| Abstract: | Analysis of Zn, Cu, Pb, Co, Cr, Li, Ni, K, Al, Fe extracted by 1 mol/L HCl or 0.5 mol/L HC1/H2O2 showed concentrations of Zn, Cu, Pb, Co, Cr, Fe, Ni were significantly correlated with Li, Al, K, and clay. Two methods are used to indicate the background value of the non-residual phase of elements in sediments, and are the same as the methods used to indicate the background value of total concentrations in sediments. The first method uses correlograms and regression equations, the second uses the mean element concentrations normalized with grain size.Li, Al, K can be used as reference elements to determine the background value of Zn, Cu, Pb, Co, Cr, Ni, Fe, while the clay concentration's correlation with some extractable concentrations can be used to calculate the background value of the non-residual phase of elements as a percentage of clay concentration in the sediments. Based on this study, the concept of using the background value of the non-residual phase of elements to compare the pollution level in differ ent areas is advanced as a very important method for further research. |
