Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Industrial activities, such as manufacturing, mining, and power generation, release pollutants like particulate matter, sulfur dioxide, and nitrogen oxides into the atmosphere.

Multiple choice

Which of the following is NOT a primary source of particulate matter (PM) pollution?

  1. Vehicle exhaust

  2. Industrial emissions

  3. Construction activities

  4. Natural sources (e.g., dust, sea salt)
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Natural sources, such as dust and sea salt, are not primary sources of particulate matter pollution, as they occur naturally and are not directly caused by human activities.
