Short-term exposure to fine particulate pollution and elderly mortality in Chile

P. Busch, P. Rocha, et al.

This study conducted by Pablo Busch, Paulo Rocha, Kyung Jin Lee, Luis Abdón Cifuentes, and Xiao Hui Tai unveils a startling link between PM2.5 pollution and increased mortality among the elderly in Chile. A mere increase of 10 µg/m³ in air pollution can lead to a 1.7% rise in all-cause mortality for those aged 75 and above, revealing alarming patterns across various demographics and locations.

Abstract

This study investigates the short-term impact of PM2.5 pollution on elderly mortality in Chile using satellite-based PM2.5 measurements and comprehensive public records. A 10 µg/m³ monthly increase in PM2.5 is associated with a 1.7% increase in all-cause mortality for individuals aged 75+. The effect is consistent across various demographics and geographical areas, with the most significant impact observed in the center-south and metropolitan areas of Chile.
