OEH Seminar: Building an evidence base for better subway air quality: The Subway Air Quality Initiative

Over the past 20 years, the body of research on subway air quality has grown dramatically. This work revealed high particulate matter (PM) levels sourced from brake and steel dust. Concentrated in the confined spaces of below-grade transit, PM2.5 levels can constitute a significant proportion of daily exposure for the substantial proportion of Canadians who use this method of transit. The Subway Air Quality Initiative (SAQI) aims to investigate the sources, trends, and mitigative strategies of subway PM to inform evidence-based air quality policy. Similar work is ongoing internationally as poor subway air quality is an emerging issue for several major cities around the world. 

Présentateur(s): Keith Van Ryswyk

Keith Van Ryswyk joined Health Canada in 2006 in the Air Health Science Division. In 2010, he began research assessing air pollution exposures in Canadian urban transit environments. This work lead to a focus on Canadian subway environments. In 2017, he joined the Southern Ontario Center for Atmospheric Aerosol Research (SOCAAR) as a PhD student with Dr. Greg Evans and began the Subway Air Quality Initiative (SAQI). This study aims to build a foundation of evidence upon which subway air quality policy can be designed.
