Tungsten (W) is a rare element and present in the earth's crust mainly as iron, aluminium,
and calcium minerals including wolframite and scheelite. This review aims to offer an …

Groundwater samples were collected along flow paths within the Carrizo Sand aquifer
(southeastern Texas) and the Aquia aquifer (coastal Maryland) for analysis of dissolved …

Tungsten is both naturally occurring and an anthropogenically released contaminant metal
in soils, sediments and water systems that typically exits as the soluble tungstate oxyanions …

Considerable questions persist regarding tungsten geochemistry in natural systems,
including which forms of tungsten are found in soils and how adsorption regulates dissolved …

Tungsten is a widely used transition metal that has not been thoroughly investigated with
regards to its ecotoxicological effects. Tungsten anions polymerize in environmental systems …

Tungsten (W) is expected to adsorb to soil minerals, but does not appear to do so in many
environments. To explain this behavior, adsorption experiments were performed over a …

Using UV/VIS spectrophotometry the equilibrium constants for the formation of
monothiotungstate, WO 3 S 2−(WO 4 2-+ H 2 S↔ WO 3 S 2-+ H 2 O; log K 01= 3.08±0.11) …

Tungsten is a valuable industrial metal with limited effective substitutes for its many industrial
uses. Tungsten is classified as a critical mineral by many countries, including Canada and …

Tungsten (W) is a contaminant with health implications whose environmental behaviors are
not understood well. Sorption to mineral surfaces is one of the primary processes controlling …
