Abstract
The content of soluble fraction of rare earth elements (REE) in the river was limited but the content of suspended REE in the river varied over a wide range. Contents of REE in the sediments were almost the same with those in the suspended matter. REE were accumulated in fine grained particles, and this showed strong relationship with minerals. The distribution modes showed strong accumulation in the light REE with relative deficit in Eu. The partitioning characteristics of REE in the sediments and suspended matter were quite similar, with the main amount in residual forms. They obeyed the following order: residual>> bound to organic matter> bound to Fe-Mn oxides> bound to carbonates>> exchangeable. Compared with light and heavy REE, the medium REE (Eu, Sm, Tb) had relatively low percentages in the residual form and high in the forms which are bound to organic matter and Fe-Mn oxides. -from English summary
