Measurements of Vehicle Emissions of Speciated Carbonyls and Carboxylic Acids in Highway Tunnels
The objective of this study has been met by carrying out measurements of carbonyls and carboxylic acids in two highway tunnels. Carbonyls have been measured at the Tuscarora Mountain Tunnel in Pennsylvania, and the results are described in Part 1 of the report. Carboxylic acids have been measured at the Caldecott Tunnel near San Francisco, California, and the results are described in Part 2 of the report. Carboxylic acids play an important role in atmospheric acidity, long-range transport of airborne pollutants, and acid deposition. While vehicles are known to emit carboxylic acids, no information is available regarding the nature and magnitude of emissions of carboxylic acids by on-road vehicles. To identify carboxylic acids and measure their emission factors, a field study was carried out in July-August 1999 at the Caldecott Tunnel (a highway tunnel in the San Francisco, CA Bay Area).
