A study was conducted at the P-I-E Nationwide terminal, Jacksonville, Florida as part of a larger effort to determine whether persons exposed to diesel aerosol as part of their job continued to have an elevated risk of contracting lung cancer after controlling for tobacco smoking and to determine relative exposures to diesel aerosol among the four major presumably exposed job groups: road drivers, local drivers, dock workers, and mechanics. This dock operated 24 hours a day on three shifts. Seven tow motor trucks were located on the dock, six diesel powered, one propane powered. Sampling conducted at the site indicated that most jobs had low level exposures on the order of 6 micrograms/cubic meter (microg/m3). Geometric mean exposures to submicrometer elemental carbon (7440440) ranged from a low of 4.1microg/m3 in mechanics working primarily in the repair shop to 25.4microg/m3 in the dock workers driving diesel powered lift trucks. Only the dock workers had exposures to elemental carbon which were substantially above the concentrations determined from highway area samples. The principal source of the dose workers' exposures was diesel emissions from the fork lift trucks operated on the docks.
