Abstract: Manganese is an essential trace element and it is required for many ubiquitous enzymatic reactions. While manganese deficiency rarely occurs in humans, manganese toxicity is known to occur in certain occupational settings through inhalation of manganese‐containing dust.

Manganese is a very hard, brittle metal, which is used to increase the strength of steel alloys. Absorption from the gastrointestinal tract occurs in the divalent and tetravalent forms. Permanganates, which are strong oxidizing agents, have a +7 valence. The principal organomanganese compound is the anti-knock additive, methylcyclopentadienyl manganese

Manganese Transport and the Role of Manganese in Virulence
Annual Review of Microbiology, 2006Two areas of research have recently converged to highlight important roles for Mn2+ in pathogenesis: the recognition that both bacterial Nramp homologs and members of LraI family of proteins are Mn2+ transporters. Their mutation is associated with decreased virulence of various bacterial species.

Manganese Toxicity in Barley is Controlled by Solution Manganese and Soil Manganese Speciation
Soil Science Society of America Journal, 2012It is well established that Mn toxicity to crops may occur in acid soils and under waterlogging, but there is little information on toxic thresholds in soils. This study was set-up to derive toxic thresholds for plant growth in soils and to relate toxicity of Mn to the Mn speciation in soils.

Administration of non-cholestatic doses of manganese (Mn2+) followed by injection of bilirubin (BR) results in a severe reduction in rat bile flow. Male Sprague-Dawley rats were given various doses of Mn2+ (2, 4.5, 8, and 18 mg/kg, i.v.) and killed 0.25, 1, 3, or 5 hr later.

Manganese (Mn) is an essential metal that is required as a cofactor for many enzymes and is necessary for optimal biological function. Mn is abundant in the earth's crust and is present in soil and well water. Mn is also found in industrial settings, including mining, welding, and battery manufacture.

Transition metal complexes with metal-to-ligand charge transfer (MLCT) luminescence and photoactivity typically rely on precious metals such as ruthenium or iridium. Now, two complexes of the Earth-abundant 3d manganese have displayed room-temperature MLCT luminescence in solution and a unique excited-state reactivity.
