Abstract: Shallow lakes are important freshwater resources which have the functions of flood control, transportation, agriculture, aquaculture, tourism, drinking and ecological protection. The environmental quality of shallow lakes is highly relevant to human health and sustainable development of society and economy. Rapid urbanization and economic development have resulted, progressively, in deteriorating freshwater conditions. In Jiangsu Province, there are about 200 freshwater lakes with a total surface area of 6 853 km2 that account for 6% of the total land area of this province. These lakes are all shallow lakes and are subject to disturbances by natural and human activities. In the past decades, human activities have caused serious environmental problems, such as eutrophication, heavy metal pollutions, organic pollutions and habitat degradation. In order to characterize heavy metals pollution in surface sediments of shallow lakes in Jiangsu Province, the contents of eight heavy metals (Mn, Zn, Cr, Ni, Cu, As, Cd and Pb) in surface sediments from eight shallow lakes were measured by inductively coupled plasma-atomic emission spectrometer (ICP-AES) and mass spectrometer (ICP-MS), and the geo-accumulation index and the Hkanson potential ecological risk index were applied for assessing the status of sediment heavy metal enrichment and the extent of potential ecological risk. The average content of heavy metals in surface sediments of these lakes were in the range of 634-1 031, 66-138, 76.0-97.5, 39.2-56.3, 25.2-50.1, 9.9-27.1, 0.15-2.98, and 24.6-51.6 mg/kg for Mn, Zn, Cr, Ni, Cu, As, Cd, and Pb, respectively. The results from correlation analysis showed that Cr and Ni have the similar origin with Mn, Zn, Cu, Pb, respectively. The results of geo-accumulation index indicated that Cd was the main pollutant in surface sediments of these lakes, Zn, Cu, As, Pb and Ni caused light pollution in some lakes, and Mn and Cr were at a clean level. For the different lakes examined in the present study, the general indices of potential ecological risk followed the order of Changdang Lake> Shijiu Lake> Baima Lake> Gehu Lake> Gaoyou Lake> Hongze Lake> Chenghu Lake> Luoma Lake. Changdang Lake reached the serious ecological risk level, and heavy ecological risk existed in Shijiu Lake. Baima Lake and Gehu Lake had moderate ecological risks, while Luoma Lake, Hongze Lake, Gaoyou Lake and Chenghu Lake imposed low ecological risks.

Key words: shallow lakes, surface sediments, heavy metals, pollution characteristics, potential ecological risk
