Saskatoon and Regina are both under special air quality statements due to an increase in air pollution levels.
Environment Canada issued the statement Monday morning.
“The air quality values when the warnings or statements go out (are) usually seven or higher and that’s the range that we’re in, normally it sits around two or three,” explained Environment Canada meteorologist Terri Lang.
She said warm air has set in high in the atmosphere over the province which creates a strong temperature inversion.
“That’s sort of like a cap over the atmosphere and the lower layers,” she said, noting this traps pollutants from cars and industry in the lower level which decreases the air quality.
Rural areas aren’t as affected by the air quality issue because the concentration of traffic is so low.
Those most at risk from this are children, the elderly and people with lung diseases such as asthma.
A westerly wind is expected to go through the province in the coming days to push out the warm air. Air quality is expected to begin to improve on Tuesday.
