Ultrafine particles (UFPs) primarily come from vehicle emissions and industrial activities. Canada’s federal and provincial governments haven’t set concentration limits for UFPs, as they have for larger fine particles known as PM2.5. The study associated long-term exposure to UFPs with a 7.3% increase in the risk of non-accidental death. Respiratory deaths saw the highest increase, at 17.4%, followed by a 9.4% rise in deaths from coronary artery disease.
