Long term exposure to airborne fine particulate matter (PM2.5) and ozone increases the risk of premature death even at levels below current air quality standards, a US study of 60 million people suggests.1
Researchers writing in the New England Journal of Medicine said that lowering PM2.5 by just 1 microgram per cubic metre (μg/m3) throughout the United States could save 12 000 lives every year. Similarly, if the level of ozone could be lowered by just one part per billion (ppb) nationwide, another 1900 lives a year could be saved.
