  • 摘要: 从苕溪流域景观单元角度研究重金属污染特征,因人类活动是重金属污染的主要来源,所以在苕溪流域内选择采集典型工业区、农业区和城镇生活区附近河道的沉积物,分析各典型区域重金属Pb、Cd、Cr、As、Hg、Cu和Zn的含量特征,并用潜在生态危害指数法评价。结果表明,按照《土壤环境质量标准》,苕溪流域典型工业区主要是Hg、Cu和As的污染,典型农业区和城镇生活区主要是Hg的污染。各元素间的相关性分析表明,在工业区:Zn-As、Zn-Pb和As-Pb之间存在相关关系,说明它们的同源性很高。在农业区:Cu-As、Cu-Cd之间存在显著相关关系,其来源有可能相似。在城镇生活区Zn-As、Zn-Cd之间存在很高的相关性,说明它们有很高的同源性。由多种重金属潜在潜在生态风险评价结果可知:苕溪流域典型工业区、城镇区和农业区的沉积物处于低潜在生态风险。
    Abstract: Because human activity is the main source of heavy metal pollution, sediments are carried in living area, industrial area and agricultural areas from perspective of landscape unit, the content and characteristics of seven heavy metals(Pb, Cd, Cr, As, Hg, Cu, Zn) of three typical areas sediments in Tiaoxi River. Ecological risk index was utilized. The results showed that the sediments of typical industrial were polluted mainly by Cu,Hg and As compared with the environmental quality standard for soils, and for the typical living area and agricultural aera, there are mainly Hg pollution. The results of correlation of typical industrial areas analysis show correlation among Zn, As and Pb, which suggest their origin is the same. As to typical agriculture area, correlation exists between Cu, As and Cd, which suggest their origin is the same.As to typical living area correlation exists Zn, As and Cd, which suggest their origin is the same. Based on the potential ecological risk assessment results, sediments from the three typical areas are clean or low-risk status, good sediment quality.
