In October 1976 a two-week field program was conducted in Los Angeles to evaluate in the field existing measurement methods for ambient concentrations of sulfuric acid aerosol and related sulfates, and to obtain preliminary data for the in-roadway concentrations of sulfates due to catalyst equipped vehicles. Scatter diagrams show that the in-roadway increments of NOx, CO, SO2 and several aerosol physical parameters do not correlate well. The statistical design of an in-roadway sampling program to determine distribution functions for the exposure of the Los Angeles population to elevated concentrations of vehicle exhaust pollutants is described.
