Abstract
A comprehensive study of exhaust and evaporative emissions from light duty vehicles was performed in Los Angeles, CA; and St. Louis, MO, to determine the contribution to atmospheric pollution by 1966 through 1972 model year vehicles. This study was part of a total effort to measure the emissions from light duty vehicles in six cities. Exhaust emissions tests on 170 vehicles in Los Angeles, CA; and St. Louis, MO, and evaporative emissions tests on twenty 1972 model year vehicles in Los Angeles, CA were performed. These tests determined the levels of hydrocarbons, carbon monoxide, carbon dioxide and oxides of nitrogen exhaust emissions as well as hydrocarbon evaporative emissions.
