The work describes in situ incubation of organic matter in As-enriched wetland soils over 15 months. As and Fe were observed to precipitate as biogenic sulfides. Realgar and bonazziite were observed as the main As-bearing sulfides. Reduced exchange of solutes caused oversaturation with respect to AsS minerals.
