TLDR
The 2011 WHO Guidelines for Drinking-Water Quality (fourth edition) advised a health-based value of 70μg/L for Mo but this is no longer promulgated as a formal guideline value as WHO consider such concentrations to be rarely found in drinking water as discussed by the authors.About:

Molybdenum-Quinone-Catalyzed Deoxygenative Coupling of Aromatic Carbonyl Compounds.
TL;DR: In the presence of triphenylphosphine as a mild reductant, the use of catalytic amounts of Mo(CO)6 and an ortho-quinone ligand enables the intermolecular reductive coupling of aromatic aldehydes and the intramolecular coupling of aromas to produce functionalized alkenes.
Journal ArticleDOI
Spatial-temporal analysis and background value determination of molybdenum concentration in basins with high molybdenum geochemical background - A case study of the upper Yi River basin.
TL;DR: In this article, a linear fitting on the soil samples and water samples collected from the natural areas and areas affected by human mining activities, and established a leaching model was used to compare the leaching capability of molybdenum in the soil of different areas.
Journal ArticleDOI
Immobilization of molybdenum by alternative cementitious binders and synthetic C-S-H: An experimental and numerical study.
TL;DR: This paper studies the immobilization of Mo by three cementitious binders and suggests that powellite is less stable in cementitious environments than would be expected from thermodynamic databases.

The role of pedogenesis and natural fertiliser as vectors for essential metal content in agricultural topsoils, Central India
TL;DR: In this article, a geochemical survey across a road traverse of 600 km, encompassing an area of c. 15,000 km2, was conducted in Central India to evaluate reported essential metal deficiency in key agricultural topsoils.

Determination of Trace Metal (Mn, Fe, Ni, Cu, Zn, Co, Cd and Pb) Concentrations in Seawater Using Single Quadrupole ICP-MS: A Comparison between Offline and Online Preconcentration Setups
TL;DR: In this article, a robust method for measuring dissolved metals from seawater accurately and precisely using a seaFAST and quadrupole Inductively Coupled Plasma Mass Spectrometer (ICPMS), employed in both offline (2016-2018) and online (2020-2021) setups.

A review of the source, behaviour and distribution of arsenic in natural waters
TL;DR: The scale of the problem in terms of population exposed to high As concentrations is greatest in the Bengal Basin with more than 40 million people drinking water containing ‘excessive’ As as mentioned in this paper.
Journal ArticleDOI
The composition of the continental crust
TL;DR: In this paper, a new calculation of the crustal composition is based on the proportions of upper crust (UC) to felsic lower crust (FLC) to mafic lower-crust (MLC) of about 1.6:0.4.

Abundance of chemical elements in the continental crust: a new table
TL;DR: In this article, a table of element abundances in the continental crust, calculated on the basis of a 1:1 mixture of granite and basalt abundances, is presented.
