SPECIAL AIR QUALITY STATEMENT IN PLACE

“Multi layer smoky mess” across Western Canada

Jul 19, 2021 | 7:46 AM

EDMONTON, AB. — Heat warnings have ended, but they’ve been replaced by special air quality statements covering much of western Canada.

Smoke from western wildfires have created what Justin Shelley at Environment Canada is calling a “multi-layered smoky mess”.

While smoke issues in Alberta last week were largely due to the B-C fires, a wind change has meant most of the smoke in cities like Edmonton and Calgary is now coming from other wildfires in northern Saskatchewan.

People with lung issues are more likely to experience problems, but the smoke can affect everyone with symptoms including increased coughing, throat irritation and shortness of breath.

Wildfire smoke is causing poor air quality and reducing visibility at times.

Very high AQHI values are being reported through much of Alberta and are expected to remain high through mid week in central and northern regions.

In Southern Alberta AQHI values are forecast to moderate with southeasterly winds today.

Air quality can fluctuate over short distances and can vary considerably hour by hour.

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.

If you or those in your care are exposed to wildfire smoke, consider taking extra precautions to reduce your exposure. Wildfire smoke is a constantly-changing mixture of particles and gasses which includes many chemicals that can harm your health.
