“…Lung disease is common among workers engaged in vanadium production (Teng et al, ). Vanadium widely exists in the Earth's crust alongside minerals, crude oil, and coal (Huang et al, ). Global and European vanadium concentrations in soil typically range between 90 and 60 mg/kg (Yang, Tang, et al, ).…”

Vanadium mining activities can cause contamination of the surrounding geological environment. Vanadium may exist in multiple matrices due to its migration and transformation, forming interactive relationships; however, the connection between vanadium distributions in multiple matrices and microbial community responses remains largely unknown. Vanadium is a redox‐sensitive metal that can be microbiologically reduced and immobilized. To date, bioremediation of vanadium‐contaminated environments by indigenous microorganisms has rarely been evaluated. This paper reports a systematic investigation into vanadium distributions and microbial communities in soils, water, and sediment from Panzhihua, China. Large vanadium contents of 1130.1 ± 9.8 mg/kg and 0.13 ± 0.02 mg/L were found in surface soil and groundwater. Vanadium in surface water tended to precipitate. Microbial communities isolated from similar environments were alike due to similarity in matrix chemistry whereas communities were distinct when compared to different matrices, with lower richness and diversity in groundwater. Proteobacteria was distributed widely and dominated microbial communities within groundwater. Redundancy analysis shows that vanadium and nutrients significantly affected metal‐tolerant bacteria. Long‐term cultivation (240 days) suggests the possibility of vanadium bioremediation by indigenous microorganisms, within acid‐soluble fraction. This active fraction can potentially release mobile vanadium with shifted redox conditions. Vanadium (V) was bio‐reduced to less toxic, mobile vanadium (IV) primarily by enriched Bacillus and Thauera. This study reveals the biogeochemical fate of vanadium in regional geological environments and suggests a bioremediation pathway via native vanadium‐reducing microbes.

“…V, which can exist in three common oxidation states, is largely found as the vanadate ion (H 2 VO 4 − ) in natural oxidized waters of near-neutral pH. The dissolved concentration in river water is about 0.7 μg/L, less than half of the concentration of ∼1.8 μg/L in seawater (13).…”

“…Huang et al (13) provide a comprehensive review of the oxidation and reduction processes that transform V in Earth's surface environments, and Hope (24) quantifies the movement of V on the present-day and future Earth, based on its mobilization by human activities. In this paper, we provide an updated, quantitative summary of the global biogeochemical cycle of V, including both human and natural fluxes.…”

Synthesizing published data, we provide a quantitative summary of the global biogeochemical cycle of vanadium (V), including both human-derived and natural fluxes. Through mining of V ores (130 × 10 9 g V/y) and extraction and combustion of fossil fuels (600 × 10 9 g V/y), humans are the predominant force in the geochemical cycle of V at Earth's surface. Human emissions of V to the atmosphere are now likely to exceed background emissions by as much as a factor of 1.7, and, presumably, we have altered the deposition of V from the atmosphere by a similar amount. Excessive V in air and water has potential, but poorly documented, consequences for human health. Much of the atmospheric flux probably derives from emissions from the combustion of fossil fuels, but the magnitude of this flux depends on the type of fuel, with relatively low emissions from coal and higher contributions from heavy crude oils, tar sands bitumen, and petroleum coke. Increasing interest in petroleum derived from unconventional deposits is likely to lead to greater emissions of V to the atmosphere in the near future. Our analysis further suggests that the flux of V in rivers has been incremented by about 15% from human activities. Overall, the budget of dissolved V in the oceans is remarkably well balanced-with about 40 × 10 9 g V/y to 50 × 10 9 g V/y inputs and outputs, and a mean residence time for dissolved V in seawater of about 130,000 y with respect to inputs from rivers.vanadium | petroleum | geochemical cycle | aerosols | rock weathering V anadium (V) occurs in a wide range of earth materials and is a relatively abundant trace metal, with an average concentration in the upper continental crust (97 mg/kg) more than double those of nickel (Ni) and copper (Cu) (1). In modern society, the majority of V is used to improve the strength and corrosion resistance of steel; it is also of increasing strategic and technological interest as a specialty metal in electronics and batteries. V is an essential trace element in prokaryotic biochemistry, where it is found as an alternative to molybdenum in the molecular structure of nitrogenase, the enzyme of N fixation (2-4). It also appears in the structure of enzymes in the marine algae responsible for the formation of bromoform (5) and methyl bromide (6), which contributes to the depletion of stratospheric ozone. Whether V is an essential trace element in higher plants and animals is unknown (7), with some evidence favoring an essential role in at least some higher organisms (e.g., refs. 8 and 9). Higher plants accumulate about 1 mg/kg in their tissues (10).The mean concentration of V in the continental crust is about 97 mg/kg (1, 11), and ∼20 × 10 9 g V/y enters biogeochemical cycles at Earth's surface through chemical weathering (12). V, which can exist in three common oxidation states, is largely found as the vanadate ion (H 2 VO 4 − ) in natural oxidized waters of near-neutral pH. The dissolved concentration in river water is about 0.7 μg/L, less than half of the concentration of ∼1.8 μg/L in seawa...

“…The cements are believed to have formed from meteoric waters, because marine carbonate cements in the lower part of the sedimentary succession are composed of ankerite or siderite, which is consistent with marine fluids enriched in ferrous iron from the Gunflint Sea. The meteoric cements preserve a negative inferred Ce anomaly and have conspicuously high concentrations of V, U, and Cr, metals that form soluble oxyanions in their higher oxidation states, although V may be made soluble by organic complexation as well (Huang, Huang, Evans, & Glasauer, ). The δ 53 Cr values are much higher than those reported by Frei et al.…”

Cr isotopic insights into ca. 1.9 Ga oxidative weathering of the continents using the Beaverlodge Lake paleosol, Northwest Territories, Canada

et al. 2019

The ca. 1.9 Ga Beaverlodge Lake paleosol was studied using redox‐sensitive Cr isotopes in order to determine the isotopic response to paleoweathering of a rhyodacite parent rock 500 million years after the Great Oxidation Event. Redox reactions occurring in modern weathering environments produce Cr(VI) that is enriched in heavy Cr isotopes compared to the igneous inventory. Cr(VI) species are soluble and easily leached from soils into streams and rivers, thus, leaving particle‐reactive and isotopically light Cr(III) species to build up in soils. The Beaverlodge Lake paleosol and two other published weathering profiles of similar age, the Flin Flon and Schreiber Beach paleosols, are not as isotopically light as modern soils, indicating that rivers were not as isotopically heavy at that time. Considering that the global average δ53Cr value for the oxidative weathering flux of Cr to the oceans today is just 0.27 ± 0.30‰ (1σ) based on a steady‐state analysis of the modern ocean Cr cycle, the oxidative weathering flux of Cr to the oceans at ca. 1.9 Ga would have likely been shifted to lower δ53Cr values, and possibly lower than the igneous inventory (–0.12 ± 0.10‰, 2σ). Mn oxides are the main oxidant of Cr(III) in modern soils, but there is no evidence that they formed in the studied paleosols. Cr(VI) may have formed by direct oxidation of Cr(III) using molecular oxygen or H2O2, but neither pathway is as efficient as Mn oxides for producing Cr(VI). The picture that emerges from this and other studies of Cr isotope variation in ca. 1.9 Ga paleosols is of atmospheric oxygen concentrations that are high enough to oxidize iron, but too low to oxidize Mn, resulting in low Cr(VI) inventories in Earth surface environments.
