Special air quality statement in place as wildfire smoke moves into London region

A special air quality statement is in effect as wildfire smoke moves into the London region, and experts are advising people to remain indoors when possible.

The Air Quality Health Index spiked to a 10 in the early morning on Friday. Index readings of 7 through 10 indicate a high risk.

The numbers were expected to decrease across the day but there are still potential health risk, particularly for the elderly, children and those with chronic health conditions, according to Kelly Hobelman from Environment Canada.

"There definitely are risks, especially to those who are outside for longer durations," she said.

The smoke is the result of raging wildfires continuing to burn across the prairies and northern Ontario, where many remain under evacuation orders.

Effects of smoke can vary. Mild symptoms can include eye, nose and throat irritation, but more serious, less common effects could include wheezing, chest pains or cough.

The smoke can affect indoor areas, as well, so it is important to take precautions, said Hobelman. She recommends keeping doors and windows closed as much as possible, and using air cleaners with HEPA filters to remove smoke particles.

Environment Canada is expecting conditions to improve later in the day as wind pushes the smoke further south, but there is a risk of the smoke returning, Hobelman said.

"Some of the models are suggesting that there could be a bit of smoke returning for Sunday, but it's a bit far out to say for sure," she said. "So just keep an eye out on your air quality forecast."
