Abstract: A study was conducted to determine whether sufficient ozone is present in the fuselages of high-flying jet aircraft to constitute a potential health hazard for the flight personnel. Over a period of three months, 38 flights were monitored continuously from before takeoff to after landing. The flights ranged from 60 to 325 minutes in duration, and from 9,000 to 39,000 feet in altitude. Combined, they covered the northern and central portions of the continental United States from New York to California, and they included five flights between Hawaii and California. Wide flight-to-flight variations were noted in both the duration and the concentration of the ozone detected. For the remaining 50% of the time, concentrations varied from 0.01 ppm to as high as 0.22 ppm. The maximum continuous exposure has been set at 0.1 ppm, and this concentration was exceeded in the aircraft for approximately 6% of the total flight time. generally, the concentration varied directly with the altitude, but meteorological conditions were also significant.
