Behaviour of Cr in runoff from two catchments underlain by felsic bedrock
Original language description
Chromium isotope and chemical compositions in runoff from two felsic rock catchments, the Lysina (LYS; Czech Republic) and the Neglinka (NEG; northwest Russia), were studied. Three types of water were identified: Na-Ca-SO4 type for the LYS, Mg-Ca-Cl-HCO3 type for the NEG downstream, and Mg-Ca-Cl to Mg-Ca-HCO3 type for the NEG upstream. The Cr(III) liberated during soil/bedrock weathering oxidized to Cr(VI), which was the main dissolved Cr species in both catchments. Variations in d53Cr values for LYS runoff (–0.07per mille to +0.37per mille) reflected a sole Cr source, seasonality of weathering and hydrologically controlled leaching/export processes. In the NEG catchment, back-reduction of Cr(VI) to Cr(III) during riverine transport resulted in a decrease in Cr concentrations (to 10-30percent) and in an increase of d53Cr values (+0.09 to +0.42per mille for the upstream to +0.72 to +1.73per mille for the downstream). Groundwater discharge could have influenced the chemical composition of the downstream NEG runoff to some extent.
