Based on special condition,it analyzes the simulated eluviation response of the three heavy metal element(Cr,Cu,Zn)in riverway deposit of Huaihe River on Huainan District,and the relation on the characteristic of riverway deposit with heavy metal eluviation.

to heavy metal contaminated sewage river sediment.

Mercury,arsenic and antimony are common items in soil and river sediment samples in environment monitoring.

The Korean r iver sediments have much lower TIC,C a and carbona te contents than Chinese river sediments,whereas the Changjiang sediment is cha racterized by hi gh Ti content and the Huanghe sediment by h igh Ca,Na and car bonate contents.

In terms of the geochemical distribution and seasonal variation of N, P and trace heavymetals in the sediments, Brisbane, Australia, this paper discusses some research methods applica-ble to environmental geochemistry of river sediments, and the mechanism of river pollution, pro-viding the important scientific basis for river evaluation and environmental arrangement control.

In this study,the release behaviors of oxygen-depletion materials,including of amount and rate,and influence conditions of organic pollutants in Haipo River estuarine sediments,which acted as the index of organic pollutants,were investigated.
