GONG Xiao-feng1, CHEN Yao1*, YIN Li2, TANG Zhi-ping1(1.School of Environment Science and Engineering, Nanchang University, Nanchang 330031, China; 2.School of Life Science, Jinggangshan University, Ji’an 343009, China)  
Pollution level of Three River Drainage Area around Poyang Lake was studied. The contaminated sediments were collected at 7 selected sampling spots and speciation of heavy metals including Zn,Pb and Cd were analyzed by Tessier sequential chemical extraction method. Different speciation of heavy metals revealed the pollution level and distribution of heavy metals for different spots. Results showed that Three River Drainage Areas around Poyang Lake were suffered low grade pollution of heavy metals and heavy metals were associated primarily with residual phase and secondarily with oxidatal phase and carbonate phase.
