The main purpose of this study was to monitor ambient air particles and particulate-bound mercury Hg(p) in total suspended particulate (TSP) concentrations and dry deposition at the Hung Kuang (Traffic), Taichung airport and Westing Park sampling sites during the daytime and nighttime, from 2011 to 2012. In addition, the calculated/measured dry deposition flux ratios of ambient air particles and particulate-bound mercury Hg(p) were also studied with Baklanov & Sorensen and the Williams models. For a particle size of 10 μm, the Baklanov & Sorensen model yielded better predictions of dry deposition of ambient air particulates and particulate-bound mercury Hg(p) at the Hung Kuang (Traffic), Taichung airport and Westing Park sampling site during the daytime and nighttime sampling periods. However, for particulates with sizes 20-23 μm, the results obtained in the study reveal that the Williams model provided better prediction results for ambient air particulates and particulate-bound mercury Hg(p) at all sampling sites in this study.
本研究的主要目的是在2011年至2012年期间，对白天和夜间在弘光（交通）、台中机场和西屯公园采样点的环境空气颗粒物以及总悬浮颗粒物（TSP）浓度和干沉降中的颗粒态汞Hg(p)进行监测。此外，还使用Baklanov & Sorensen模型和Williams模型研究了环境空气颗粒物和颗粒态汞Hg(p)的计算/测量干沉降通量比。对于粒径为10μm的颗粒物，Baklanov & Sorensen模型在白天和夜间采样期间，对弘光（交通）、台中机场和西屯公园采样点的环境空气颗粒物和颗粒态汞Hg(p)的干沉降给出了更好的预测。然而，对于粒径为20 - 23μm的颗粒物，该研究结果表明，Williams模型对本研究中所有采样点的环境空气颗粒物和颗粒态汞Hg(p)提供了更好的预测结果。
