emobilization potential of several metallic elements (Cu, Zn, As, Cd, and Pb)
from mine soils amended with three stabilization materials (mine sludge,
steal slag, and limestone) was evaluated by consecutive batch leaching,
sequential extraction, and 1-D seepage flow experiments. Metallic elements
were effectively immobilized by amendments treatment for one month, as
proved by the decrement (10.6–92.7%) of the labile fraction compared to
non-amended soil. However, metallic elements were remobilized during 14
consecutive leaching and 400 PV of seepage. In particular, repeated wetting-
drying treatments during batch leaching tests and flow interruption events
during seepage flow facilitated the remobilization, as demonstrated by increase
in elution mass in effluents (gm), leaching rate (
k
, min-1) to seepage water, and
labile fraction in soil phase. Mechanism for increased remobilization potential
as affected unsteady state soil-water interaction is being investigated

Biography
Seunghun Hyun is a Professor in the Department of
Environmental Science and Ecological Engineering at Korea
University since 2006. He has received a PhD degree from
Purdue University in 2003. He had BS and MS degree from
Korea University. His expertise is of contaminant fate/clean-up
in (potentially) contaminated sites such as abandoned mines,
landfill, etc. His recent research project funded by Korean
Government is Assessing Long-Term Fate of Heavy Metal
by Understanding Nonequilibrium Characteristics of Natural
Attenuation Process.
