TL;DR: In this article, the authors investigated iron biomineralization by the anaerobic nitrate-dependent iron-oxidizing bacterium Acidovorax sp. strain BoFeN1 in the presence of dissolved Fe(II) using electron microscopy and Scanning Transmission X-ray Microscopy (STXM).

TL;DR: Evidence is provided for spatial and seasonal variations of microbial activity that influence arsenite oxidation and As immobilization in the heavily contaminated AMD from the Carnoulès mine, Gard, France and for the formation of As(III)-rich compounds in the wet season, which may help in designing efficient As-removal processes.

TL;DR: In this paper, the relationship between the crystal chemistry of arsenic and its speciation and distribution at the Earth's surface has been investigated using synchrotron-based techniques, showing the importance of As adsorption on, or coprecipitation with, hydrous ferric oxides in delaying the long-term impact of As on the biosphere.

TL;DR: In this paper, the authors investigated smelter-contaminated soils from Evin-Malmaison, Nord-Pas-de-Calais, France, and mine tailings from Leadville, Colorado, U.S.A.

TL;DR: Green rust as highly reactive iron mineral potentially plays a key role for the fate of (in)organic contaminants, such as chromium or arsenic, and nitroaromatic compounds functioning both as sorbent and reductant and may contribute to the production of extracellular Fe(III).
