Environment Canada has issued a special air quality warning for Montreal. The city is experiencing poor air quality and reduced visibilities due to smoke from wildfires in the region.
According to IQAir, air quality in the city is currently “unhealthy for sensitive groups.” Montreal is currently among the Top 10 most polluted cities in the world.
Environment Canada suggests limiting time outdoors and reducing or rescheduling outdoor activities and events. When indoors, keep windows and doors closed as much as possible.
Those most likely to suffer health effects from poor air quality are people over 65, pregnant women, young children, people with chronic health conditions and those who work outdoors, who should avoid strenuous activity and seek medical attention if they experience symptoms.
Mild symptoms that could affect anyone under these conditions include nose, eye and throat irritation as well as headaches, while more severe symptoms include wheezing, chest pains or a severe cough.
“As smoke levels increase, health risks increase. Protect your indoor air from wildfire smoke. Actions can include using the highest quality air filter that your ventilation system can handle and/or a certified portable air cleaner that can filter fine particles.”
Cette fin de semaine, des concentrations élevées de particules fines liées aux feux de forêt pourraient entraîner une mauvaise qualité de l’air dans plusieurs régions du Québec, dont Montréal. https://t.co/ZNZrtm0yxX
