Manganese behavioral effect

Only one study was located concerning behavioral effects in rodent pups following gestational exposure to airborne inorganic manganese by the dams (Lown et al. 1984). Unfortunately, this study does not provide conclusive evidence of exposure-induced behavioral effects.

The various components of the mixed precipitates that result from these interactions may subsequently or concurrently participate in the redox alterations. Often these eflFects raise the oxidation state of the manganese in the precipitate above what would be expected in a pure manganese oxide precipitated in the absence of other metal ions. Chemical thermodynamic calculations can be used to predict or explain these processes. Some effects of lead and cobalt on manganese behavior have been evaluated theoretically and experimentally. 

The studies performed over promoted manganese molybdate catalysts have shown significant changes in catalytic behavior due to presence of the promoter. The preliminary results suggest that the pronounced differences observed in selectivity and activity may be related to the effect of the promoter cations on the reactivity of the lattice oxygen and the availability of adsorbed oxygen.

Surface modification can also promote different photoluminescence responses to chemical species present in the environment. Li et al.48 synthesized water-soluble luminescent thiol-capped CdTe QDs and nanorods and investigated the effect of divalent metal ions on their photoluminescence behavior. They found that the trends of photoluminescence changes were almost similar for both, CdTe QDs and nanorods. Moreover, zinc ions enhanced the luminescence emission of the QDs while other metal ions (e.g., calcium, magnesium, manganese, nickel, and cadmium) caused luminescence quenching. 

Manganese is an essential trace element in the human diet. Overexposure, however, can lead to numerous neurological effects including hallucinations, abhorrent behavior, emotional instability, and Parkinsonism. 15 ...
