摘要
通过对纳工业废水为主的荆马河和纳生活污水为主的废黄河底泥重金属进行地累积指数污染评价、潜在生态危害评价、污染成因和底泥重金属质量分数的相关性分析,得出荆马河重金属的污染程度和潜在生态危害程度明显重于废黄河,重金属的来源不同,但其相关性相似.针对不同成因,对两河重金属污染提出了相应的治理措施建议.
Assessing the geoaccumulation index and the potential ecological risk,and analysing the relativity between the pollution causes and the mass fraction of heavy metals in sediment of two rivers,the Jingma River which receives industrial wastewater and the Old Course of the Yellow River which receives domestic sewage,we conclude that the heavy metal pollution and potential ecological risk are more severe in the Jingma River than in the Old Course of the Yellow River.Corresponding measures are suggested for the two rivers which receive different wastewater.
