Health benefits that have resulted from reductions in fine particulate air pollution aren’t distributed equally among populations in the U.S., a new Yale-led study finds. Racial and ethnic minorities — and Black people in particular — still experience disproportionately high rates of cardiovascular disease-related deaths caused by exposure to fine particulate matter, according to the research.
The findings were published Aug. 31 in Nature Human Behavior.
Fine particulate matter, also known as PM2.5, consists of particles or droplets smaller than 2.5 micrometers in diameter, or 30 times smaller than the width of a human hair. While some PM2.5 in the environment comes from natural sources, such as wildfires, the majority of particulate matter pollution in the U.S. is the result
