SIZE CHARACTERIZATION OF SULFURIC ACID AEROSOL EMISSIONS

In the course of a vehicle dynamometer study of sulfur emissions from an automobile equipped with oxidation catalysts, aerosol size distribution measurements were made while the exhaust was rapidly mixed with 10 parts of filtered air in a dilution tube. Results obtained with an electrical aerosol analyzer show that, under these dilution conditions, the sulfuric acid aerosols are consistently smaller than 0.3 um in diameter. Within a reasonable margin of error, consistency is found between cascade impactor data, nephelometer light-scattering data, electrical analyzer data, and chemical analyses for sulfate. /GMRL/
