The main purpose of this investigation was to monitor ambient air particles and metallic elements (Cr, Cu and Pb) in total suspended particulates (TSP) concentration, dry deposition. Furthermore, the calculated/measured dry deposition flux ratios of ambient air particles and metallic elements (Cr, Cu and Pb) were evaluated using three dry deposition models at five characteristic sampling sites for the 2009-2010. The results show that the average concentrations of metallic elements Cr, Cu and Pb in TSP were highest at Bei-shi (suburban/coastal) and the lowest at Gao-mei (wetland) among the five characteristic sampling sites during the years 2009-2010. This study also shows that the mean rates of dry deposition of metallic elements Cr and Cu were highest at Quan-xing (industrial) and lowest at Bei-shi (suburban/coastal) and Chang-hua (downtown). Finally, the Noll and Fang model was found to yield better predictions of the dry deposition of ambient air particles and metallic elements Cr and Cu than any of the other deposition models.
本研究的主要目的是监测环境空气中的颗粒物和金属元素（Cr、Cu 和 Pb）在总悬浮颗粒物（TSP）浓度、干沉降中的含量。此外，使用三种干沉降模型在五个特征采样点对 2009-2010 年环境空气中颗粒物和金属元素（Cr、Cu 和 Pb）的干沉降通量比进行了计算/测量。结果表明，在 2009-2010 年间，五个特征采样点中，Bei-shi（郊区/沿海）的 TSP 中金属元素 Cr、Cu 和 Pb 的平均浓度最高，而 Gao-mei（湿地）的浓度最低。本研究还表明，在 Quan-xing（工业）的金属元素 Cr 和 Cu 的干沉降速率最高，而在 Bei-shi（郊区/沿海）和 Chang-hua（市区）的干沉降速率最低。最后，发现 Noll 和 Fang 模型比其他任何沉积模型都能更好地预测环境空气中颗粒物和金属元素 Cr 和 Cu 的干沉降。
