OSTI ID:7028353
An in-depth survey was conducted at Roadway Express, Inc., Toledo, Ohio to determine relative exposures to diesel aerosols among the four major presumably exposed job groups of road drivers, local drivers, dock workers, and mechanics. Element carbon sampling results at the Roadway terminal in Toledo, Ohio, during cold weather indicated low level exposures only slightly above geometric mean ambient residential and highway background concentrations in road drivers and local drivers. Exposures were significantly above background highway concentrations in dock workers and in mechanics, with exposures of 29 and 58 micrograms/cubic meter (microg/cu m), respectively. The highest levels of exposure were to mechanics working in the shop. Exposure to nitrogen oxides and respirable particulates were far below recommended limits. The major source of exposures in dock workers appeared to be the operation of diesel powered fork lift trucks on the dock. The principal source in mechanics was the entry and egress of diesel tractors to and from the shop area, but the more enclosed environment in which they were working exacerbated concentrations of diesel aerosols.
