Conducted over a 30-year period a study on air pollutants published in the New England Journal of Medicine analysed data on air pollution and mortality in 652 cities across 24 countries and regions. The researchers found that increases in total deaths are linked to exposure to inhalable particles (PM10) and fine particles (PM2.5) emitted from fires or formed through atmospheric chemical transformation. As there's no threshold for the association between particulate matter (PM) and mortality even low levels of air pollution can increase the risk of death said Yuming Guo Professor at Monash University in Australia. The smaller the airborne
