  1. Greenhouse gas

  2. Oxidizing agent

  3. Aerosol precursor

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

NO2 acts as a greenhouse gas, an oxidizing agent, and an aerosol precursor in the atmosphere.

Multiple choice

Multiple choice

Which of the following is a primary air pollutant emitted by chemical manufacturing processes?

  1. Sulfur dioxide

  2. Nitrogen oxides

  3. Volatile organic compounds (VOCs)

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

VOCs are emitted during the production and use of chemicals, solvents, and paints, and contribute to the formation of ground-level ozone and smog.

Multiple choice

Which of the following is a common air pollution control technology used in chemical manufacturing to reduce VOC emissions?

  1. Electrostatic precipitators

  2. Fabric filters

  3. Catalytic converters

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

Thermal oxidizers destroy VOCs by burning them at high temperatures.

  1. 0.03 ppm

  2. 0.1 ppm

  3. 0.5 ppm

  4. 1.0 ppm
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The NAAQS for SO2 is set at 0.03 ppm (parts per million) averaged over a 1-hour period.

Multiple choice

Which of the following air pollutants is primarily responsible for acid rain?

  1. Carbon monoxide

  2. Nitrogen oxides

  3. Sulfur dioxide

  4. Particulate matter
Reveal answer Fill a bubble to check yourself
