| Abstract: | A quantitative method to evaluate the amounts of heavy metals in river sediments is established. Using the BT Drainage River
in North China as a study object, six representative cross sections were selected for measurement of heavy metal indicators
in sediments, and then the main contamination indicators were determined by performing a potential ecological risk assessment.
Using a section of this river as an example, the total amounts of the main pollution indicators and those of their harmful
forms are estimated by the Surfer software, which simulates the pollution status within the downstream sediments of the outfall
at this section. The calculation results could provide a theoretical guideline and data support for pollution treatment of
the BT Drainage River. |
