To evaluate the possibly potent role of Asian Dust (AD) on the long range transport of Hg, statistical analyseswere carried out using the hourly concentration data of gaseous elemental mercury (Hg) along with relevant envi--Jae monitoring station inSeoul, Korea during Sept. 1997 to June 2002. During the study period, Hg concentrations in non-AD period rangedfrom 0.03 to 32.70 ng m-3 with a mean 5.27± 3.06 ng m-3, while those in AD period from 1.79 to 32.60 ng m-3with a mean 5.20± -3. The air quality during AD were typically deteriorated by enhanced PM10 massconcentration(by 2~ 5 times) compared to non-AD period, however comparison of the Hg concentration data indi-cates that they are not critically distinguished between events of AD and non-AD, except for the high minimumthe case of AD events, Hg and SO2 were assorted concurrently into a same factor. Evidence collected from thisstudy thus suggests that long-range transport of Hg, if occurring, is unlikely to raise statistically Hg concentration levels such as seen during AD event. However, in nighttime of winter season, Hg concentrations are higher during AD (along with PM10 levels) than non-AD period. Although such observations suggest the effect of long range transport on the enhancement of Hg concentrations, more deliberate analysis may be required to track down the effect of such mechanism in relation with various factors including the air mass transport route.
