Introduction: Rio Tinto area is considered a referent as an extremophilic scenery of iron rich and acidic water conditions for life [1]. Physic-chemical equilibriums taking place along of its watercourse during a year produce a repertory of mineral species related with the main chemical species in solution (sulphates and iron). Raman spectroscopy is a powerful technique that allows studying the...

For the molybdoenzymes synthesis as the nitrogenase, the molybdenum, in its most stable form, the molybdate, must be transported inside the cell. In Bradyrhizobium japonicum, the modABC genes code for a high-affinity ABC-type molybdate transporter. This work allowed to study the effect of inoculation of soybean plants with strains affected in the molybdate transport. modA and modB mutants, unab...

I did not intend to revisit the discussion of the publication of Brandolini et al. on Ca urinary excretion attributed to the sulfate content of water but in their answers to my comments, they said that ‘I accept their experimental results’ and that ‘I do not contest the difference in calciuria between milk and sulfate-rich water’. I never wrote that I agree with their results and even more with...

Studies comparing the absorption and retention of various forms of trace minerals in horses have yielded mixed results. The objective of this study was to compare Cu and Zn absorption and retention in exercising horses where the mineral was supplemented in the sulfate or organic chelate form. Nine mature horses were used in a modified switchback design experiment consisting of seven 28-d period...

Abstract This paper presents the results of wastewater treatment at a mining enterprise developing complex ore deposit in Murmansk region, Russia. The main pollutants are sulfate, manganese, and strontium. For this treatment, two-stage scheme was proposed tested using two sorbents (at pH 6): an aminated peat biosorbent to remove sulfate commercial sorbent based on mineral brucite metals. Optima...

High-resolution mapping by visible and near-infrared orbital spectrometers has revealed a diversity of hydrated mineral deposits on the surface of Mars. Quantitative analysis of mineral abundances within these deposits has the potential to distinguish depositional and diagenetic processes. Such analysis can also provide important constraints on the nature of putative global and local-scale mine...

The “Software Package for Aerosol Size Distribution” is a novel graphical user interface application software used for the study of atmospheric aerosol size distribution from various aerosol models (Continental clean, Continental average, Continental polluted, Urban, Desert, Maritime clean, Maritime polluted, Maritime tropical, Arctic, Antarctic) and/or with different aerosol components (insolu...

Gypsum is a mineral dust consisting of calcium sulfate and is commonly used in building construction. We here report the first case of an acute calcium sulfate aspiration. An accidental avalanche of fine gypsum powder covered entirely a silo worker. He aspirated a large amount of gypsum powder without loosing consciousness. At admission to the emergency department the patient was breathing spon...

We present a new low-temperature refinement of disodium zinc bis-(sulfate) tetra-hydrate {systematic name: poly[tetra-μ-aqua-di-μ-sulfato-zinc(II)disodium(I)]}, [Na(2)Zn(SO(4))(2)(H(2)O)(4)](n) or Zn astrakanite, which is an upgrade of previously reported data [Bukin & Nozik (1974 ▶). Zh. Strukt. Khim.15, 712-716]. The compound is part of an isostructural family containing the Mg (the original ...
