Multiple choice

Which of the following air pollutants is a major cause of respiratory problems, including asthma and bronchitis?

  1. Carbon monoxide (CO)

  2. Nitrogen dioxide (NO2)

  3. Ozone (O3)

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

Particulate matter (PM), particularly fine particles (PM2.5), is a major cause of respiratory problems due to its ability to penetrate deep into the lungs and cause inflammation.
