Ozone levels in airplane cabins, and factors that influence them,werestudiedonnorthernhemispherecommercialpassenger flights on domestic U.S., transatlantic, and transpacific routes. Real-time data from 76 flights were collected in 2006–2007 with a battery-powered UV photometric monitor. Sample mean ozone level, peak-hour ozone level, and flight-integrated ozone exposures were highly variable across domestic segments (N ) 68), with ranges of
