Why is it necessary to distinguish pollutant particles from natural dust in the atmosphere?
Answer and explanation
Correct answer: Because their sources, chemical properties and health effects can differ
Natural dust may arise from soil, minerals or deserts, whereas pollutant particles can come from combustion, industry, traffic and chemical reactions in air. Their size and composition determine visibility, climate influence, toxicity and respiratory risk. Therefore source identification is important for monitoring and control. Option A is correct; B, C and D make absolute claims that are false.
