Particulate pollution from coal associated with double the risk of mortality than PM2.5 from other sources

Exposure to fine particulate air pollutants from coal-fired power plants (coal PM2.5) is associated with a risk of mortality more than double that of exposure to PM2.5 from other sources, according to a new study. Examining Medicare and emissions data in the U.S. from 1999 to 2020, the researchers also found that 460,000 deaths were attributable to coal PM2.5 during the study period -- most of them occurring between 1999 and 2007, when coal PM2.5 levels were highest.
