TL;DR: Long-term increased lithium exposure in drinking water may be associated with a lower incidence of dementia in a nonlinear way; however, confounding from other factors associated with municipality of residence cannot be excluded.

TL;DR: In this article, the authors used Mossbauer spectroscopy to obtain the domain of existence of a green rust with an ordered upper bound of [ 0.25, 0.33 ] for x = { [ Fe III ] / [ Fe total ] } with ordered upper limit [ Fe II 4 Fe III 2 ( OH ) 12 ] 2 + ⋅ [ CO 3 ∆ ∼ 3 H 2 O ] 2 −.

TL;DR: The ability of microorganisms to reduce structural Fe in minerals has become recognized as an important mechanism in the oxidation of pollutants in soils and sediments as discussed by the authors, where the authors used a combination of Pseudomonas bacteria strains for reducing structural Fe(III) to Fe(II) in smectites.

TL;DR: This work presents a framework for assessing nitrate reduction in the subsurface and for assessing at which spatial scales modelling tools have predictive capabilities and the flow paths within the catchment are simulated.

TL;DR: In this paper, the authors focused on NO3- re-duction in clayey sediments and found a significant correlation between NO 3 and the amount of reduced Fe 2§ in the suboxic (oxic-II) zone, indicating that primary structural Fe 2+ in the clay minerals is the reductant in a NO 3 reduction process.
