对评价河流颗粒物重金属污染水平的4种方法进行了比较研究;提出了适用于Igeo法和SEF法评价我国河流颗粒物重金属污染水平的评价参比标准值;并应用这些方法对我国部分河流颗粒物重金属的污染水平进行了评价。

Assessment of particulate quality clearly reveals its prominent role in heavy metal cycling. For this reason, two new methods(RSP and PEF)are put forward. Combined with preceding literature, four methods are compared. Based on assessment results of main rivers of out country, the paper proves that most of rivers are not seriously contaminated by heavy metal due to their strong buffer capacity. The aim of this paper is to provide theoretical reference for further studies and to provide appropriate selection for particulate quality assessment under different situations.
