Abstract |
Ore powder had been cumulated at a moderate incline along the upper Nakdong Riverside by the natural disaster such as a flood from mines and smelting factories between 1940 and 1970. This study investigates the surface and deep layer mine tailings and the neighboring soil at 7 sites in the upper Nakdong River System.
The study analyzed the sites between 2014 and 2015 for the presence of eight heavy metals (Cd, Pb, As, Cr(VI), Hg, Zn, Cu, Mn), Generally, the content of heavy metals increased in order from the contrast soil, the deep layer mine tailings, to the surface layer mine tailings. Consequently, it was concluded that the upper region of the Nakdong Riverside requires the remediation in the near future in order to remove the mine tailings |
