| Abstract: | Concerns have been raised on iron and manganese levels which were found exceeding the national standards in Yongjiang River,the main drinking water source of Nanning City,Guangxi.GM(1,1) and T-E-S model were respectively used to calculate the concentrations of Fe and Mn from 2006 to 2008 in Chencun,a section cross of Yongjiang,based on monitoring data from 2001 to 2005,and then a combined model was developed to predict Fe and Mn levels in the same areas.Results showed that the relative error of Fe concentra... |
