The focus of this study is to observe the seasonal variations of particulate bound mercury Hg(p) concentration and amount of Hg(p) (ng/g) in total suspended particulates (TSP) and dry deposition at two (industrial and wetland) characteristic sampling sites in Taiwan, during the years 2009-2010. Concentrations of Hg(p) from each sample (quartz filter, overhead projection film) were analyzed by a direct Hg(p) analyzer DMA-80. Approximately 30 mg of the filter sample was loaded directly into the DMA-80 and analyzed. The results indicated that the mean highest Hg(p) in TSP (expressed in ng/m(3)) and dry deposition (expressed in ng/m(2)/min) both occurred at the industrial site (Quan-xing) while the corresponding mean lowest Hg(p) concentrations occurred at the wetland site (Gao-mei). Also, the mean highest amount of Hg(p) (expressed in ng/g) in TSP and dry deposition occurred at the industrial site (Quan-xing), while the mean lowest amount of Hg(p) occurred at the wetland site (Gao-mei). Metal products manufacturing and heavily loaded traffic during weekdays were possible sources responsible for the high concentrations of Hg(p) observed at Quan-xing (industrial) sampling site.
