Air Pollution Questions
Which of the following is NOT a primary air pollutant?
-
Carbon monoxide
-
Nitrogen dioxide
-
Ozone
-
Particulate matter
C
Correct answer
Explanation
Ozone is a secondary air pollutant, formed by the reaction of nitrogen oxides and volatile organic compounds in the presence of sunlight.
Which of the following is NOT a criteria pollutant as defined by the U.S. Environmental Protection Agency (EPA)?
-
Carbon monoxide
-
Lead
-
Nitrogen dioxide
-
Ozone
B
Correct answer
Explanation
Lead is not a criteria pollutant, but it is a hazardous air pollutant regulated by the EPA.
Which of the following is NOT a major source of nitrogen dioxide emissions?
-
Power plants
-
Motor vehicles
-
Industrial boilers
-
Residential wood burning
D
Correct answer
Explanation
Residential wood burning is not a major source of nitrogen dioxide emissions, although it can contribute to local air pollution.
Which of the following is NOT a criteria pollutant regulated by the EPA under the Clean Air Act?
-
Particulate matter
-
Sulfur dioxide
-
Volatile organic compounds
-
Carbon dioxide
D
Correct answer
Explanation
Carbon dioxide is not a criteria pollutant regulated by the EPA under the Clean Air Act, although it is a greenhouse gas that contributes to climate change.

-
Power plants
-
Motor vehicles
-
Industrial activities
-
Natural sources (e.g., dust, pollen)
D
Correct answer
Explanation
Natural sources are not a major source of particulate matter emissions, although they can contribute to local air pollution.

-
Motor vehicles
-
Industrial solvents
-
Paints and coatings
-
Natural sources (e.g., trees, plants)
D
Correct answer
Explanation
Natural sources are not a major source of VOC emissions, although they can contribute to local air pollution.

-
Industrial activities
-
Motor vehicles (using leaded gasoline)
-
Residential heating (using leaded fuel)
-
Natural sources (e.g., lead-containing minerals)
D
Correct answer
Explanation
Natural sources are not a major source of lead emissions, although they can contribute to local air pollution.
Which of the following is NOT a major source of mercury emissions?
-
Power plants (burning coal)
-
Industrial activities (e.g., mining, manufacturing)
-
Residential heating (using coal or wood)
-
Natural sources (e.g., volcanic eruptions)
D
Correct answer
Explanation
Natural sources are not a major source of mercury emissions, although they can contribute to local air pollution.
Which of the following is NOT a criteria pollutant under the Clean Air Act?
-
Particulate matter
-
Sulfur dioxide
-
Nitrogen dioxide
-
Carbon monoxide
-
Lead
E
Correct answer
Explanation
Lead is not a criteria pollutant under the Clean Air Act. Criteria pollutants are those for which the Environmental Protection Agency (EPA) has set national ambient air quality standards.
Which of the following is NOT an example of air pollution from construction activities?
-
Dust from excavation and grading
-
Emissions from construction equipment
-
Volatile organic compounds (VOCs) from paints and solvents
-
Noise pollution
D
Correct answer
Explanation
Noise pollution is not an example of air pollution from construction activities. Air pollution is the contamination of the air with harmful substances, such as dust, chemicals, and gases.
What are some ways to reduce air pollution from construction activities?
-
Using dust control measures, such as water sprays and wind screens
-
Using low-emission construction equipment
-
Using paints and solvents with low VOC content
-
All of the above
D
Correct answer
Explanation
All of the above are ways to reduce air pollution from construction activities.
Which of the following is NOT a criteria pollutant under the NAAQS?
-
Particulate matter
-
Sulfur dioxide
-
Nitrogen dioxide
-
Carbon monoxide
-
Lead
E
Correct answer
Explanation
Lead is not a criteria pollutant under the NAAQS. Criteria pollutants are those for which the EPA has set national ambient air quality standards.
Which of the following is NOT a major source of air pollution from industrial activities?
-
Power plants
-
Factories
-
Vehicles
-
Agriculture
D
Correct answer
Explanation
Agriculture is not a major source of air pollution from industrial activities. Power plants, factories, and vehicles are all major sources of air pollution from industrial activities.
Which of the following is NOT an example of an emission control technology?
-
Catalytic converters
-
Scrubbers
-
Electrostatic precipitators
-
Recycling
D
Correct answer
Explanation
Recycling is not an example of an emission control technology. Catalytic converters, scrubbers, and electrostatic precipitators are all examples of emission control technologies.
