Characterization of the fugitive particulate emissions from construction mud/dirt carryout.

摘要: Abstract Although the fugitive dust associated with construction mud/dirt carryout can represent a substantial portion of particulate matter (PM) emissions inventory in non-attainment areas, it has not been well characterized by direct sampling methods. In this paper, research program is described that directly determined both PM10 and PM2.5 (particles ≤10 2.5 μm classical aerodynamic diameter, respectively) emission factors for from major project located metropolitan Kansas City, MO. The also assessed contribution automotive to total burden baseline test road. As part study, time-integrated continuous exposure-profiling methods were used assess PM emissions, including particle size elemental composition. This resulted overall 6 0.2 g/vehicle, respectively. within range prior U.S. Envi...
