Abstract:
... Organic matter (OM) amendments and plant colonization can accelerate mineral weathering and soil formation in metal mine tailings for ecological rehabilitation. However, the weathering effects may dissolve uranium (U)-bearing minerals (e.g., ianthinite) and increase U dissolution in porewater and seepages. The present study aimed to characterize the U solubility and distribution among different fr ...

Abstract:
... Manganese oxide minerals can become enriched in a variety of metals through adsorption and redox processes, and this forms the basis for a close geochemical relationship between Mn oxide phases and Co. Since oxalate‐producing fungi can effect geochemical transformation of Mn oxides, an understanding of the fate of Co during such processes could provide new insights on the geochemical behaviour of ...

Abstract:
... Sewage sludge that was added to sod–podzolic sandy loam soils 28 years ago determines an increased content and mobility of Zn, Cd, Cu, and Ni compounds and this is most typical for Cd and Zn. Arable soil horizons are most severely polluted, which indicates a low migration rate of heavy metal compounds. The latter are slightly removed from soils by intrasoil flow. This is determined by their chemic ...
