Abstract A preliminary assessment of the potential environmental impact of automotive sulfuric acid (or sulfate) aerosol has been made by analyzing the aerosol dynamics. This analysis leads to the prediction of ambient automotive sulfuric acid aerosol concentrations over and around a large, ten-lane highway (48 m. x 20 km.), some ten or so years hence, when almost all cars in the United States will be fitted with catalytic converters. The attachment rate of fine automotive sulfuric acid aerosols to ambient aerosols is examined. The dispersion and deposition of automotive sulfate are modelled over the highway for 'worst case' meteorology using K-theory. The neutralizing effect of ambient ammonia on sulfuric acid concentrations around the highway is examined by a direct simulation procedure for dispersion calculations. These calculations indicate that adverse environmental effects of automotive sulfuric acid emissions may be important under the stated conditions of this study.
