title: [Establishment and application of four-dimensional fluxes emission factor model for construction fugitive dust].
abstract: We established a four-dimensional fluxes mathematics model and a suit of relevant monitoring project that can calculate construction fugitive dust emission according to actual field monitoring data, this mathematics model is similar to exposure profiling method recommended by U.S. EPA. Four-dimensional fluxes mathematics model is simpler and more convenient to calculate construction fugitive dust emission, and it can preferably eliminate the influence of incidental factors on calculation result. Actual field monitoring data from forty construction sites of Beijing were inputted into the model to calculate TSP emission factor among construction fugitive dust of Beijing local which equaled to 0.492 kg/(m2 x 30 d). By comparing emission factor of Beijing and U.S. EPA's AP-42 documents, we found the ratio between Beijing's and U.S. EPA's emission factor value was 1.83. Beijing local emission factor from this paper is recommended to establish construction fugitive dust emission inventory of Beijing.
