초록 BACKGROUND: Heavy metals (Al, As, Cd, Cr, Cu, Li, Hg, Ni, Pb, and Zn) were analyzed to elucidate the impact of weir construction on their concentrations in sediments of Geum River, Korea. We also attempted to investigate the source of the heavy metals in sediments. METHODS AND RESULTS: For this study, sediments were collected from May through June in 2012. The concentrations of heavy metals except Hg were determined by inductively coupled plasma mass spectrometer, and Hg was measured by automatic mercury analyzer. More clay were accumulated in the furthest stations in the upstream direction starting from the weirs. Most of the heavy metals showed higher concentrations in the most upstream located station of Geumnam Weir. However, high concentrations were not observed in the most upstream stations of the other weirs. The concentrations of Hg and As were much higher in sediments of Gap Stream. CONCLUSION: Gap Stream may be a potential source for high deposits of As and Hg. Presence of the dams may not play an important role in controlling heavy metal concentrations in sediments. It is necessary to monitor heavy metal concentrations for a longer time period to study the effect of environmental changes on heavy metal distribution in Geum River.
