Millions of Canadians are at higher risk of dying, even at low levels of exposure to fine particulate matter air pollution (PM2.5), levels that are below U.S. and other ambient air quality regulations, according to a recent comprehensive analysis by the Health Effects Institute (HEI). Lowering regulatory limits might result in additional health advantages because long-term outdoor PM2.5 exposures at levels as low as 2.5 micrograms per cubic meter were linked to an increased risk of death. Michael Brauer and his colleagues at The University … Continue reading Even Low Air Pollution Can Be Fatal For Health, New Study
