“…Table S2 and Table S3 show the influence of lignite addition on soil pH and soluble concentrations of nutrients. Assuming that the bioavailability of Cd, Zn, and Cu is a function of their solubility in a 0.05 M Ca(NO 3 ) 2 extractant, this observation is surprising as Zn and especially Cu are often cited to show higher affinity to organic matter than Cd . However, Cu and Zn also form complexes with dissolved organic matter, some of which may be bioavailable .…”

“…These doses were selected based on literature values for Mo requirements as well as preliminary experiments to determine observable positive effects and excessive dosing. Background concentrations of Mo in agriculture soils generally range from 0.2–5.0 mg/kg; however, in mining affected soils, the Mo level can reach up to 2903.91 mg/kg . The selected doses in the current study were in the range as moderate and excessive Mo levels, and they were also comparable with other Mo NP toxicity studies on plant species. − , Based on a related study on the dissolution and aggregation of several metal oxide NPs, including the MoO 3 NPs used in this study, we determined the concentrations for the ionic Mo treatments corresponding to the level of dissolved metal ions expected in the media, 35 and 225 mg/L Mo, to achieve a bioavailable Mo comparable to the NP treatments.…”

Metabolomics is an emerging tool to understand the potential implications of nanotechnology, particularly for agriculture. Although molybdenum (Mo) is a known plant micronutrient, little is known of its metabolic perturbations. Here, corn and wheat seedlings were exposed to MoO 3 nanoparticles (NPs) and the corresponding bioavailable Mo 6+ ion at moderate and excessive levels through root exposures. Physiologically, corn was more sensitive to Mo, which accumulated up to 3.63 times more Mo than wheat. In contrast, metabolomics indicated 21 dysregulated metabolites in corn leaves and 53 in wheat leaves. Five more metabolomic pathways were perturbed in wheat leaves compared to corn leaves. In addition to the overall metabolomics analysis, we also analyzed individual metabolite classes (e.g., amino acids, organic acids, etc.), yielding additional dysregulated metabolites in plant tissues: 7 for corn and 7 for wheat. Most of these were amino acids as well as some sugars. Additional significantly dysregulated metabolites (e.g., asparagine, fructose, reduced glutathione, mannose) were identified in both corn and wheat, due to Mo NP exposure, by employing individual metabolite group analysis. Targeted metabolite analysis of individual groups is thus important for finding additional significant metabolites. We demonstrate the value of metabolomics to study early stage plant responses to NP exposure.

“…Therefore the Mn/Fe ratio may provide an overview of the conditions under which the host minerals/rocks of Fe and Mn formed. The iron-oxide hydrates in soil and duricrusts respond in a different way when subject to leaching test with oxalic acid and dithionite solution (Scheffer and Schachtschabel, 1976;Dill, 1985). For many years, a common method of detecting and ''quantifying'' ferrihydrite in soils has been selective dissolution with 0.2 M NH 4 -oxalate at pH 3 in the dark (Schwertmann, 1964).…”
