• dry deposition
• total suspended particulate (TSP)
• season

The main purpose of this study is to observe the seasonal variations of total suspended particulates (TSP) concentration, dry deposition (and the metallic elements that attach to them) at five characteristic sampling sites in Taiwan during the years of 2009 and 2010. The highest average concentration in TSP for metallic elements Mn and Fe occurred in Quan-xing (industrial area), while the highest average concentration in TSP for metallic elements Cr, Cu, and Pb was observed in Bei-shi (suburban/coastal area). The lowest average concentrations for metallic elements in TSP occurred in Gao-mei (wetland area). In addition, the highest average dry deposition for metallic elements Mn, Fe, and Zn was observed in He-mei (residential area). Also, the highest average dry deposition for metallic elements Cr, Cu, and Pb occurred in Quan-xing (industrial area). The lowest average dry deposition for metallic elements Mn, Fe, and Cr occurred in Bei-shi (suburban/coastal), while the lowest average dry deposition for metallic elements Zn, Cu, and Pb was observed in Chang-hua (downtown). Regarding seasonal variation, the results show that the average seasonal dry deposition order for metallic elements Zn, Cr, and Pb was fall spring winter at Bei-shi (suburban/coastal), Chang-hua (downtown), He-mei (residential), and Gao-mei (wetland). Finally, the average seasonal concentration order for Cu in TSP was fall winter spring, at Bei-shi (suburban/coastal), He-mei (residential), Quan-xing (industrial), and Gao-mei (wetland) sampling sites.
