Multiple choice

Which of the following is NOT a major source of air toxics?

  1. Motor vehicles

  2. Industrial facilities

  3. Power plants

  4. Natural sources
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Natural sources, such as volcanoes and forest fires, do not emit significant amounts of air toxics.

Multiple choice

Which of the following is NOT an example of an air toxic?

  1. Carbon monoxide

  2. Lead

  3. Benzene

  4. Mercury
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Carbon monoxide is not an air toxic, as it is not classified as a hazardous air pollutant by the US Environmental Protection Agency (EPA).

Multiple choice

Which of the following is NOT a common method of air toxics control?

  1. Filtration

  2. Adsorption

  3. Incineration

  4. Dilution
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Dilution is not a common method of air toxics control, as it does not remove air toxics from the air, but rather disperses them over a larger area.

Multiple choice

Which of the following is NOT a major air toxic emitted by motor vehicles?

  1. Benzene

  2. Formaldehyde

  3. Carbon monoxide

  4. Lead
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Carbon monoxide is not a major air toxic emitted by motor vehicles, as it is not classified as a hazardous air pollutant by the EPA.
