Comparison of Operational Jet Fuel and Noise Exposures: Fuel Exposure Results
Abstract
The study purpose was to examine effects on hearing in flight line personnel with combined exposure to jet fuel and noise. We analyzed fifteen volatile organic compounds (VOCs) jet fuel components in personal air samples, blood and urine at Japan Air Self Defense Force (JASDF) and United States Air Force (USAF) air bases. There were 168 subjects who voluntarily joined this study at 5 JASDF air bases (ABs) and 2 USAF ABs in Japan. Subjects were divided into eight groups: CJ, Non-exposed control subjects in JASDF; CK, Non-exposed control subjects at Kadena; CM, Non-exposed control subjects at Misawa; T-4, JetA1 exposed T-4 flight line crews at Matsushima and Hamamatsu; F-2, JetA1 exposed F-2 flight line crews at Matsushima; F-4, JP-4 exposed F-4 flight line crews at Hyakuri; F-15, JP-8 exposed F-15 flight line crews at Kadena; F-16, JP-8 exposed F-16 flight line crews at Misawa. Only total VOCs of all samples of F-4 were higher than those of the control group for the same AB. Benzene was found at high frequencies and concentrations in all samples for the F-4. These results are characteristic of JP-4 exposure, which due to higher volatility, has a different composition than JP-8 and JetA1.
