In 2021, recognizing the health burden of exposure to fine particulate matter (PM2.5), the World Health Organization cut its guideline for annual average exposure in half. Now 86% of Canadians live in areas that exceed the new WHO guideline. Exposure to air pollution is estimated to cause 7 million deaths every year, and exposure to PM2.5 in particular has been linked with premature death in people with heart or lung disease, nonfatal heart attacks, aggravated asthma, decreased lung function and coughing or difficulty breathing.

Join us for a webinar to better understand what PM2.5 is, where it comes from, how it’s measured and its effect on health with Dr. Jeff Brook, Assistant Professor at the Dalla Lana School of Public Health, University of Toronto, and Scientific Director of CANUE, and Aaron van Donkelaar, Research Associate with the Atmospheric Composition Analysis Group at Washington University in St. Louis.
