoor.
  2. Sulfur oxides Come from volcanic eruptions (mostly harmless). Come from

    industrial processing (extremely toxic). Used as disinfectants, refrigerants, and preservatives.
  3. Nitrogen dioxide Used to make rocket fuels and explosives. Present

    in car exhaust, electric power plants, the burning of fuels, and cigarettes. Can be toxic.
  4. Carbon monoxide Produced while burning fuel. Present in vehicle exhaust

    and cigarette smoke. Highly toxic and potentially lethal.
  5. Ozone Created in a reaction between nitrogen dioxide and hydrocarbons.

    Pollutant in the troposphere, but essential in the stratosphere.
  6. Particulate matter Refers to any particles in the air. Come

    from burning fuels, volcanoes, and construction sites. May accumulate in the lungs and become harmful.
  7. Top five ways to help Drive less. Plant more. Help

    eliminate dust (avoid creating large dirt patches). Be mindful of your use of the air conditioner/heater.
