Pollutants from Combustion Appliances


Gas stove

We use many combustion appliances in our everyday lives. We burn fuel to cook our food, heat our homes and drive our vehicles. These appliances can produce indoor air pollutants such as carbon monoxide, nitrogen dioxide and wood smoke. Some of these pollutants are harmful but you can protect yourself with a few simple actions.

Health Canada conducts research on various substances, develops guidelines for safe exposure levels and works with government and non-government partners to reduce the associated health risks.

In this section, you can learn more about specific pollutants and how you can manage them to improve the quality of your indoor air.

Did you know?

Gas stoves, fireplaces and furnaces produce carbon monoxide, nitrogen dioxide and small airborne particles called "particulate matter". All of these can increase the level of pollution in your indoor air and affect your health.
