Short-Term Exposure to Fine Particulate Matter and Ozone: Source Impacts and Attributable Mortalities.

ABSTRACT: Short-term exposure to particles with aerodynamic diameters less than 2.5 μm (PM_2.5) and ozone (O₃) are important risk factors for human health. Despite the awareness of reducing attributable health burden, region-specific and source-specific strategies remain less explored due to the gap between precursor emissions and health effects. In this study, we isolate the health burden of individual sector sources of PM_2.5 and O₃ precursors, nitrogen oxides (NO_x) and volatile organic compounds (VOCs), across the globe. Specifically, we estimate mortalities attributable to short-term exposure using machine-learning-based daily exposure estimates and quantify sectoral impacts using chemical transport model simulations. Globally, short-te
