| 中文摘要 |
| 本文根据沉积学原理和重金属的环境化学特性及国际上新发展的重金属污染评价方法与多变量图表示法--脸谱图相结合,对本溪市区段河道沉积物中重金属的污染状况及不同重金属的积累程度进行了综合性的评价研究.本研究的特点在于从脸谱图上可以直观地看出各河段不同重金属的地积累程度和污染情况.结果表明,太子河本溪市区河道沉积物中重金属污染是严重的,必须采取相应的治理措施. |
| 英文摘要 |
| Based on the sedimentation principles and environmentally chemical characteristics of heavy metal, and using internationally new methods on heavy metal pollution assessment with multi-variablegraph expression-face graph, a synthtical assessment study hasbeen made on the state of heavy metal pollution and geo-accumulation of heavy metals in Taizi river sediment in Benxi reach.The results indicated that the state of heavy metal pollution of Taizi river in Benxi reach is very serious,and appropriate counter measures should be taken. |
