What is the purpose of the National Ambient Air Quality Standards (NAAQS)?

  1. To protect public health and welfare from harmful air pollutants

  2. To regulate emissions from industrial sources

  3. To set limits on the amount of air pollution that can be released into the atmosphere

  4. To monitor air quality in urban areas

Show answer
Correct Option: A
Explanation:

The NAAQS are designed to protect public health and welfare by setting limits on the amount of certain air pollutants that can be present in the ambient air.

Which agency is responsible for setting and enforcing the NAAQS?

  1. Environmental Protection Agency (EPA)

  2. National Oceanic and Atmospheric Administration (NOAA)

  3. Occupational Safety and Health Administration (OSHA)

  4. Food and Drug Administration (FDA)

Show answer
Correct Option: A
Explanation:

The EPA is responsible for setting and enforcing the NAAQS under the Clean Air Act.

What are the six criteria pollutants regulated by the NAAQS?

  1. Carbon monoxide (CO), lead (Pb), nitrogen dioxide (NO2), ozone (O3), particulate matter (PM), and sulfur dioxide (SO2)

  2. Carbon monoxide (CO), lead (Pb), nitrogen dioxide (NO2), ozone (O3), particulate matter (PM10), and sulfur dioxide (SO2)

  3. Carbon monoxide (CO), lead (Pb), nitrogen dioxide (NO2), ozone (O3), particulate matter (PM2.5), and sulfur dioxide (SO2)

  4. Carbon monoxide (CO), lead (Pb), nitrogen dioxide (NO2), ozone (O3), particulate matter (PM10 and PM2.5), and sulfur dioxide (SO2)

Show answer
Correct Option: D
Explanation:

The six criteria pollutants regulated by the NAAQS are carbon monoxide (CO), lead (Pb), nitrogen dioxide (NO2), ozone (O3), particulate matter (PM10 and PM2.5), and sulfur dioxide (SO2).

What is the difference between primary and secondary NAAQS?

  1. Primary NAAQS are set to protect public health, while secondary NAAQS are set to protect the environment

  2. Primary NAAQS are set to protect the environment, while secondary NAAQS are set to protect public health

  3. Primary NAAQS are set to protect public health and the environment, while secondary NAAQS are set to protect public health only

  4. Primary NAAQS are set to protect public health only, while secondary NAAQS are set to protect public health and the environment

Show answer
Correct Option: A
Explanation:

Primary NAAQS are set to protect public health by limiting the amount of air pollution that can be present in the ambient air, while secondary NAAQS are set to protect the environment by limiting the amount of air pollution that can cause damage to plants, animals, and ecosystems.

What is the difference between a violation of the NAAQS and a nonattainment area?

  1. A violation of the NAAQS occurs when the concentration of a pollutant in the ambient air exceeds the NAAQS for that pollutant, while a nonattainment area is an area where the NAAQS have not been met

  2. A violation of the NAAQS occurs when the concentration of a pollutant in the ambient air is below the NAAQS for that pollutant, while a nonattainment area is an area where the NAAQS have been met

  3. A violation of the NAAQS occurs when the concentration of a pollutant in the ambient air is equal to the NAAQS for that pollutant, while a nonattainment area is an area where the NAAQS have been exceeded

  4. A violation of the NAAQS occurs when the concentration of a pollutant in the ambient air is greater than the NAAQS for that pollutant, while a nonattainment area is an area where the NAAQS have been violated

Show answer
Correct Option: A
Explanation:

A violation of the NAAQS occurs when the concentration of a pollutant in the ambient air exceeds the NAAQS for that pollutant, while a nonattainment area is an area where the NAAQS have not been met and the air quality is considered to be unhealthy.

What are some of the health effects associated with exposure to air pollution?

  1. Asthma, heart disease, stroke, and cancer

  2. Common cold, flu, and allergies

  3. Headaches, fatigue, and nausea

  4. Skin rashes and eye irritation

Show answer
Correct Option: A
Explanation:

Exposure to air pollution has been linked to a number of health effects, including asthma, heart disease, stroke, and cancer.

What are some of the sources of air pollution?

  1. Motor vehicles, power plants, and industrial facilities

  2. Natural sources such as volcanoes and forest fires

  3. Indoor sources such as tobacco smoke and cleaning products
