The marine biogeochemistry of chromium isotopes
In the ocean, chromium (Cr) is a redox-sensitive trace metal. The reduction of Cr(VI) to Cr(III) occurs in oxygen deficient zones (ODZs), and Cr reduction in general has been identified as a significant Cr isotope fractionation mechanism. This thesis presents the first Cr isotope variations (d53Cr) …

In the ocean, chromium (Cr) is a redox-sensitive trace metal. The reduction of Cr(VI) to Cr(III) occurs in oxygen deficient zones (ODZs), and Cr reduction in general has been identified as a significant Cr isotope fractionation mechanism. This thesis presents the first Cr isotope variations (653 …

Isotopic fractionation of chromium and uranium during abiotic and microbial Cr(VI) reduction and microbial U(VI) reduction
Reduction of hexavalent chromium (Cr(VI)) influences the chemical behavior of Cr in a variety of geochemical settings such as ancient and modern oceans, lakes and groundwater and surface water systems. Cr(VI) reduction immobilizes the toxic form of Cr to less toxic and insoluble Cr(III). Several …
