Application of Baklanov and Sorensen's Model in the Prediction of Ambient Air Particle and Metallic Elements Dry Deposition at Traffic, Industrial and Wetland Areas

Abstract

The main purpose of this study was to monitor ambient air particles and metallic elements (Mn, Fe, Zn, Cr, Cu, and Pb) in total suspended particulates (TSP) concentration and dry deposition. In addition, the calculated/measured dry deposition flux ratios of ambient air particles and metallic elements (Mn, Fe, Zn, Cr, Cu, and Pb) were evaluated using Baklanov model at a traffic, an industrial (Quan-xing) and a wetland (Gao-mei) area in Central Taiwan between 2009 to 2010. The results indicated that the mean highest concentrations of metallic elements Mn, Fe, Zn, Cr, and Cu in TSP occurred at Quan-xing industrial sampling site. The results also showed that the Baklanov and Sorensen's model exhibited better dry deposition fluxes for 10-µm particle size at these three characteristic sampling sites for all metallic elements. The metallic element Fe exhibited better dry deposition flux results for 5.6-µm particle size at these three characteristic sampling sites (when using Baklanov and Sorensen's model).
