| 摘 要： | 对1993年～1999年所采集的太湖表层沉积物中重金属含量进行了统计分析和生态风险性评价.结果表明,太湖沉积物的pH值呈中性至弱碱性,较适合于沉积物中粘土矿物及腐殖质对重金属的吸附;太湖大部分地区沉积物未受到重金属污染,且沉积物中重金属处于安全状态.沉积物生态风险性指数评价结果也表明,太湖大部分地区目前无重金属生态危害.

| Abstract: | The content of heavy metal in sediment of the Taihu Lake, sampled within 1993 and 1999, was analyzed, and its ecological risk was evaluated. The pH of sediment of the Taihu Lake was neutral to weak alkalinity, it was advantageous to the heavy metal absorption of clay mineral and humus. In most place in the Taihu Lake, sediment had not polluted by heavy metal, and heavy metal in sediment was in safety. The ecological risk assessment of sediment indicated that there had not ecological crisis of heavy metal in the Taihu Lake. |
