Research summary
Wildfire smoke contains small airborne particles (particulate matter) and organic vapours known as volatile organic compounds. Because of this complex composition and the lack of data on the fuels driving Canadian wildfires, scientists cannot fully predict the environmental impacts of these fires. As Canada Research Chair in Atmospheric Chemistry, Dr. Ran Zhao aims to close this critical knowledge gap.
He and his research team are measuring the emission factors of key air pollutants from Canadian wildfires and developing advanced methods to identify and quantify complex chemical compounds in smoke. Through collaborative, multi-disciplinary research that focuses on vulnerable populations and indoor air quality in classrooms, they are studying the negative health impacts of wildfire smoke. Their findings will enhance our understanding of the environmental and health impacts of wildfire emissions in Canada, supporting better public health and policy responses.
