Microbial sulfidogenesis of arsenic in naturally contaminated wetland soil

Microbial sulfidogenesis plays a potentially important role in As biogeochemistry within wetland soils, sediments, and aquifers. This study investigated the effects of microbial sulfidogenesis on As mineralogy in the As-enriched wetland soil found at the natural geochemical anomaly of the Smolotely-Líšnice (Czech Republic) historical gold district. The distribution and speciation of As as a function of soil depth, and the metabolic properties of...
