Air Quality Monitoring Programs
SESAA began data collection with a passive monitoring program in June of 2006. The program will monitor nitrogen dioxide, sulphur dioxide, hydrogen sulphide, ground level ozone, and fine particulate levels throughout southeast Saskatchewan. A continuous monitoring program was added in the spring of 2010. Continuous monitoring equipment provides nearly instantaneous measurements of ambient concentrations for several pollutants. Continuous sampling involves drawing air through a commercial analyzer calibrated to produce an output that is proportional to the ambient pollutant concentration.
What We Monitor
Ambient air is a complex mix of substances in the gaseous, liquid, and particulate (solid) phases. These substances may occur naturally, originate from anthropogenic (human-related) activities, or result from interactions between substances released from one or both of these sources.
SESAA currently measures nitrogen dioxide, sulphur dioxide, hydrogen sulphide, ground level ozone and fine particulate levels in the ambient air.
