Study of air quality in the U.S. shows income disparities still exist

A small team with members from the University of Virginia, Stanford University, and the U.S. Census Bureau has found that despite laws enacted to reduce unequal distribution of emissions of airborne particulate matter smaller than 2.5 µm in diameter (PM2.5) in the U.S., disparities remain. In their paper published in the journal Science, the group analyzed data over the past several decades to learn more about air quality in the U.S. Lala Ma, with the University of Kentucky, has published a Perspective piece on the work done by the team in the same journal issue.
