Disparities in PM2.5 air pollution in the United States
Jonathan Colmer, Ian Hardman, Jay Shimshack, and John Voorheis
Our paper, published in Science, shows that while there have been substantial reductions in PM2.5 over the last few decades, meaningful disparities persist. The most polluted areas in 1981 are still the most polluted. The disadvantaged communities that were exposed to more pollution in 1981 are still more exposed to more pollution today.
