National Air Pollution Surveillance (NAPS) Network in CanadaEntry ID: CANEMRCCRSAIRPOLLUTION
Abstract: The National Air Pollution Surveillance (NAPS) Network was established in 1969 as a joint program of the federal and provincial governments to monitor and assess the quality of the ambient air in Canadian urban centres.
Air quality data for sulphur dioxide (SO2), carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3) and total suspended particulates (TSP) are measured at over 152 stations in 55 ... cities in the ten provinces and two territories. Various statistics derived from the measurements and comparisons with the National Air Quality Objectives prescribed under the Canadian Environmental Protection Act are published in annual data reports.
In addition to the criteria pollutants, the Division, with the assistance from provincial and municipal NAPS network cooperating agencies, carries out a number of other monitoring activities to support priority national air issues.
For Canada's national Smog (Ground-Level Ozone) Management Program, data for nitric oxide, nitrogen oxides and volatile organic compounds (VOCs) are being collected. The NAPS database has been expanded to include ozone observations from Canadian and U.S. rural monitoring locations in order to allow analysis of regional ozone episodes.
Measurements of PM10 (suspended particles with aerodynamic diameters less than 10 micro meters) and PM2.5 have been made at Canadian sites since 1984. Sample filters are analyzed for 50 elements (including toxic metals such as arsenic, lead and mercury) 14 inorganic and organic anions and 11 inorganic cations.
Since 1988, the Centre has been developing and applying improved techniques for measuring potentially toxic air contaminants. Measurements of VOC (aromatics, aldehydes and ketones) and semi-volatile organic compounds (PAHs, dioxins and furans) are now carried out at 40 urban and rural locations in Canada. The data have formed the principal ambient air exposure data base for 14 Canadian Environmental Protection Act (CEPA) Priority Substances List (PSL) assessments.
A number of reports which provide results from the toxic air monitoring programs are available upon request.Air quality data gathered by the NAPS Network provide the basis for evaluating air pollution control strategies, identifying urban air quality trends and for warning of emerging air pollution issues. The recognition in recent years of the importance of long range transport of air pollution (both national and international) underlines the usefulness of a nationwide network of air monitoring stations.
