An improved interim toxic emission inventory for the purpose of screening-level regional dispersion and deposition modeling is estimated from a 1990 interim emission inventory of volatile organic compounds (VOCs) for the United States. The VOC emission inventory was derived by updating portions of the 1985 National Acid Precipitation Assessment Program emission inventory. The annual anthropogenic emissions, principal contributing source types, and spatial distributions for four selected toxic VOCs, including acrylonitrile, benzene, perchloroethylene, and trichloroethylene, are presented for the United States. The resulting emission estimates are an improvement over an earlier application of this approach, despite necessary heavy reliance on general and default speciation profiles. Emission totals generally exceed national estimates based on partial or top-down inventory approaches by one to two orders of magnitude.
