Important Air Pollutants

  1. PM2.5 (Fine Particulate Matter)

    • Extremely small particles (less than 2.5 micrometers) that penetrate deep into the lungs and bloodstream.
    • Sources: Traffic emissions, industrial activities, wildfires.
    • Why It Matters: PM2.5 is closely linked to long-term health risks and reduced air quality in urban areas.

  2. PM10 (Coarse Particulate Matter)

    • Larger particles (up to 10 micrometers) that can be inhaled into the respiratory system.
    • Sources: Road dust, construction activities, natural dust from deserts.
    • Why It Matters: PM10 contributes to respiratory issues and environmental degradation.

  3. NO2 (Nitrogen Dioxide)

    • A gas primarily produced by burning fossil fuels, especially from vehicles and power plants.
    • Sources: Road traffic, industrial emissions.
    • Why It Matters: NO2 is a key contributor to smog and acid rain, impacting human health and ecosystems.

  4. O3 (Ground-Level Ozone)

    • A secondary pollutant formed by chemical reactions between NOx and VOCs in sunlight.
    • Sources: Vehicle emissions, industrial activities, and chemical solvents.
    • Why It Matters: Ground-level ozone affects air quality and is particularly harmful during heatwaves.
