Six source categories for PM2.5 reviewed: on-road mobile sources, nonroad cooking, biomass combustion, fugitive dust, stationary sources. Ammonia all the also examined. Regional PM in exhaust sources generally consistent ambient observations, though uncertainties some emission factors twice as large factors. In contrast, road dust up to an order magnitude larger than estimated brake wear tire half observations urban areas. Although comprehensive nationwide cooking biomas...
