Smog WarningIssued at 06:31 Wednesday 20 January 2021
High concentrations of pollutants trigger a poor air quality this morning, especially in locales where the emissions of pollutants are more significant.
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.
