The first air quality advisory of the year was cancelled this morning just less than 24 hours after it had been issued.
The advisory had been issued Tuesday for high levels of fine particulate pollution that accumulated in the city as an upper high-pressure ridge moving over the region.
Based on the air quality data, the high levels had been mainly due to a combination of wood smoke, emissions from industry and road dust.
B.C. Ministry of Environment officials had not expected the advisory to last long as winds were expected to increase as the ridge moved through the area.
Prince George normally experience several air quality advisories each year.
The city perennially ranks among communities in British Columbia with the worst levels of fine particulate air pollution.
In 2010, average yearly fine particulate levels increased over the previous year because of forest fires in August. Removing the six days of high levels due to the smoke would decrease the averages slightly from those in 2009, according to B.C. Environment preliminary data.
