Abstract：In order to investigate the seasonal,annual and alongshore variation of the trace elements in the sediments of Poyang Lake in recent years,ICP-AES was used to determine the sediment of each sampling site collected in the year of 2003 and 2005 in different seasons.The results indicated that the contents of the elements in the sediments of Poyang Lake were changing with seasons and years. Generally,the content of each element in low-water period was more higher than in high-water period. Compared with the year of 2003,the contents of Cu and Pb at Nan Ji-shan were lower in the year of 2005,while Cai Jia-wan was in the reverse situation. The content of Cu at Yao Gong-du was also lower in the year of 2005,but Pb was higher than in the year of 2003. To some extent,the contents of Cu,Pb,Cr and Zn were higher than the background value of Poyang Lake basin. Except Dawu River,the content of As at other sampling sites was within the background value. From Raohe River to the Raohe River’s entry in Poyang Lake,the content of each element trended to decrease gradually. By using microwave-assisted-ICP-AES to determine the trace elements in the sediments of Poyang Lake,it was proved to be a simple and fast,efficient method.
