Occurrence of Vanadium in Belgian and European Alluvial Soils

Abstract

Vanadium (V) is a naturally occurring trace element, but total concentrations in soils and sediments are also dependent on the parent material and might be influenced by anthropogenic activities (e.g., steel industry). Despite the fact that threshold values for V in soils and/or sediments exist in various European countries, in Belgium, V is not taken into account when the environmental quality of soils and sediments has to be evaluated, despite the existence of several (diffuse) sources for V. In the first part of the study, the occurrence of V alluvial soils in Belgium was compared with V concentrations in alluvial soils (floodplain soils) across Europe. By analysis of both the Belgian and European data, the relationship between physicochemical soil characteristics and total V concentrations was quantified and some areas polluted with V were detected. A regression equation, in which V concentrations in alluvial soils were expressed as a function of major element composition, was proposed for the Belgian and European data. Additionally, single extractions with CaCl2(0.01 mol L-1) and ammonium-EDTA (0.05 mol L-1) were used to estimate short- and long-term mobility of V in the alluvial soils.

Vanadium: Global (bio)geochemistry

“…In addition to the surface chemistry of the sorbent, V adsorption and desorption depend strongly on the concentration, chemical valence and chemical species (Table 11) (Peacock and Sherman, 2004;Wehrli and Stumm, 1988;Wehrli and Stumm, 1989). 5.9 c = 5-100 mg L 1 (Wang et al, 2003) Floodplain soils, Belgian Not specified ~21800-35500 -10 mM CaCl 2 extraction (Cappuyns and Salbbinck, 2012) Ferrihydrite a Not specified ~90000 (Wehrli, 1987) Insoluble peat humic acid V(IV) ~6-60 2.1 - (Szalay and Szilágyi, 1967) -: no information a: calculation infeasible at pH 4-7; b: K d from pH 3.5-5 can not be estimated, however, higher values are expected Adsorption of both V(IV) and V(V) onto metal oxide minerals has been interpreted in terms of the formation of inner-sphere bidentate complexes for the vanadyl ion, VO 2+ , and mono-dentate complexes for vanadate ions, H n VO 4 n-3 (Motschi and Rudin, 1984;Peacock and Sherman, 2004;Wehrli and Stumm, 1989). Recent work on the adsorption of V(V) ions onto goethite (Peacock and Sherman, 2004) has demonstrated the formation of two bidentate complexes, ≡Fe 2 OVO(OH) 4 + and ≡Fe 2 OVO 2 OH o ; their intrinsic formation constants were determined by batch adsorption experiments (Table 12).…”

An evaluation of inorganic toxicity reference values for use in assessing hazards to American robins (Turdus migratorius)

“…The problem comes, however, in extrapolating hazards from that very toxic, soluble compound to the hazards of V in soil in general. Other forms of V in soil are normally very sparingly available in soil (Cappuyns and Slabbinck 2012) and have been shown to be tightly bound to Fe oxides and hydroxides (Baken et al 2012).…”

Heavy Metals Content and Pollution in Tin Tailings from Singkep Island, Riau, Indonesia

“…Naturally, vanadium concentration in soils and sediment relies on the parent material and V-containing minerals. Moreover, anthropogenic activities such as using of pesticide, burning of fossil fuels, iron refining and dyeing release vanadium to the environment (Cappuyns & Slabbinck 2012;Teng et al 2011;Wright & Belitz 2010). This element mainly associated with Fe(hydro)oxides, clay minerals and organic matter.…”

“…Most of the heavy metals are brought into the human body via food and water in the diet, the air we breathe, tailing leakage and occupational exposure (Ray & Ray 2009;Teng et al 2011). Body immunotoxicity, nasal irritation, skin illness, intractable vomiting, and gastrointestinal disease are health effects of lead, chrome, vanadium, barium, and arsenic pollutions, respectively (Cappuyns & Slabbinck 2012;Llugany et al 2000;Ray & Ray 2009).…”
