Air quality: annexes

Air quality problems such as smog and acid rain result from the release of pollutants into the atmosphere. The majority of these pollutants come from human activities, such as transportation, the burning of fuels for electricity and heating, and industry. Natural sources such as forest fires can sometimes be substantial. Air pollutants cause adverse health and environmental effects.

The Air quality indicators present the annual averages of 5 key air pollutants for Canada and 5 large regions. Comparison of the averages to the Canadian Ambient Air Quality Standards (the standards) is for illustrative purposes only. An average that is below the standards does not imply that air pollutant levels are below the standards in all areas of Canada. Please consult the Canadian Council of Ministers of the Environment State of the air report for information on how air pollutant levels in areas of Canada compare to the standards.

Column Description
NAPS ID National Air Pollution Surveillance monitoring station identifier. Please consult the National Air Pollution Surveillance Data Products web page for the location and parameters of the National Air Pollution Surveillance stations.
Average fine particulate matter The station contributes data to the time series trend analysis for annual average fine particulate matter in the national indicator and regional indicator of the identified region, unless the cell contains n/a (not available).
Peak fine particulate matter The station contributes data to the time series trend analysis for annual peak (98th percentile) 24-hour fine particulate matter in the national indicator and regional indicator of the identified region, unless the cell contains n/a (not available).
Average ozone The station contributes data to the time series trend analysis for annual average ozone in the national indicator and regional indicator of the identified region, unless the cell contains n/a (not available).
Peak ozone The station contributes data to the time series trend analysis for annual peak (4th-highest) 8-hour ozone in the national indicator and regional indicator of the identified region, unless the cell contains n/a (not available).
Average sulphur dioxide The station contributes data to the time series trend analysis for annual average sulphur dioxide in the national indicator and regional indicator of the identified region, unless the cell contains n/a (not available).
Peak sulphur dioxide The station contributes data to the time series trend analysis for annual peak (99th percentile) 1-hour sulphur dioxide in the national indicator and regional indicator of the identified region, unless the cell contains n/a (not available).
Average nitrogen dioxide The station contributes data to the time series trend analysis for annual average nitrogen dioxide in the national indicator and regional indicator of the identified region, unless the cell contains n/a (not available).
Peak nitrogen dioxide The station contributes data to the time series trend analysis for annual peak (98th percentile) daily maximum 1-hour nitrogen dioxide in the national indicator and regional indicator of the identified region, unless the cell contains n/a (not available).
Volatile organic compounds The station contributes data to the time series trend analysis for annual average volatile organic compounds in the national indicator and regional indicator of the identified region, unless the cell contains n/a (not available).

Annex C

Annex C. Fine particulate matter measurement technological transition

Five (5) types of fine particulate matter (PM2.5) monitors are used to measure the 1-hour concentrations of PM2.5:

  • older technology: Rupprecht & Patashnick tapered element oscillating microbalance (TEOM) monitor
  • current technology: Thermo Scientific TEOM 1400a with the Series 8500C Filter Dynamics Measurement System (FDMS) monitor
  • current technology: Met One BAM-1020 Beta Attenuation Mass monitor
  • current technology: Thermo Scientific 5030 or 5030i SHARP (Synchronized Hybrid Ambient Real-time Particulate) monitor
  • current technology: GRIMM Environmental Dust Monitor model EDM 180 and 365

The Thermo Scientific 1400a, Met One BAM-1020, Thermo SHARP and GRIMM monitors have been approved by the United States Environmental Protection Agency as Class III federal equivalent methods and have been deployed across the National Air Pollution Surveillance network replacing older tapered element oscillating microbalance instruments, which in some circumstances may under report the PM2.5 mass concentrations relative to the National Air Pollution Surveillance PM2.5 Reference Method. Since 2005, the tapered element oscillating microbalance monitors have gradually been replaced by the federal equivalent methods monitors. The federal equivalent methods monitors measure a portion (semi-volatile) of the PM2.5 mass not captured by the older instruments. Because of these measurement differences between the new and the old monitoring equipment, concentrations measured with the new monitors may not be directly comparable with the measurements from years in which older instruments were used.

The following table lists the stations used for the national and regional indicators that are operating with new technologies, along with the type of equipment and the first year when data was provided from a new installation.

Last year Ending year of each time series.
n Number of annual values in the calculation, excluding missing values.
Test Z The absolute value of Z is compared to the standard normal cumulative distribution to define if there is a trend at the selected level α of significance. A positive (negative) value indicates an upward (downward) trend.
Significant The smallest significance level α at which the test shows that the null hypothesis of no trend can be rejected. For the 3 tested significance levels, the following symbols are used:
[A] if trend at α = 0.001 level of significance
[B] if trend at α = 0.01 level of significance
[C] if trend at α = 0.05 level of significance
Q Sen's estimator for the true slope of linear trend, that is, change per unit time period (in this case a year).
Qmin95 The lower limit of the 95% confidence interval of Q (α = 0.05).
Qmax95 The upper limit of the 95% confidence interval of Q (α = 0.05).
