dc.description.abstractExposure to fine particulate matter (PM2.5) is known to cause adverse health outcomes. Most of the evidence has been derived from developed countries, with lower pollution levels and different demographics and comorbidities from the rest of the world. Here we leverage new satellite-based measurements of PM2.5, combined with comprehensive public records in Chile, to study the effect of PM2.5 pollution on elderly mortality. We find that a 10 mu g/m3 monthly increase in PM2.5 exposure is associated with a 1.7% increase (95% C.I.: 1.1-2.4%) in all-cause mortality for individuals aged 75+. Satellite-based measurements allow us to comprehensively investigate heterogeneous effects. We find remarkably similar effect sizes across baseline exposure, rural and urban areas, income, and over time, demonstrating consistency in the evidence on mortality effects of PM2.5 exposure. The most notable source of heterogeneity is geographical, with effects closer to 5% in the center-south and in the metropolitan area.
dc.description.abstractFor Chilean people aged 75 and over, a monthly increase in the levels of fine particulate matter, a form of air pollution, are consistently associated with higher all-cause mortality, based on an analysis of satellite PM2.5 data and health records.
