To characterize occupational exposures to carcinogenic chemicals in flight line personnel, polycyclic aromatic
hydrocarbons(PAHs) were determined in JP-4 fueled aircraft emissions both from F-15J and C-130H. The gasand
aerosol-phase PAHs were determined by gas chromatography coupled to mass spectrometry and by high
performance liquid chromatography with fluorescence detection, respectively. The results showed differences in
aerosol PAHs between both aircrafts. C-130H produced higher concentrations of the aerosol PAHs, including 3 or
4 ring-PAHs, fluorene, phenanthrene, anthracene, fluoranthene and pyrene. In contrast, the F-15J emissions
included carcinogenic 5 or 6 aromatic ring- PAHs, benzo(b)fluoranthene, benzo(k)fluoranthene, dibenzo(a,h)
anthracene, benzo(ghi)perylene and indeno(1,2,3-cd)pyrene. In the gas-phase, both aircraft emissions mainly
included about 0.1ppm of naphthalene, which was below the permissible exposure limits given by Occupational
Safety and Health Administration(OSHA).
