Implicated in human neurological damage

• Sulfur dioxide

• Lead

• Ozone

• Hydrocarbons

• Particulates

Colorless, odorless gas that is a naturally occurring decay product of uranium

• asbestos

• radon

• lead

• carbon monoxide

• formaldehyde

Catalytic converters reduce which of the following pairs of pollutants in car exhaust?

• Carbon dioxide and ozone

• Carbon monoxide and hydrocarbons

• Carbon dioxide and particulates

• Lead and mercury

• Methane and particulates

a secondary pollutant

• forms in the stratosphere

• is transformed by sunlight, water, or other elements in the atmosphere

• cannot be directly tracked to its source

• forms primarily from incomplete combustion

Which is a source of sulfur dioxide found in nature?

• forest fires

• lightning

• plant emissions

• volcano

Thermal inversions

• increase the rate of smog formation

• trap high concentrations of pollution at ground level

• result in increased levels of acid deposition

• reduce the negative effects of VOC's

Acid deposition forms as a result of

• nitrogen oxides and photochemical smog

• carbon monoxide and VOC's

• sulfur dioxide and VOC's

• nitrogen oxides and sulfur dioxides

Which method is used to reduce the nitrogen oxide emissions

• installation of catalytic converters

• increased temperature of combustion

• the use of calcium carbonate to absorb the emissions

• the use of fluidized bed combustion

Which outdoor air pollutant is also a significant indoor air pollutant?

• sulfur dioxide

• carbon monoxide

• ozone

• lead
