Nearly all of Alberta, aside from the southwestern corner and Lac La Biche-Cold Lake area, was under an air quality warning from Environment Canada on Thurs. May 30.
All of east-central Alberta has been included in this warning as conditions waver throughout the day.
Smoke from wildfires in northern Alberta is causing poor air quality and reducing visibility in some areas.
By 3 p.m., the area of smoke extended from northwestern Alberta through Whitecourt then towards Hanna and was slumping southwards.
In central and southern parts of the province, smoke is expected to move back north by Friday morning as the flow shifts to southeasterly.
Environment Canada noted that individuals may experience symptoms such as increased coughing, throat irritation, headaches or shortness of breath.
Children, seniors, and those with cardiovascular or lung disease, such as asthma, are especially at risk.
People with lung diseases, such as asthma and COPD, can be particularly sensitive to air pollution.
They will generally experience more serious health effects at lower levels.
Pollution can aggravate their diseases, leading to increased medication use, doctor and emergency room visits, and hospital visits.
“Stay inside if you have breathing difficulties. Find an indoor place that’s cool and ventilated. Using an air conditioner that cools and filters air may help. If you open the windows you may let in more polluted air. If your home isn’t air-conditioned, consider going to a public place (library, shopping mall, recreation centre) that is air-conditioned,” stated the advisory.
