Heavy concentrations of pollutants can be expected and will result in poor air quality tonight, especially in urban areas where emissions of pollutants are greater.
Smog especially affects asthmatic children and people with respiratory ailments or heart disease. It is therefore recommended that these individuals avoid intense physical activity outdoors until the smog warning is lifted.
In Quebec, wood heating is the main source of fine particles that contribute to smog during winter. This activity generates the largest number of these particulates, more than industrial activities and transportation. Please consult your municipality's website to find out if there are any rules governing the use of wood-burning stoves or fireplaces in your community.
