The B.C. Ministry of Environment, in collaboration with Northern Health, cancelled a dust advisory this morning that was issued on Wednesday.
Winds increased slightly and helped flush the fine particulates out of the region, said the agencies. There is a possibility of elevated dust levels today but these levels are expected to remain below the provincial objective for fine particulate air pollution.
Based on data for fine particulates, the agencies had said the high levels were mainly due to road dust.
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.
