“…Further, pot experiments testing phytotoxicity by adding V 2 O 5 to an artificial soil at different nutrient levels had similar ranges of EC50 values (21-180 mg V kg -1 ) in a selection of five different plant species [24]. The wide range of threshold values becomes smaller if expressed as vanadium concentrations in soil solution [15,25].…”

“…Another set of the same soils, referred to as "aged" soils, was spiked with the above vanadate(V) concentrations and kept outside for 10 months, in the same manner as described above for the slag amended soils, before conducting the assay. A detailed description of the freshly spiked and aged soils is found in Larsson et al [15] and Baken et al [25], respectively.…”

“…Vanadium is often strongly retained in soils [10][11][12][13], and metal (hydr)oxides are important for vanadium sorption [14,15]. The retention of vanadium in soils is most pronounced around pH 4 [11].…”

“…Vanadium phytotoxicity in soil varies across soils and plant species. For example, the toxicity (EC50) of vanadate(V) to barley and tomato seedlings was tested in five different soils, and it ranged between 18 and 230 mg added V kg -1 soil [15]. Further, pot experiments testing phytotoxicity by adding V 2 O 5 to an artificial soil at different nutrient levels had similar ranges of EC50 values (21-180 mg V kg -1 ) in a selection of five different plant species [24].…”

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 (freshly spiked) and 10 months (aged) after spiking. The BF slag vanadium was dominated by vanadium(III) as shown by V K-edge XANES spectroscopy. In contrast, results obtained by HPLC-ICP-MS showed that vanadium(V), the most toxic vanadium species, was predominant in the soil solution. Barley shoot growth was not affected by the BF slag additions. This was likely due to limited dissolution of vanadium from the BF slag, preventing an increase of dissolved vanadium above toxic thresholds. The difference in vanadium bioavailability among treatments was explained by the vanadium concentration in the soil solution. It was concluded that the vanadium in BF slag is sparingly available. These findings should be of importance in environmental risk assessment.

Biological nitrogen fixation is an inherent trait exclusive to a select number of prokaryotes. Although molybdenum nitrogenase is the dominant catalyst for dinitrogen reduction, some diazotrophs also contain one or two additional types of nitrogenase that use alternative metal content as the active-site cofactor. The occurrence of alternative nitrogenases has not been well studied due to the discriminatory expression of the molybdenum nitrogenase and lack of comprehensive genomic data. This study reports on the genomic analysis of 87 unique species containing alternative nitrogenase sequences. The distribution of nitrogen-fixing genes within these species from distinct taxonomic groups shows the presence of the minimum gene set required for nitrogen fixation, including catalytic and biosynthetic enzymes of the Mo-dependent system (NifHD-KENB) and the varying occurrence of additional Nif-dedicated components. These include NifS and NifU, found primarily in aerobic species, thus suggesting that these genes are necessary to accommodate the high demand for FeÀ S clusters during aerobic nitrogen fixation.
