Abstract
The study showed that the change of LREE total content in the suspended matter and surface sediment along the Baotou section of the Yellow River was very similar to that of every unstable speciation content, sum of unstable speciation content and distribution pattern and geochemistry parameters of rare earth elements, which all indicated that obviously pile-effect brought about by the REE industrial wastewater onto REE in the Yellow River mainstream, particularly LREE, but the pile-effect weakened gradually in recent years. The tendency of LREE total content, every unstable speciation content and sum of unstable speciation content was decreasing from bottom to top, which indicated that pile-up of external LREE from industry wastewater was in a fall trend on LREE of the Yellow River mainstream. And speciation and content of REE in the branch still showed that there was potential pile-up of REE, particularly LREE in the mainstream.
