Richards, L W; Johnson, K R

An instrumented van was used to collect size-segregated aerosol samples and measure sulfur dioxide and ammonia concentrations on the heavily-traveled Ventura Freeway in Los Angeles while a nearby identical van in radio contact sampled upwind. Measurements were made on a few unusually clean days in October 1978 and February 1979 so that the in-roadway sulfate increment (freeway minus upwind background) could be detected. Sulfuric acid emissions were easily measured behind a new, catalyst-equipped vehicle using fuel with 10 times the California average sulfur content.
