Abstract

The monitoring of total gaseous mercury (TGM) concentrations together with other trace gases and meteorological parameters was made at hourly intervals over 2-year period (1 January 2010 to 31 December 2011) at four urban monitoring sites: Guro-gu (G), Nowon-gu (N), Songpa-gu (S), and Yongsan-gu (Y) in Seoul, Korea. The mean concentrations of TGM at these sites were found to span the range of 3.28 (Y) to 3.47ngm-3 (N). Inspection of the seasonal patterns indicates that the maximum concentrations (ngm-3) occur at different times of year across the four sites: winter at N (3.67±1.77), fall at S (3.64±1.12), summer at G (3.61±1.51), and spring at Y (3.40±1.26). The long-term trend in Hg concentrations, when also considering data sets from previous studies, suggests modest reductions in concentrations at all four sites, from 2.89 to 4.49ngm-3 in 2004 and from 2.49 to 3.42ngm-3 in 2011.
