The Canadian Ambient Air Quality Standards (CAAQS) are national ambient air quality standards intended to protect human health and the environment. The CAAQS focus on assessing fine particulate matter and ground-level ozone as there are significant human health and environmental effects associated with these parameters. The Environmental Monitoring and Science Division (EMSD) produces annual reports on the CAAQS, which are one of the measures to provide Albertans with an assessment of their air quality.
The Alberta: Air Zones Report 2012-2014, 2013-2015 is the second annual report on the CAAQS for Alberta. This report assesses levels of fine particulate matter and ground-level ozone measured in the years 2012, 2013, 2014, and 2015 and determines air quality management levels for each air zone for the 2012-2014 and 2013-2015 assessment periods.
The CAAQS were achieved in all six air zones for both assessment periods for both fine particulate matter and ozone. With the exception of the Red Deer air zone, management levels did not change between the previous assessment period (2011-2013) and the 2012-2014 and 2013-2015 assessment periods. Air quality in the Red Deer air zone changed from the red management level (Actions for Achieving CAAQS) for 2011-2013 to the orange management level (Actions for Preventing CAAQS Exceedances) for 2012-2014 and 2013-2015.
