An estimated 4 billion people live with hazardous levels of air contamination, most of them in Asia. Current efforts to reduce global air pollution are insufficient to combat atmospheric pollution.

To meet this challenge, XPRIZE is designing a prize competition that will achieve breakthroughs either in technology or innovation that eliminate or a dramatically reduce the amount of air pollution related to fine particulate matter -- and makes these innovations accessible globally.

PM and health effects

Our research on PM and health outcomes has turned up two findings: 1) On a mass basis, the health effects of PM 0.1 and PM 2.5 are generally the same, or rather that 0.1 is not significantly worse on health than 2.5 & 2) the research on ultrafine PM 0.1 is lacking and its impact on health outcomes isn't well understood.

Question: Is there a significant difference in health effects between PM 2.5 and PM 0.1 on a mass basis? Does the composition of particulate matter affect health outcomes in different ways? Is this an area that is generally understood and supported by evidence?
