The ambient air TSP concentrations, dry deposition fluxes, and particulate-bound mercury concentrations were measured and analyzed at a complex site. The model used to predict the dry deposition fluxes underestimated the values for all particle sizes. Better results were observed for pollutants' dry deposition fluxes as particle size increased.
Ambient air TSP concentrations, dry deposition fluxes and particulate-bound mercury (Hg(p)) concentrations were measured and analyzed at a complex (traffic, residential and commercial) site. Zhang and He's model([1]) was used to predict the dry deposition fluxes of ambient air particulates and Hg(p) at this complex site. The results revealed that October had the highest mean particulate concentration and lowest Hp(p) concentration and dry deposition flux. The mean calculated dry deposition fluxes of PM2.5 and PM2.5-10 accounted for 1%-2% and 0.06%-5% of the average total calculated dry deposition particle flux, respectively. The average calculated particle dry depositions flux of PM10+, accounted for 93%-99% of the average total calculated dry depositions particle flux. Finally, the model of Zhang and He underestimated the ambient air dry depositions fluxes of both particulates and Hg(p) for all particles sizes (PM2.5, PM2.5-10, PM10+) at the mixed site in this study. Better results concerning the dry deposition fluxes of pollutants were obtained as the particles size increased.
