Manganese (Mn) oxide formation in modern day environmental systems is likely often mediated via microbial Mn(II) oxidation. Such biogenic Mn oxides are typically poorly crystalline Mn(III/IV) (hydr)oxide phyllomanganate minerals with large sorption capacities for trace metals (e.g…
Remediating manganese (Mn) from coal mine drainage (CMD) can be challenging, largely due to slow kinetics of aqueous Mn(II) oxidative precipitation to solid Mn(IV/III) (oxyhydr)oxide minerals. CMD passive bioremediation sites utilize liner rocks (e.g…
Manganese (Mn), a micronutrient but also a contaminant at elevated concentrations, causes a wide variety of human health effects at high concentrations as well as lower level chronic exposures of just 100 ppb Mn…
