The historical impact of motor vehicle and stationary source emissions on ambient air pollution concentrations and the degree of accuracy with which present scientific information and methodology predict the impact of alterations in emission patterns on ambient air quality were studied. Emission inventories, atmospheric processes (including transport, dispersion, chemical transformations, and removal processes), monitoring ambient air quality (instrumentation, site selection, data collection, and stations), trends in emissions (sulfur oxides, particulates, carbon monoxide, nitrogen oxide, and nonurban and urban photochemical oxidants), models for predicting ambient air quality and their applications, and applications of modeling to air quality strategy for carbon monoxide and chemically reactive pollutants are discussed. The following questions are discussed: Are there nationwide emission data which accurately characterize emission trends. Are there nationwide air monitoring data which adequately characterize ambient air quality. What influence have control measures had on emission trends. What techniques exist for predicting the relationship between emissions and air quality. What is the recommended method for relating emissions to air quality for each of the motor vehicle pollutants. Are the present motor vehicle emission standards set at an appropriate level in order to meet the ambient air quality standards for CO, hydrocarbons, nitrogen oxides, and oxidants.
