Air pollution—specifically PM 2.5 , ozone and NO 2 —could be to blame for up to 33 million emergency asthma attack visits to hospital a year, according to a new open-access study published in the journal Environmental Health Perspectives. 37% and 73% of ozone and PM 2.5 Anthropogenic emissions were responsible for ?37%

Both aircraft will measure ozone and a mixture of soot and PM. Other instruments on the P-3B will measure pollutants that lead to the formation of ozone such as nitrogen dioxide and formaldehyde. Overall, the World Health Organization estimates that air pollution causes some 2 million premature deaths globally per year.
