Long-term exposure to PM2.5 species and all-cause mortality among Medicare patients using mixtures analyses.

ABSTRACT:

Background

The relationship between long-term exposure to PM_2.5 and mortality is well-established; however, the role of individual species is less understood.

Objectives

In this study, we assess the overall effect of long-term exposure to PM_2.5 as a mixture of species and identify the most harmful of those species while controlling for the others.

Methods

We looked at changes in mortality among Medicare participants 65 years of age or older from 2000 to 2018 in response to changes in annual levels of 15 PM_2.5 components, namely: organic carbon, elemental carbon, nickel, lead, zinc, sulfate, potassium, vanadium, nitrate, silicon, copper, iron, ammonium, calcium, and bromine. Data on exposure were derived from high-resolution, spatio-tem
