Air quality

Pollutants we monitor

Objectives have been set by the government, for the following pollutants:

  • Ground Level Ozone (O3)
  • Benzene
  • 1, 3 Butadiene
  • Lead
  • Carbon Monoxide (CO)
  • Nitrogen Dioxide (NO2)
  • Sulphur Dioxide (SO2)
  • Particulate Matter less than 10 microns in diameter (PM10) and Polycyclic
  • Aromatic Hydrocarbons (PAH)

Note: Ozone and Aromatic Hydrocarbons remain as national objectives not prescribed in regulation and presently remain outside the scope of local air quality management.

Objectives have been set at levels for which there would be no or extremely low risk to health.
