Inhalation Exposure to let Fuel (JPS) Among U.S. Ai r Forcc Personnel

As jet fuel is a common occupational exposure among military and civilian populations, this study was conducted to characterize jet fuel (JP8) exposure among active duty US Air Force Personnel. Personnel (n=24) were divided a priori into high, moderate, and low exposurc groups. Questionnaires and personal air samples (breathing zone) were collected from each worker ovcr 3 consecutive days (72 worker-days) and analYLed for total hydrocarbons (THC), benzene, toluence, ethylbenzene. xylenes, and napthalene. Air Samples wcre collected from inside the fuel tank and analyzed for the same analytes. Linear mixed-effects models were used to evaluate the exposure data. Our results show that the correlation ofTHC (a measure of overall JP8
inhalation exposure) with all other analytes was moderate to strong in the a priori high and moderate exposure groups combined. Inhalation exposure to all analytes varied significantly by self-reported JP8 exposure (THC levels higher among workersreporting JP8 exposure), a priori exposure group (THC levels in high group > moderate group > low group), and more specific job
task groupings.
