Effort is underway within the Environmental Protection Agency (EPA) to determine the magnitude of the air toxics emissions form motor vehicles, specifically, all air carcinogens for which EPA has unit risk estimates and are emitted from motor vehicles. Specific pollutants and pollutant categories which are discussed include diesel particulate, formaldehyde, benzene, gasoline vapors, gas phase organics, organics associated with gasoline particulate, dioxins, asbestos, vehicle interior emissions, and metals. This paper summarizes information contained in an EPA technical report. The authors present a summary of the aggregate risk from mobile source air toxics emissions, together with the limitations inherent in the estimate.
