“…Increasing adsorption of V with decreasing pH has been reported previously on ferrihydrite surfaces in aqueous solutions (Larsson et al., 2017). The higher mobility of V in alkaline soils than in acidic soils was also reported by Shaheen and Rinklebe (2018), where soil organic matter, total sulfur, and carbonates correlated with V. Maximum adsorption capacity of V(V) onto silica was reported at the pH range between 3 and 5 (Gan et al., 2020). Creating more negative charges on organic and inorganic soil colloids at high pH facilitates the release of negatively charged vanadates to soil solution and would have been another reason to have higher V in pore water in zeolite‐amended treatments than other treatments.…”

Addition of manganese(IV) oxides (MnO2) and zeolite can affect the mobility of As and V in soils due to geochemical changes that have not been studied well in calcareous, flooded soils. This study evaluated the mobility of As and V in flooded soils surface‐amended with MnO2 or zeolite. A simulated summer flooding study was conducted for 8 weeks using intact soil columns from four calcareous soils. Redox potential was measured in soils, whereas pH, major cations, and As and V concentrations were measured biweekly in pore water and floodwater. Aqueous As and V species were modeled at 0, 4, and 8 weeks after flooding (WAF) using Visual MINTEQ modeling software with input parameters of redox potential, temperature, pH, total alkalinity, and concentrations of major cations and anions. Aqueous As concentrations were below the critical thresholds (<100 μg L−1), whereas aqueous V concentrations exceeded the threshold for sensitive aquatic species (2–80 μg L−1). MnO2‐amended soils were reduced to sub‐oxic levels, whereas zeolite‐amended and unamended soils were reduced to anoxic levels by 8 WAF. MnO2 decreased As and V mobilities, whereas zeolite had no effect on As but increased V mobility, compared to unamended soils. Arsenic mobility increased under anoxic conditions, and V mobility increased under oxic and alkaline pH conditions. Conversion of As(V) to As(III) and V(V) to V(IV) was regulated by MnO2 in flooded soils. MnO2 can be used as an amendment in immobilizing As and V, whereas the use of zeolite in flooded calcareous soils should be done cautiously.

“…Generally, Vanadium can exist in several valence states (− I, 0, + II, + III, + IV, and + V), and pentavalent vanadium V(V) is the most toxic and mobile form (Imtiaz et al 2015a). The toxicity of vanadium is considered comparable to that of mercury, lead and arsenic (Lazaridis et al 2003;Xu et al 2019;Gan et al 2020). For plant, vanadium at low level is a valuable element with the potential to be used in biostimulation and/or biofortification in plant growth and development (García-Jiménez et al 2018).…”

Seed germination is the critical initial phase in the life cycle of plant and it is affected by various exogenous factors, including heavy metals. Seed germination and subsequent seedling growth of alfalfa (Medicago sativa L.) incubated in glass Petri dish in presence of elevated concentrations of pentavalent vanadium V(V) solution (0, 0.1, 0.5, 2, 4, 10, 50 mg L −1 V, supplied as NaVO 3 •2H 2 O) were evaluated. Results showed that vanadium did not (P > 0.05) affect seed germination, final survival rate, and seedling height of alfalfa when exogenously treated dosages were ≤ 10 mg L −1 V, whereas the root vitality and root elongation were distinctly inhibited at ≥ 0.5 mg L −1 V treatments. A progressively deepened testa color at increasing vanadium concentrations during germination and an apparent modified structure of the seed coat at 50 mg L −1 V compared to control in alfalfa were noted. Alfalfa seeds showed rapid and almost synchronous radicle emergence, independently of the vanadium concentration in the medium. The accumulation of vanadium in testa is beneficial to alleviate its toxicity to the seed germination of alfalfa. Leaf proline content was dramatically increased at ≥ 0.5 mg L −1 V treatments compared with the control. Emerged seedlings displayed enough vigor and health to potentially colonize in the vanadium-contained matrix. Thus, alfalfa represents a good candidate for phytoremediation approach aimed at decontaminating environments when vanadium concentrations are within the determined thresholds.

“…Riparian soil and sediment both played a role as a sink of Zn, which can desorb from solid matter to water. Soil represents a large sink of V and always strongly retains V 52 . Therefore, we found that riparian soil had a high concentration of V, and we observed a significant positive relation between the soil V and water V ( r 2 = 0.94, p < − 0.05).…”

Risk assessment and source apportionment of trace elements in multiple compartments in the lower reach of the Jinsha River, China

Studies on trace element (TE) pollution in abiotic matrices have typically focused on water, sediment, and soil, either separately or in pairs. The importance of multi-media connectivity has been ignored. This study analyzed the concentrations of 6 TEs in three connected environmental compartments of a 28-km section of the lower reach of the Jinsha River. The ecological risk posed by TEs was higher in soil than in sediment. The contribution of exposure pathways to human health risk were ranked as ingestion > dermal contact > inhalation. An improved regional environmental risk index (RERI) method was then developed to evaluate the comprehensive risk on both ecology and human health caused by TEs. The average RERI value was generally higher in the wet season (0.42) than in the dry (0.41) and dry-to-wet transition seasons (0.08) because of the combined effects of the high TE concentrations in riparian soil and the long exposure time. Source apportionment indicated that industrial activities, weathering of parent rock, and agricultural activities were possible sources of TEs in this region. The methods and results of this study could inform local environmental management and provide references for similar cases wherein multiple compartments of river systems should be considered.
