  4. Sulfur dioxide (SO2)
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Particulate matter, especially fine particulate matter (PM2.5), is strongly associated with increased risk of premature death. PM2.5 particles can penetrate deep into the lungs and cause inflammation and irritation, leading to increased risk of cardiovascular disease, respiratory problems, and other health issues.

Multiple choice

What is the primary air pollutant released during diorite quarrying?

  1. Carbon monoxide

  2. Sulfur dioxide

  3. Nitrogen oxides

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

Diorite quarrying generates large amounts of dust, which can contain harmful particulate matter. This particulate matter can be inhaled by humans and animals, leading to respiratory problems and other health issues.

Multiple choice
