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:

Impact of surface modification of chabazite on the sorption of iodine and molybdenum radioisotopes from liquid phase
S.S. Metwally,M.F. Attallah +1 more
TL;DR: In this paper, a modification of chabazite using N-methylene aniline to produce Ch-NMA composite for the sorption of 131I and 99Mo, as anionic species of radionuclides, from the liquid phase.
Journal ArticleDOI
Iron- and aluminium-induced depletion of molybdenum in acidic environments impedes the nitrogen cycle.

TL;DR: It is demonstrated that Fe and Al mineral formation that occurs as the pH of acidic synthetic groundwater is increased, decreases soluble Mo to low picomolar concentrations, a process proposed to mimic environmental diffusion of acidic contaminated groundwater.

TL;DR: In this article, N2fixing trees in secondary Neotropical forests triggered twofold higher in situ weathering of fresh primary silicates compared to non-N2-fixing tree and induced locally enhanced nutrient cycling by the soil microbiome community.

Mobilization of Metal(oid) Oxyanions through Circumneutral Mine Waste-Rock Drainage.
Bas Vriens,E.K. Skierszkan,Melanie St-Arnault,Kristin Salzsauler,Celedonio Aranda,K. Ulrich Mayer,Roger Beckie +6 more
TL;DR: It is demonstrated that oxyanion concentrations of environmental concern may be conveyed by neutral- to alkaline-pH waste-rock drainage and should be a focus of mine wastewater monitoring programs.
Journal ArticleDOI
A review of the current environmental status and human health implications of one of the most polluted rivers of Mexico: The Atoyac River, Puebla
Abrahan Mora,Maritza García-Gamboa,Mari Sol Sánchez-Luna,Lilian Gloria-García,Pabel Cervantes-Avilés,Jürgen Mahlknecht +5 more
TL;DR: For more than 4 decades, the Atoyac River in central Mexico has been subjected to anthropogenic stresses driven by the urban and industrial wastewater discharges, as well as leachates coming from intensive peri-urban agricultural practices as mentioned in this paper.

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.

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.
