Question

The best method for routine monitoring of air pollution

• A. Sulphur dioxide, smoke, and particulate matter
• B. Sulphur dioxide, Hydrogen sulphide, carbon monoxide
• C. Carbon dioxide, hydrogen sulphide, lead
• D. Sulphur dioxide, Lead and particulate matter

Answer 1

The Correct Option is D

To determine the best method for routine monitoring of air pollution, we need to identify the pollutants most commonly used in such assessments. Air pollution monitoring typically tracks the presence and levels of specific pollutants in the atmosphere that are known to harm human health and the environment. The correct answer points to the monitoring of:

• Sulphur dioxide (SO₂): This is a significant air pollutant resulting from fossil fuel combustion and industrial processes. Monitoring SO₂ levels helps assess air quality and its impact on respiratory health.
• Lead (Pb): Despite reductions in lead emissions, it remains a critical pollutant to monitor due to its toxic effects, especially on children's neurological development.
• Particulate matter (PM): Composed of particles of varying sizes suspended in the air, PM is often monitored to understand the quality of air we breathe. PM₁₀ and PM_2.5 (particles with diameters less than 10 micrometers and 2.5 micrometers, respectively) are significant because they can penetrate the respiratory system, posing serious health risks.

Considering these pollutants is essential for comprehensive air quality monitoring programs aimed at protecting public health and ensuring regulatory compliance. Therefore, the most effective choice for routine air pollutant monitoring includes Sulphur dioxide, Lead, and Particulate matter.
