The Monitoring and Ecological Evaluation of Beng River Sediment for Heavy Metals (Hg,Pb,Cr)

Abstract:

In order to analysis the Heavy metals in the bottom mud at beng river, we put the river reach between the bridge of beng river beside the er’huang road and the bridge beside the yin’meng road as the main research object, survey 14 transects of bottom mud from three indications (Hg,Pb,Cr) of the river and build a relate standards about the pollution of bottom mud depend on the domestic standards, in this paper, we use the potential ecological risk index method which was putted forward by Swedish scientists Hakanson as the criterion of the pollution about heavy metals in the mud. The results show that: at the rive reach mentioned above, we found there are very high heavy metals content in the bottom mud.
