- Abstract
- The purpose of this report is to provide a methodology with which to project areawide total particulate emissions from mobile sources in a given calendar year. Particulate emissions can consist of lead salts, organics and sulfate emissions. The relative amounts vary for different vehicle types, emission control strategies and vehicle operating modes. Analysis of lead particulate indicates that most of the exhausted lead appears as PbClBr. Therefore estimates of the mass lead particulate will be considerably larger than those predicted by the lead document. Organic emissions include both soluble organics and elemental carbon and are important contributors to total particulate emissions from all vehicles especially dieseles. Sulfate emissions, mostly from unleaded gasoline-fueled vehicles equipped with catalysts, are also important contributors to total vehicular particulate emissions.
