Abstract | Rare earth elements (REEs) are not only important strategic resources, but also have important research significance in tracing the sources of rocks, minerals, sediments, and other materials due to their unique geochemical properties. In recent years, with the increasing use of REEs in modern society, anthropogenic REEs have attracted widespread attention from scholars at home and abroad through different pathways into environmental media such as the atmosphere, water and soil. Gadolinium (Gd), one of the most widely used REEs, is commonly used as Gd-based constrast agents (GBCAs). Since the application of GBCAs in the 1980s, their use has increased year by year. However, GBCAs are highly hydrophilic and stable, and they are difficult to remove in conventional wastewater treatment; the vast majority of them can directly enter urban and surrounding waters. Since Bau and Dulski first reported positive Gd anomalies in the Rhine River in Germany in 1996, anthropogenic Gd, an emerging contaminant, has now been detected in surface waters worldwide. However, there are relatively few studies on anthropogenic REEs, and the direct determination of them is difficult due to the constraints of detection techniques, and traditional methods for estimating anthropogenic REEs are inevitably subject to varying degrees of error.Since its introduction in the 1980s, inductively coupled plasma-mass spectrometry (ICP-MS) has shown great potential for trace multi-element analysis due to its high sensitivity, low detection limits and wide linearity range. The technique combines a plasma ion source with high ionization efficiency and a mass spectrometer with the advantages of high sensitivity, rapid multi-element detection and less mass interference compared to spectroscopy in a special interface, making it a highly efficient technique for simultaneous multi-element analysis. The development of high-precision ICP-MS and its coupling techniques, has led to a revolutionary breakthrough in the study of REEs provenance indication. The ... |
