Special air quality statement in effect alongside heat warning

Special air quality statement in effect alongside heat warning

Londoners are urged to limit time outdoors on Monday as a special air quality statement is issued on top of an ongoing heat warning.

Smoke from northern Ontario wildfires has moved down into the area, Environment Canada said in a special statement. Poor air quality is expected to continue throughout the rest of the day and possibly into Tuesday.

"As smoke levels increase, health risks increase," said Environment Canada. "Limit time outdoors. Consider reducing or rescheduling outdoor sports, activities and events."

Both Environment Canada and the Middlesex-London Health Unit (MLHU) had urged the public to take steps to stay cool and hydrated during the hot weather. Now there are additional recommendations to deal with the poor air quality, including remaining inside when possible with doors and windows shut, and using a clean, good quality air filter.

"Take precautions to be safe and check in on family, friends, and neighbours, especially those who may be more vulnerable to extreme heat," MLHU said in a statement.

Wildfire smoke can cause mild symptoms including nose and throat irritation, headaches or mild cough. More serious symptoms that may require medical attention include wheezing, chest pains and severe cough.

Those at higher risk of being impacted by wildfire smoke include people aged 65 and older, pregnant people, infants and young children, and those with an existing illness or chronic health condition. It's recommended they wear a well-fitting respirator mask, like an N95, outdoors to reduce exposure to smoke particles.

The heat warning was initially issued Friday for southern Ontario, with daytime highs expected to range from 29 C to 32 C, and with the humidex making it feel like 35 C to 40 C at some points. The warning is expected to remain in effect until Thursday.
