Multi-Year Hydrochemical Variability and Metal(loid) Risk Across River, Groundwater, and Irrigation Systems of the Yarlung Zangbo River Basin, Tibet
Water quality in high-elevation agricultural river valleys is shaped by regional environmental gradients and localized hydrogeochemical conditions, but multi-year assessments often do not clearly separate routine hydrochemical variability from metal(loid) risk. This study evaluates a public multi-year dataset from the...
