GRAPH DATA

Annual frequency (%) of the 1 hour average ground-level ozone measurements exceeding the 20 ppb Reference Level for incremental ozone ranges at the Surrey, Langley and Chilliwack GVRD air quality monitoring sites.

Source: Data from Environment Canada, National Air Pollution Surveillance (NAPS) Network, Ottawa, Ontario and GVRD, Burnaby, BC. 2004.

Annual frequency (%) of the average daily PM2.5 measurements exceeding the 15 µg/m3 Reference Level for incremental PM ranges at the Chilliwack, Pitt Meadows and Vancouver GVRD air quality monitoring sites.

Comparison of average percent of time smog pollutant Reference Levels were exceeded in selected Canadian cities and the Fraser Valley.

Source: Environment Canada, 2007.

1 Ozone data (1 hour average) expressed as a percent of time exceeding the Reference Level of 20 ppb and 40 ppb and averaged for the time period of 1994 to 2004.

2PM-2.5 data (24 hour average) measured by TEOM fraction and expressed as a percent of time exceeding the Reference Level of 15 g/m3 for the time period of 2000 to 2004.
