| Abstract: | Geochemistry of 210Pb, Al, Fe, Mn and Cu of Core ZK226 in the modern Huanghe River Delta indicates that grain size in sediments is one of the primary factors that control the behavior of the metal elements. The correlation sequence of the metal elements with grain size is: 210Pb>Fe>Al>Mn >Cu in Core ZK226. Clay and hydrous iron oxide in sediment are the main factors that absorb 210Pb. Ratios of standardized 210Pbex to standardized Al, Fe, Mn and Cu are good indicators of soil erosion, and all these provide a necessary basis for the establishment of a model of soil erosion in the Huanghe River drainage basin. |
