B.C. Air Quality

Air Quality Monitoring

Air quality monitoring in British Columbia is conducted by the provincial government, Metro Vancouver, and industry (where required by permit) in cooperation with Environment Canada and regional districts. There are approximately 150 air quality monitoring stations throughout British Columbia. The Network Description page has more detailed information on the provincial air monitoring network.

These stations monitor for a variety of air contaminants, including carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3), particulate matter (PM2.5 and PM10), sulphur dioxide (SO2), and hydrogen sulphide (H2S). The data are reported as raw parameters, and are also used to calculate air quality indexes.
