East Asia contributes to nearly 50% of the global anthropogenic mercuryemissions into the atmosphere. Recently, there have been concerns about thelong-range transport of mercury from East Asia, which may lead to enhanceddry and wet depositions in other regions. In this study, we performed fourmonthly simulations (January, April, July and October in 2005) using CMAQ-Hgv4.6 for a number of emission inventory scenarios in an East Asian modeldomain. Coupled with mass balance analyses, the chemical transport ofmercury in East Asia and the resulted mercury emission outflow wereinvestigated. The total annual mercury deposition in the region wasestimated to be 821 Mg, with 396 Mg contributed by wet deposition and 425 Mgby dry deposition. Anthropogenic emissions were responsible for most of theestimated deposition (75%). The deposition caused by emissions fromnatural sources was less important (25%). Regional mercury transportbudgets showed strong seasonal variability, with a net removal of RGM(7–15 Mg month−1) and PHg (13–21 Mg month−1) in thedomain, and a net export of GEM (60–130 Mg month−1) from thedomain. The outflow caused by East Asian emissions (anthropogenic plusnatural) was estimated to be in the range of 1369–1671 Mg yr−1,of which 50–60% was caused by emissions from natural sources. Theemission outflow represented about 75% of the total mercury emissions inthe region, and would contribute to 20–30% of mercury deposition inremote receptors
