Vanadium bioavailability in soils amended with blast furnace slag

Abstract: Blast furnace (BF) slags are commonly applied as soil amendments and in road fill material. In Sweden they are also naturally high in vanadium. The aim of this study was to assess the vanadium bioavailability in BF slags when applied to soil. Two soils were amended with up to 29 % BF slag (containing 800 mg V kg -1 ) and equilibrated outdoors for 10 months before conducting a barley shoot growth assay. Additional soil samples were spiked with dissolved vanadate(V) for which assays were conducted two weeks (fre… Show more

“…Vanadate(V) is considered the most toxic vanadium species (Martin and Kaplan, 1998;Larsson et al 2013). In three Swedish soils it was found that the soil appears to be dominated by vanadium(IV) bound in primary minerals (Larsson et al 2015a;Larsson et al 2015b); this V has probably a low bioavailability. However, when vanadium is added to soils (either as vanadium(IV) or vanadium(V) salts), it tends to accumulate as vanadate(V) sorbed to iron and aluminium hydrous oxides, except in acid organic soils, in which vanadyl(IV) complexed to organic matter will predominate (Larsson et al 2015a, Larsson et al 2015b).…”

“…While WHAM7 does not model these elements, literature indicated that they too are likely sequestered by organic molecules (Bowell, 1994;Kautenburger et al, 2017;Larsson et al, 2015;Lu et al, 1998;Maji et al, 2008;Wang et al, 2015;Wichard et al, 2009;Xu et al, 1991). Arsenic and Mo typically prefer oxyhydroxides, such as goethite and hematite, however, in competitive environments with humic substances, they preferentially sorb to organics (Bowell, 1994;Wichard et al, 2009;Xu et al, 1991).…”
