Air Quality Index values are divided into four ranges. Each range is further described with a message about possible health and environmental risks. For the complete text of the messages call Manitoba Conservation at 945-7044. Each is updated hourly. Manitoba Conservation publishes annual ambient air quality monitoring reports.
Winnipeg residents are fortunate to enjoy good air quality most of the time.
All residents are encouraged to help maintain our good air quality through increased awareness of the Air Quality Index and by making environmentally friendly choices. Vehicle emissions, for example, are a major cause of air pollution in most cities, including Winnipeg. By using cleaner fuels, properly maintaining our vehicles and choosing to drive our vehicles less often, we will reduce air pollution and help preserve one of Winnipeg's most valuable assets - our fresh, clean air. For further information about air quality and the Air Quality Index system in Winnipeg, please contact Manitoba Conservation at 945-7044. 1 hour and 8-hour running average Carbon monoxide is a colourless, odourless, tasteless gas slightly heavier than air.
