Analysis and Assessment on Heavy Metal Contamination of Tuo River in Suzhou
Abstract:
River sediment is a basic composition part of water environment, the heavy metal content of which is usually taken as one of the important index for the water environment quality. Taking the water quality and sediment of the Tuo River in Suzhou in this article as the main research objects, the research on pollution of heavy metals was carried out. Along the river, it is divided into S, U, F, D, O five blocks from upstream to downstream, and each area was arranged 6 to 11 sampling points unequally. The content of heavy metals (P, Hg, Al, Fe, V, Cr, Co, Zn, and Cu) which existed in the water and sediment were tested and analyzed. Moreover, heavy metal pollution of Tuo river sediment was evaluated by the methods of Geoaccumulation index and Potential ecological risk assessment.
