Pollution and Potential Biological Toxicity Assessment Using Heavy Metals from Surface Sediments of Liangtan River, Chongqing, China

Abstract: The concentrations of heavy metals (Cu, Zn, Pb, Cd, Ni, Cr, As) in the surface sediment of Liangtan River were determined by using atomic absorption spectrometry (AAS) and atomic fluorescence spectrometry (AFS), and the toxic effects and sediment pollution assessment were conducted systematically by using Sediment Quality Guidelines (SQG), Hakanson Potential Ecological Risk Index. Moreover, the underlying source of heavy metal was analyzed. The results indicated that the concentrations of Cu, Zn, Pb, Cd, Ni, C… Show more
