摘要：

系统地采集黄河内蒙古段上覆水、悬浮物和底泥样品，分析其中重金属元素的含量。采用地质累积指数法和潜在生态危害系数法，研究了黄河干流内蒙古段的上覆水、悬浮物和底泥的重金属沿程分布特征、污染程度和生态风险。分析结果显示：除了As元素，悬浮物中重金属元素含量总体上高于底泥中的含量。地质累积指数法评价结果表明：悬浮物和底泥属于无污染—中度污染，悬浮物总体上比底泥污染严重；潜在生态危害系数法评价结果表明：底泥和悬浮物中重金属的生态危害总体上属轻微状态；因此，生态风险指数法和地质累积指数评价结果基本一致。

Abstract:

Samples of overlying water, suspended particles and bed mud in the Inner Mongolia stretch of the Yellow River were collected systemically and their heavy metal element contents were analysed. Using methods of geo-accumulation and the potential ecological index,the heavy metal concentration, contamination degree and ecological risk of overlying water, suspended particles and bed mud along the Yellow River were studied. The results indicate that concentrations of the suspended particles are generally higher than those of the bed mud except As concentration. The results by geo-accumulation index method show that suspended particles and bed mud are in the state of no-pollution to mid-pollution, and suspended particles are polluted more seriously than the bed mud. The results by potential ecological index method indicate that heavy metal ecological hazard of bed mud and suspended particles are in a state of light-pollution. The evaluation results of the geo-accumulation index method and the potential ecological index method are almost identical.

Key words: surface water, suspended matter, bed mud, Inner Mongolia stretch of the Yellow River
