| 摘 要： | 本研究对太湖上游集水区重要城市常州城区河网的12条主要河流开展了城市主要河道沉积物中的重金属分布状况及特征调查,采用Hakanson生态风险指数法对沉积物中的主要重金属对所在水域的污染程度及对水域和周围环境造成的潜在风险影响进行了评价。结果显示,常州河道沉积物已受到严重污染,不同类型河道的沉积物污染程度趋势为:城区>郊区>城市外围河道,其中以Hg的污染最重。 |
| 关 键 词： | 河流 沉积物 重金属 生态风险 |

| Abstract: | Twelve main rivers were chosen for the investigation of heavy metal distributions and specifications.Hakanson Potential Ecological Risk Indexes were calculated and used as criteria for pollution and potential risk evaluation.The results indicate that the sediments of rivers in Changzhou are severely contaminated.The degree of contamination is urban>rural>outside,while Hg pollution is the most contaminating factor. |
| Keywords: | river sediment pollution heavy metal ecological risk |
