Health Impact Analysis of Wildfire Smoke-PM_2.5 in Canada (2019-2023).

ABSTRACT: Wildfires are a source of air pollution, including PM_2.5. Exposure to PM_2.5 from wildfire smoke is associated with adverse health effects including premature death and respiratory morbidity. Air quality modeling was performed to quantify seasonal wildfire-PM_2.5 exposure across Canada for 2019-2023, and the annual acute and chronic health impacts and economic valuation due to wildfire-PM_2.5 exposure were estimated. Exposure to wildfire-PM_2.5 varied geospatially and temporally. For 2019-2023, the annual premature deaths attributable to wildfire-PM_2.5 ranged from 49 (95% CI: 0-73) to 400 (95% CI: 0-590) due to acute exposure and 660 (95% CI: 340-980) to 5,400 (95% CI: 2,800-7,900) due to chronic exposure, along with numerous no
