Pollution Probe and the University of Toronto’s Transportation and Air Quality Research Group (TRAQ) present a workshop to showcase findings from researchers at the nexus of transportation and human health on the issue of ultrafine particles (UFPs).

While much of the recent conversation in Canada around transportation emissions has been focused on greenhouse gases (GHG), the potential impacts of air pollution emissions on human health have received comparatively little attention. GHG emissions have been steadily declining in most vehicle classes, however, there are concerns that the introduction of certain fuel-saving technologies, such as gasoline direct injection (GDI) engines and turbochargers, has inadvertently caused a major spike in emissions of ultrafine particles (UFPs), which can cause adverse health impacts.

Why you should attend: The workshop will showcase findings from top researchers in a variety of fields related to transportation and human health. Participants will be provided with opportunities to pose questions and discuss concerns related to UFPs. Further, as an expert in the sector you can contribute to the discussion around potential research needs and identifying effective UFP mitigation strategies. Workshop findings will be summarized in a primer on UFP emissions from transportation and disseminated broadly across Canada.
