【摘要】With the rapid development of urbanization and industrialization in China, a large number of pollutants are discharged into the water, and the problem of lake sediment pollution is becoming more and more serious. In order to reflect pollution status of sediments in Chaohu Lake, in the present study, forty-seven surface sediment samples were selected to analyze REE concentrations, further to estimate spatial distribution, REEs fraction, Ce-anomalies and Eu-anomalies, and potential contamination sources. Results are shown as below: the average concentration of REE in Chaohu Lake was found higher than the background value. REEs show right-tilting pattern and ΣLREE significantly enriched. ΣREE was found higher in the eastern Chaohu Lake; however, a higher level of REEs fraction was found in the western Chaohu Lake, which means extensively anthropogenic activities.
