  1. Sulphur dioxide

  2. Nitrogen dioxide

  3. Carbon monoxide

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

Sulphur dioxide, Nitrogen dioxide and Carbon monoxide are criteria pollutants under the Air (Prevention and Control of Pollution) Act, 1981. Particulate matter is not a criteria pollutant under the act.

  2. Bag filter

  3. Catalytic converter

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

Electrostatic precipitator, Bag filter and Wet scrubber are all types of air pollution control devices. Catalytic converter is not an air pollution control device.

Multiple choice

Which of the following is a major contributor to air pollution in urban areas?

  1. Natural gas power plants

  2. Solar energy systems

  3. Wind turbines

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

Motor vehicles, particularly those powered by fossil fuels, emit various pollutants such as nitrogen oxides, particulate matter, and hydrocarbons, contributing significantly to air pollution in urban environments.

Multiple choice

Which of the following is a common air pollutant emitted by coal-fired power plants?

  1. Carbon monoxide

  2. Ozone

  3. Sulfur dioxide

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

Coal-fired power plants emit various air pollutants, including sulfur dioxide (SO2). SO2 is a major contributor to acid rain and can cause respiratory problems in humans and harm ecosystems.

Multiple choice

Which of the following is a major source of particulate matter (PM) air pollution in urban areas?

  1. Industrial emissions

  2. Vehicle exhaust

  3. Construction activities

  4. Residential heating
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Vehicle exhaust is a significant source of particulate matter (PM) air pollution in urban areas. PM includes fine particles and coarse particles, which can cause respiratory problems and other health issues.

Multiple choice

What is the primary air pollutant emitted by natural gas combustion?

  1. Carbon monoxide

  2. Nitrogen oxides

  3. Sulfur dioxide

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

Natural gas combustion primarily emits nitrogen oxides (NOx), which contribute to the formation of ground-level ozone and smog. NOx emissions can also lead to respiratory problems and environmental damage.

Multiple choice

Which of the following is a major source of air pollution in rural areas?

  1. Industrial emissions

  2. Vehicle exhaust

  3. Agricultural activities

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

Agricultural activities, such as the use of fertilizers and pesticides, can contribute to air pollution in rural areas. Ammonia emissions from livestock and nitrogen oxides from fertilizer application can impact air quality.
