Measurements of size-fractionated concentration and bulk dry deposition of atmospheric particulate bound mercury

► Highest concentrations for ambient particulate mercury (Hg(p)) were observed in early winter. ► PM1.0 and PM1.0-2.5 dominated the bulk Hg(p) concentration. ► Coarse Hg(p) contributed 7-25% of the bulk Hg(p) concentration. ► Coarse Hg(p) contributed 50-85% of the total Hg(p) dry deposition. ► Dry deposition velocity of Hg(p) was mostly in the range of 0.1-0.8 cm s−1.
