Air Quality Monitoring

It was determined early on in the planning process that, in order to develop appropriate recommendations to improve air quality in Quesnel, we first needed a thorough, scientific understanding of what was causing the problem. One step in furthering our understanding was to monitor the air for air pollution and then compare the results to provincial and federal air quality criteria. In Quesnel, the Ministry of Environment, in partnership with the Quesnel Air Quality Roundtable, monitors the community air for ground-level Ozone (O3), Nitrogen Oxides (NOx), Total Reduced Sulphur (TRS), Carbon Monoxide (CO), Sulphur Dioxide (SO2), and fine particulates less than 10 microns in diameter and 2.5 microns in diameter – termed PM10 and PM2.5 respectively.

Meteorology measurements (wind speed, wind direction, temperature, and relative humidity) are made at two locations in Quesnel; fine particulates are measured at three locations; TRS at two locations and NOX, O3, SO2, and CO are measured only in the downtown area.
