Pollutants tied to human and environmental health impacts include PM2.5, PM10, ground-level ozone, nitrogen dioxide and sulfur dioxide. WebThe most common measurement used to measure air quality is PM 2.5 and PM 10. It measures the particles in micrograms per cubic metre. PM 2.5 refers to the concentration of microscopic particles less than 2.5 microns in diameter and PM 10 refers to the concentration of particles less than 10 microns in diameter.
