    Published 2023-01-01
    “…The combination of highly selective separation techniques such as ion chromatography and highly sensitive ICP-MS has played an important role in the analysis of anthropogenic REEs, and the elemental speciation analysis capabilities of it make this one of the key research tools for the analysis of anthropogenic REEs.The progress of geochemical features of REEs such as isotopes in identifying material sources, resolving key processes and tracing environmental behavior, is summarized in this study, mainly including: (1)REEs fractionation patterns and isotopic features have been widely used in traditional provenance indication, and research is mainly based on REEs content or isotope information, combined with relevant mathematical and statistical models; (2) The speciation of REEs can provide an important basis for indicating anthropogenic activities, for example, due to the regional differences in the types of GBCAs used, there are obvious geographical differences in the speciation of anthropogenic REEs, with a high detection rate of macrocyclic GBCAs and a low detection rate of linear GBCAs in natural waters in regions such as Germany. …”
