Air pollution is a pervasive consequence of modern societies. Beyond being an environmental hazard, several pollutants such as particulate matter (PM) pose significant health threats.1 Fine PM (<2.5 μm in diameter; PM2.5) is a heterogeneous mixture of compounds (eg, carbon, sulfates, nitrates, and metals) principally derived from the combustion of fossil fuels. Given the billions of people exposed, the adverse effects of PM represent a major global health epidemic.2
