Air Quality Advisory Continues
Friday, October 25, 2013 @ 9:41 AM
Prince George, B.C. – The Air Quality Advisory for Prince George continues today.
Air Pollution Meteorologist Dennis Fudge even though levels of fine particulate are below the 24 hour averaged targets, the same cannot be said about coarse particulate.
The provincial air quality objective for fine particles (PM2.5) is 25 micrograms per cubic metre, averaged over 24 hours. The 24 hour PM2.5 rolling average was 22 µg/m3 at the Plaza 400 downtown site and 16 µg/m3 at College Heights at 8 this morning
The provincial air quality objective for coarse particles (PM10) is 50 micrograms per cubic metre, averaged over 24 hours. The 24 hour PM10 rolling average was 57 µg/m3 at the Plaza 400 downtown, 28 µg/m3 at College Heights and 33 µg/m3 at BCR at 8 this morning.
Based on the air quality data, the high levels are mainly due to Industry sources and some contribution due to open burning.
The high pressure ridge sitting over the region will slowly weaken over the next 24 hours. This ridge resulted in light winds and foggy conditions which caused pollutants to become trapped in the bowl area of Prince George.
Higher particulate levels, as well as odour, can be expected late this morning and this afternoon once the fog burns off. Air quality is expected to be better at higher elevations.
This Air Quality Advisory is expected to be in effect until late this afternoon, with an update to be provided today at 4:00 p.m. or earlier if conditions improve.
