One way to help decrease smog is by carpooling or taking public transit
Environment Canada has issued another round of smog advisory alerts for portions of Ontario.
Yesterday, southern Ontario, cottage country and parts of the Nickel Belt were put on alert as the air quality continued to deteriorate.
"We've been seeing a stagnant air mass, mixed with calm winds," says Gina Ressler, a meteorologist at The Weather Network. "This, combined with high pressure, keeps pollutants near the surface."
Sunday's forecast is calling for more of the same. Light winds and a hot and sunny forecast will create a stagnant weather pattern -- and this could cause the air quality index to exceed the "poor" threshold rating.
Spare the air day
On days of elevated pollution, the public is encouraged to reduce smog by walking, taking public transit and carpooling. The initiative is called "Spare the Air" days and it is supported by the Government of Ontario.
Smog advisories are issued when the forecast calls for poor air quality within a consecutive, 24-hour period due to ground-level ozone and/or particulate matter.
During the smog episode, individuals may experience eye irritation and it's common for people with respiratory problem to experience difficulty breathing.
The latest round of advisories are expected to remain in place through to Monday.
Outdoor activities should be kept at a moderate level throughout the long weekend
