(NIOSH 2002-2004) The aim of this project was to investigate farm workers’ exposure to agricultural burning smoke and the resulting airborne pollutants and to assess the potential health hazards. Washington State University was our principal partner on the project. The results showed acute exposure at levels far higher than the EPA’s National Ambient Air Quality Standard and the occupational standards for respiratory dust. These preliminary results contribute to a larger study conducted in the same agricultural community on exposure and health effects in a research partnership between the UW Department of Environmental and Occupational Health Sciences and Washington State University. The long-term impact of this and subsequent studies could effect workplace practices and government policy.
