Monitoring Reports on Canadian Ambient Air Quality Standards
2015 and 2016 reports
The annual reports on Canadian ambient air quality standards (CAAQS) describe the concentrations of ozone and fine particulate matter measured in the ambient air in Québec from 2012 to 2015.
Data from 46 air quality monitoring stations were used to produce the report. The stations are located in Québec’s three air management zones (AMZs): South, North and East.
From 2013 to 2015, 95% of the stations achieved the annual CAAQS in terms of fine particulate matter, compared to 90% for the 2012-2014 period and 80% for 2011-2013. The stations are located in densely populated urban environments. All the stations achieved the daily CAAQS, compared to 98% of the stations for 2012-2014 and 93% for 2011-2013.
The ozone values at all the stations achieved the CAAQS, as was the case for 2012-2014.
The South AMZ is experiencing the most impacts. As home to almost 90% of Québec’s population, it has the highest density of air emission sources. In addition, it is affected by emission sources situated outside Québec. Furthermore, the only CAAQS value exceedances observed are from air quality stations in this AMZ. The North and East AMZs, which each have only one reporting station, show better air quality than the South AMZ.
