Not a primary pollutant: particulate matter, ozone, sulfur oxide, volatile organic compounds
What is ozone?
100
A substance that is colorless, tasteless, and odorless radioactive gas: asbestos, carbon monoxide, radon, ozone.
What is radon?
100
Vehicles that have no tailpipe emissions, no emissions from gasoline, and no emission-control systems.
What is a zero-emission vehicle?
200
Smog
What is air pollution that hangs over urban areas and reduces visibility?
200
Secondary pollutant
What is a pollutant that is formed when a primary pollutant reacts with another primary pollutant or a naturally occurring substance (water vapor)?
200

300
pH
What is the measure of how acid or basic a substance is? less than 7.0 is acid; greater than 7.0 = base
300
