How Air Pollution Is Measured (cont.)

• Broken down into categories (cont.)

• • PM10/PM2.5 — Particulates (the number is diameter in microns) — “dust”
  • • PM2.5 especially penetrates deep into the lungs
    • Other air pollutants (e.g. VOCs) adhere to particulates, so particulates:
    • • Are the pathway for air pollution deep into the lungs
      • Magnify the dosage of other air pollutants
  • Formaldehyde — causes acute symptoms, is carcinogenic
  • SOx — sulfur oxides
