To characterize occupational exposure to harmful compounds in JP-4 fueled aircraft emissions, volatile organic compounds (VOCs) were determined in the emissions from F-4, T-4, C-130 and F-15. VOCs in the emissions were collected to active charcoal tube and analyzed by gas chromatography. There were 5 aromatic hydrocarbons (benzene, toluene, ethylbenzene, m,p-xylene and o-xylene) and 10 straight chain alkanes (n-hexane, n-heptane, n-octane, n-nonane, n-decane, n-undecane, n-dodecane, n-tridecane, n-tetradecane and n-pentadecane) in F-4 and F-15 exhaust. In T-4 exhaust, except for n-hexane, detected components is much the same in F-4 and F-15. On the other hand, C-130 exhaust contain 2 aromatic hydrocarbons (benzene and toluene) and 4 straight chain alkanes (n-hexane, n-heptane, n-octane and n-nonane). The total VOCs amounts in F-4, T-4, C-130 and F-15 exhaust were 899ppb, 1269ppb, 77ppb and 26ppb, respectively. In conclusion, we revealed components and concentrations of VOCs in each JP-4 fueled aircraft emissions.
