Research summary
According to the World Health Organization, particulate matter in polluted air is responsible for approximately seven million deaths a year around the world. Particulate matter consists of small solid or liquid particles produced from burning materials, road dust, construction and agriculture. Air quality is affected by the types and amounts of these released particles as well as by wind, precipitation and temperature variables.
Dr. Sarah Styler, Canada Research Chair in Atmospheric Chemistry, aims to improve our understanding of the air quality, climate and health challenges posed by two classes of urban particulate pollution: non-exhaust emissions (pollution from brake and tire wear) and wildfire smoke. Styler and her research team are also developing new tools to study particulate reactivity, and applying atmospheric chemistry principles to understand and prevent the surface-mediated degradation of cultural heritage objects.
