ABSTRACT

ABSTRACT:   PM2.5 is a major pollutant in the harbor area. The adoption of chemical mass balance model for PM2.5 source profiles is an important way to reduce particulate matter pollution and research on the composition of particulates is the basis of the chemical mass balance model. This study collected fugitive dust (yard dust, resuspended dust, road dust, soil dust, construction dust) samples in the Tianjin port area. First, PM2.5 samples were collected with the resuspension sampler. Then, the PM2.5 source profiles of fugitive dust were established, based on which analysis and research on the characteristics of the composition spectrum were done.
