Levels of fine particulate matter (PM2.5) have improved over the past 15 years due to management actions, but in recent years have been significantly impacted by hot weather and more active wildfire seasons. Odour levels in the community (indicated by total reduced sulphur -TRS) have improved greatly since the 1960's, but have shown a slight increase in recent years. While TRS is considered a nuisance pollutant at these levels, it has an offensive odour that is annoying to residents and impacts community image.
This short report provides an update on improving particulate matter levels in the airshed since the 1990's. The key to improvement has been more effective management at the source, in particular, the phase-out of all beehive burners, increased removal of fine particulate matter from multiple industrial partners, decreased open burning, use of coarser traction material on streets in winter and improved street cleaning practices.
In 2011-2012, the Ministry of Environment worked in collaboration with city residents to collect ambient air samples within an odour-affected neighborhood, and analyzed the samples for 194 volatile organic compounds (VOCs). The report from this Sampling Program provides a summary of VOCs that were measured in the outdoor air and provides recommendations for next steps.
Other Studies for the Prince George Airshed
The Ministry of Environment in collaboration with Prince George residents conducts special studies of some pollutants (e.g. formaldehyde, volatile organic compounds), in addition to their routine monitoring program for the airshed. The results of these additional monitoring studies can be found here.
These short Briefing Notes provide a snapshot of particulate matter (PM) in the Prince George Airshed.
Prince George Air Quality Improvement Briefing Notes
Each member of PGAIR has been requested to provide an annual update on air quality improvement activities, and particularly implementation activities related to the PGAIR Phase III Plan. Collectively these Briefing Notes help identify and share progress towards achieving community air quality goals for PM2.5 reduction: By 2016, A 40% reduction in PM2.5 from all significant sources; A daily average not to exceed 25 micrograms per cubic meter of air; and An annual average of 5 micrograms per cubic meter of air.
