PM2.5 data is reported in units of micrograms per cubic meter (µg/m3) and should adhere to the World Health Organization (WHO) guidelines implemented in 2021. Examples of PM2.5 include sulphates, black carbon, nitrates, and ammonium.
Fort St. John had a PM2.5 rating of 18.7 µg/m3, far exceeding the WHO’s recommended rating of 5.
The top ten cities with the worst air quality in North America were all based in Canada, marking the first time Canada had surpassed the United States in terms of air pollution.
Wildfires burning throughout the country in 2023 were the most contributing reason, said IQ Air.
