TRANSLOCATION AND TRANSFORMATION OF HEAVY METALS IN WATER LOGGED AERATION ZONE OF SOIL
重金属污染物在下包气带饱水条件下迁移转化的研究

The valence states and the movement of several heavy metals in waterlogged aeration zone of soil were studied and the mobilities of these metal appeared to be in following order, Cr2O72- > AsO2 > Hg2+ > Cd2+ > Pb2+. soil structure showed to be an important factor effecting the movement of the metals.
