US coal power plants killed at least 460,000 people in past 20 years – report

Pollution caused twice as many premature deaths as previously thought, with updated understanding of dangers of PM2.5

Coal-fired power plants killed at least 460,000 Americans during the past two decades, causing twice as many premature deaths as previously thought, new research has found.

Cars, factories, fire smoke and electricity plants emit tiny toxic air pollutants known as fine particulate matter or PM2.5, which elevate the risk of an array of life-shortening medical conditions including asthma, heart disease, low birth weight and some cancers.
