Article Preview

By means of AAS analysis method, a study on the concentrations of Pb, Cd in the plants of four different species of plants and soils in the polluted sites by zinc smelting in north-west GuiZhou Province. The fractions of heavy metals in the soils were distinguished by the sequential extraction prcedure as mobile fraction and residual fraction. Heavy metal concentrations in the plant were found linearly increased with their concentrations in soils around plant rhizosphere. The concentrations of Pb and Cd in the four plants followed the order Pb > Cd. Sambucus Chinensis and Ixeris gracilis were proved to have good metal-enriched and transport abilities. These plants would be useful to recover the ecology in these heavy metal polluted regions.
