  3. Ozone

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

Primary air pollutants are emitted directly into the atmosphere from sources such as industrial processes, combustion engines, and construction activities. Particulate matter is an example of a primary air pollutant.

Multiple choice

What is the term used to describe the process by which air pollutants are transported over long distances?

  1. Advection

  2. Convection

  3. Diffusion

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

Advection refers to the process by which air pollutants are transported over long distances by the movement of air masses.

Multiple choice

Which of the following is an example of a secondary air pollutant?

  1. Carbon monoxide

  2. Nitrogen dioxide

  3. Ozone

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

Secondary air pollutants are formed in the atmosphere through chemical reactions between primary air pollutants. Ozone is an example of a secondary air pollutant, formed by the reaction between nitrogen oxides and volatile organic compounds (VOCs).

  3. Particulate matter

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

Carbon monoxide, nitrogen oxides, and particulate matter are all major types of air pollution that can have adverse effects on human health and the environment.

Multiple choice

Which of the following air pollutants has been linked to cognitive impairment and neurodegenerative diseases?

  1. Carbon monoxide (CO)

  2. Nitrogen dioxide (NO2)

  3. Particulate matter (PM)

  4. Ozone (O3)
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Particulate matter, especially fine particles (PM2.5), has been associated with cognitive decline, increased risk of dementia, and structural changes in the brain.

  1. Green spaces and urban vegetation

  2. Traffic restrictions and car-free zones

  3. Air filters and purifiers

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

Green spaces and urban vegetation, traffic restrictions and car-free zones, and air filters and purifiers have all been shown to improve air quality and reduce cognitive impairment.
