January 41 3648. Previous research in the railroad industry has shown an association between lung cancer and exposure to diesel emissions is associated with lung cancer within the range of 2050 has been observed in more than studies of workers exposed to diesel exhaust. As part of this study, an extensive exposure assessment was started in to determine current exposure levels in the cohort, as well as factors that have influenced historical exposure levels.

Previous research in the railroad industry has shown an association between lung cancer and exposure to diesel emissions is associated with lung cancer within the trucking industry. To help identify potential upwind sources, wind direction weighted averages and speed measurements were used to construct wind roses, which were superimposed on overhead photos of the terminal and examined for upwind source activity. This proximity to pollution sources, coupled with meteorological conditions and wind patterns, affect occupational exposures to particles at these work locations.

This proximity to pollution sources, coupled with meteorological conditions and wind patterns, affect occupational exposures to particles at these work locations. To help identify potential upwind sources, wind direction weighted averages and speed measurements were used to construct wind roses, which were superimposed on overhead photos of the terminal and examined for upwind source activity. Our results provide evidence that nearby upwind pollution sources significantly elevated background concentrations at only few of the locations sampled, while the majority provided little to no evidence of significant upwind source effect.
