We provide a new generalized framework accounting for the effects of water and nutrient uptake by roots in weathering zone on broad patterns solute concentration - discharge relationships rivers. As plants withdraw from subsurface, they decrease area-normalized fluid drainage rate.

Constraining the processes that fractionate barium isotopes is essential for utilising isotope ratios as environmental tracers. Barium concentration measurements from soils, rivers, and estuaries demonstrate adsorption–desorption reactions significantly influence distribution of fluid-mobile at Earth's surface, potentially driving isotopic fractionation. To quantify direction magnitude fractionation resulting these reactions, a riverine an estuarine series batch experiments were conducted using environmentally important adsorbent minerals surface waters. Himalayan river sediment water samples used to validate experimental results. Adsorption–desorption found be rapid, relative average transit time in catchments, largely reversible. The experiment consistent with field (preferential adsorption lighter isotopes). reaction rate, reversibility, depend primarily on mineral. Experiments performed iron oxyhydroxides (goethite ferrihydrite) resulted greater degree compared clay (kaolinite montmorillonite). Estuarine experiments, designed simulate passage through salinity gradient, demonstrated high 77% 94% adsorbed desorbed upon addition seawater freshwater–equilibrated minerals. results suggest measured marine paleo–archives (e.g., corals) will reflect both dissolved freshwater inputs ocean. combined findings this study indicate chemical behaviour differs more conventional group 1 2 metal systems due significant proportion released bedrock dissolution partitioning mineral surfaces, rapid rates between phases, reversibility. Consequently, are likely provide unique insights into complex array terrestrial weathering erosion sustain life Earth.
