The environment ministry has issued a road dust advisory for Burns Lake.
Officials say the poor air quality is the result of high levels of coarse particulate, likely left over from winter sand and gravel operations.
Levels tend to be highest around busy roads and industrial operations.
People with chronic underlying medical conditions should postpone strenuous exercise near busy roads until the advisory is lifted. Exposure is particularly a concern for infants, the elderly and those who have diabetes, and lung or heart disease.
The advisory is expected to remain in effect until there’s some precipitation or dust suppression.
