TL;DR:
The redox transformation of mobile Cr(vi) to less soluble Cr(iii) species observed in this study implies that biogenic Fe (oxyhydr)oxides in soils and natural waters may naturally attenuate Cr(ii) concentrations through sorption and reduction processes, thus limiting its transport to downstream environments.

Biogenic iron (oxyhydr)oxides adsorb dissolved Cr(vi), as well as promote its reduction to less mobile and toxic Cr(iii)viaa Fe(ii) mediated process.
