| Abstract: | Contents of heavy metals in surface sediment of Nansha River were determined.Index of geoaccumulation of heavy metals in sediment was assessed,and results showed that the index of geoaccumulation which was classified as degrees 0 ~4 indicated the contamination levels from non to partial serious pollution,with the ranking of various heavy metals pollution from high to low in turn as Zn,As,Se,Cu,Pb,Sb,Ni,Cr,Co,V and Tl.Results of principal component analysis(PCA) showed that heavy metals in the sediments came... |
