Recommended 2021 AQG levels compared to 2005 air quality guidelines. µg = microgram ᵃ 99th percentile (i.e. 3–4 exceedance days per year). ᵇ Average of daily maximum 8-hour mean O₃ concentration in the six consecutive months with the highest six-month running-average O₃ concentration.
How AQI is Measured
The AQI is typically measured using the concentrations of five main pollutants:
- Ground-level ozone (O₃)
- Particulate matter (PM2.5 and PM10) – Small particles in the air that can enter the respiratory system.
- Carbon monoxide (CO)
- Sulfur dioxide (SO₂)
- Nitrogen dioxide (NO₂)
