Description:
The paper presents the first known values for emissions of polychlorinated dibenzodioxins and dibenzofurans (PCDDs/Fs) from combustion of agricultural field biomass. Wheat and rice straw stubble collected from two western U.S. states were tested in a field burn simulation to determine emission factors. The resulting emission factor was approximately 0.5 ng TEQ/kg(burned) for both sources. When coupled with published agricultural data on crop residue burning, about 1 g TEQ/year can be expected from wheat and rice straw residue burning, making this an apparently minor source of PCDDs/Fs in the United States.
