The Raohe River at the intake of Lake Poyang, is one of the most seriously polluted areas in the Lake Poyang Basin. This paper was based on a survey of heavy metal concentration and migration characteristics in wa ter, sediment, soil, and aquatic plants from this area in March, 2005. The results indicate that the content of the heavy metals Cu, Zn and Cd in the water in the investigated areas meet class ]J[ criterion for surface water evalu lion. Pb, however, did not meet this criterion. The average concentration of Zn and Cd in sediment and soil in the sampling sites did not meet class ]II criterion for soil evaluation, but the average sediment and soil concentration of Cu and Pb did meet. The index of geography accumulation results indicate that zinc contamination has reached a moderately advanced stage of pollution, and the other metals such as Cu, Pb, and Cd only superficially pollute the sediment. The three heavy metals Cu, Zn, and Pb in sediment and soil show a positive correlation. Different kinds of aquatic plants in the sampling sites had dilTerent enrichment by the different heavy metals Cu, Zn, and Pb. Ac cording to the assessment of enrichment coefficient, the average enrichment coefficient of Cu contamination in a quatic plants was relatively higher than Pb and Zn. Most aquatic plants in Raohe River of Lake Poyang resisted contamination by Cd.
