Chromium isotopes and the fate of hexavalent chromium in the environment

Research output: Contribution to journalArticlepeer-review


Measurements of chromium (Cr) stable-isotope fractionation in laboratory experiments and natural waters show that lighter isotopes reacted preferentially during CR(VI) reduction by magnetite and sediments. The 53Cr/52Cr ratio of the product was 3.4 ± 0.1 per mil less than that of the reactant.53Cr/52Cr shifts in water samples indicate the extent of reduction, a critical process that renders toxic CR(VI) in the environment immobile and less toxic.
