When dissolve organic carbon presented in<br /> flooding water, element release as Cr, Pb, Ni, As, Co, Al, Cu were increased in both under condition oxidized and<br /> reduced. Pb, As, Co and Sb release were highest under reduced condition comparing under oxidized condition,<br /> meanwhile, meanwhile Cr, Cu and Al release were highest under oxidized condition.<br /> Keywords.
