It has been well known that the free ion concentration of metals plays a vital role in metal bioavailability. However, measurement of this fraction is still not easy over years of development. Nowadays, rare earth elements (REEs) are drawing more attentions as an emerging contaminant due to their wide applications in our daily life.

- Rare-earth elements (REEs) are emerging pollutants, yet their geochemistry in rivers affected by ion-adsorption mining is understudied.
- Samples collected from a mining-impacted river showed significantly higher concentrations of REEs in smaller water fractions (<0.45 μm) compared to a control site, with varying factors affecting REE distribution between upstream and downstream.
- The study found that upstream REE transport was influenced by ligand complexation and smaller colloids, while downstream concentrations were driven by larger colloids and particle adsorption, highlighting the importance of REE patterns for understanding their behavior in mining-affected areas.
