Increase Your Air Quality IQ

Air quality affects your health and can change daily or even hourly like the weather.

  • The Air Quality Index (AQI) is a measurement of five air pollutants: ground-level ozone (O3), particle pollution (also known as particulate matter, PM), carbon monoxide (CO), sulfur dioxide (SO2), and nitrogen dioxide (NO2), and tells how clean or polluted the air is.

  • AQI is categorized into levels of health concern and is expressed as a number from 0 to 500 and corresponding color.  See the table below:

    • Readings up to 100 are generally considered satisfactory.

    • The higher the number the worse the air quality.

    • It is best to limit outdoor activities when AQI measurements are high.

  • Older adults, children (including teenagers), and those who have heart and lung conditions can be more sensitive to poor air quality and should take notice of the area AQI.

  • Hanoi AQI readings for PM2.5 and PM10, and SO2 can be found here.

Concordia checks AQI multiple times per day from multiple sources to ensure students are safe.
