Human Health Assessment for Diesel Exhaust

This risk assessment provides a comprehensive review and analysis of the potential adverse health effects associated with diesel fuel use in Canada. The report focuses on diesel exhaust (DE) emissions from on-road and off-road vehicles (excluding rail and marine applications) and targets impacts resulting from general population exposures. The assessment includes a review of diesel fuels, engines and emissions, a review of exposure to DE, an evaluation of the health effects associated with DE exposure, as well as a quantitative analysis of the population health impacts associated with the contribution of DE to criteria air contaminant concentrations in Canada. This report does not address the health risks of diesel fuel itself, which is under review as part of the Chemicals Management Plan of the Government of Canada and will be reported elsewhere.
