The main purpose for this study is to observe the seasonal and month variations for particulates-bound mercury Hg(p) in total suspended particulates (TSP) concentration, dry deposition at five characteristic sampling sites during years of 2009-2010 in central Taiwan. The results show that the highest and lowest monthly average particulates-bound mercury Hg(p) concentrations in TSP were occurred in Dec. and Oct. at Gao-mei (wetland), Chang-hua (downtown) and He-mei (residential) sampling site. In addition, the results show that the highest and lowest monthly average particulates-bound mercury Hg(p) dry deposition was occurred in Feb. and Oct. at Quan-xing (industrial) sampling site. This study reflected that the mean highest particulates-bound mercury Hg(p) concentrations in TSP and mean highest particulates-bound mercury Hg(p) dry deposition were occurred at Gao-mei (wetland) and Quan-xing (industrial). However, the mean lowest particulates-bound mercury Hg(p) concentrations in TSP and mean lowest particulates-bound mercury Hg(p) dry deposition were also occurred at Gao-mei (wetland). Regarding seasonal variation, the order of mean-particulates-bound mercury Hg(p) concentrations in TSP in winter and spring were Gao-mei (wetland) > Quan-xing (industrial) > Bei-shi (suburban/coastal) > Chang-hua (downtown) > He-mei (residential). Finally, the order of mean-particulates-bound mercury Hg(p) dry deposition in fall, spring and summer were Quan-xing (industrial) > Bei-shi (suburban/coastal) > Chang-hua (downtown) > He-mei (residential) > Gao-mei (wetland).
本研究主要目的在观察 2009-2010 年中台湾五个特征采样点在总悬浮微粒（TSP）中汞（Hg）之季节性与月变化及干沉降。结果显示，在高美（湿地）、彰化（市区）与和美（住宅）采样点，TSP 中汞（Hg）之月平均浓度最高值出现在 12 月，最低值则出现在 10 月。此外，在泉兴（工业区）采样点，汞（Hg）之月平均干沉降量最高值出现在 2 月，最低值则出现在 10 月。本研究显示，TSP 中汞（Hg）之平均浓度最高值及汞（Hg）之平均干沉降量最高值均出现在高美（湿地）采样点，然而，TSP 中汞（Hg）之平均浓度最低值及汞（Hg）之平均干沉降量最低值亦均出现在高美（湿地）采样点。在季节性变化方面，TSP 中汞（Hg）浓度之平均值在冬季及春季时的顺序为高美（湿地）>泉兴（工业区）>北势（郊区/沿海）>彰化（市区）>和美（住宅）。最后，在秋季、春季和夏季，汞（Hg）干沉降之平均值顺序为泉兴（工业区）>北势（郊区/沿海）>彰化（市区）>和美（住宅）>高美（湿地）。
