Military and civilian researchers will descend upon Grand Forks AFB, N.D., this month to begin a study of the effects of exposure to jet aviation fuel in cold weather. In this first phase of the two-part study, researchers plan to gather data on the level of exposure experienced by airmen during regular work activities. A second phase, set for next year, will focus on the relationship between exposure and health effects, if any.
