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 2014-2016 is the third annual report on the CAAQS for Alberta. This report assesses levels of fine particulate matter and ground-level ozone measured in the years 2014, 2015, and 2016 and determines air quality management levels for each air zone for the 2014-2016 assessment period.
The CAAQS were achieved in all six air zones for both fine particulate matter and ozone. With the exception of the Peace air zone, management levels improved or stayed the same management level compared to the previous assessment. The 2014-2016 assessment period is the first period that the Peace air zone is at the orange (Actions for Preventing CAAQS Exceedances) management level for fine particulate matter. In all previous reporting periods, the Peace air zone was at the yellow (Actions for Preventing Air Quality Deterioration) management level.
