Which of the following correctly lists the 6 “criteria” air pollutants as specified under the Clean Air Act?

• Pb, SO₂, NO_X, CO, PM, and tropospheric O₃

• Tropospheric O₃, SO₂, NOX, PM, Pb, and CO₂

• SO₄, NO_X, CO, PM, Pb, and tropospheric O₃

• SO₂, NO_X, CO, Hg, PM, and tropospheric O₃

Which of the following is NOT classified as a primary pollutant?  

• Carbon Monoxide

• Nitrogen Oxides

• Sulfur Dioxides

• Ozone

Ozone is a natural component of the Earth’s stratosphere as well as an element of photochemical smog. Ozone also can be an indoor air pollutant. Sources of ozone in homes or offices include:

•  combustion of fossil fuels

• household solvents and cleaning fluids

• photocopying machines, printers, and other high-voltage electrical equipment  

• electrolysis of tap water

“Scrubbing” is a technique used to:

• collect particulates produced by coal-burning power plants

• control carbon monoxide production in automobiles

• control sulfur emissions in the exhaust from a power plant

• remove carbon dioxide from the exhaust of a power plant
