“…Vanadium contamination of the geological environment is widespread globally. Table S1 (Supporting Information (SI)) lists vanadium distributions in solid matrices including soil and sediment (Nedrich et al, ; Shaheen & Rinklebe, ; Timofeeva et al, ). Surface water in Panzhihua region, Southwestern China, also contains high concentrations of vanadium, ranging from 0.076 to 0.285 mg/L in Jinsha River near a tailing impoundment, exceeding the recommended limit of 0.05 mg/L for drinking water sources based on standards of China (Wang et al, ).…”

Vanadium mining activities can cause contamination of the surrounding geological environment. Vanadium may exist in multiple matrices due to its migration and transformation, forming interactive relationships; however, the connection between vanadium distributions in multiple matrices and microbial community responses remains largely unknown. Vanadium is a redox‐sensitive metal that can be microbiologically reduced and immobilized. To date, bioremediation of vanadium‐contaminated environments by indigenous microorganisms has rarely been evaluated. This paper reports a systematic investigation into vanadium distributions and microbial communities in soils, water, and sediment from Panzhihua, China. Large vanadium contents of 1130.1 ± 9.8 mg/kg and 0.13 ± 0.02 mg/L were found in surface soil and groundwater. Vanadium in surface water tended to precipitate. Microbial communities isolated from similar environments were alike due to similarity in matrix chemistry whereas communities were distinct when compared to different matrices, with lower richness and diversity in groundwater. Proteobacteria was distributed widely and dominated microbial communities within groundwater. Redundancy analysis shows that vanadium and nutrients significantly affected metal‐tolerant bacteria. Long‐term cultivation (240 days) suggests the possibility of vanadium bioremediation by indigenous microorganisms, within acid‐soluble fraction. This active fraction can potentially release mobile vanadium with shifted redox conditions. Vanadium (V) was bio‐reduced to less toxic, mobile vanadium (IV) primarily by enriched Bacillus and Thauera. This study reveals the biogeochemical fate of vanadium in regional geological environments and suggests a bioremediation pathway via native vanadium‐reducing microbes.

“…The positive correlation of the Sr and V ions bound to the WSC with the acidic fractions of the SOC showed that the fixation of the Sr and V ions by the soil organic substances led to the formation of unstable complexes, without a significant Sr and V retention. The highly positive correlation between the Sr and V contents and the soil compounds enriched by the Mn, Si, and Ca ions is related to the presence of the Sr and V ions in the soil minerals (Timofeeva et al 2018). The Sr and V ion values showed a negative correlation with the clay and Fe ion contents.…”

“…The total macro element contents of the soils were determined via energy dispersive X-ray fluorescence spectroscopy (EDX), using a Shimadzu EDX-800HS-P instrument as described by Timofeeva et al (2018). For the measurement of the total trace element contents, the soil samples were completely dissolved in HF and HNO 3 based on Pansu and Gautheyrou (2006).…”

We quantified the soluble fractions of the soil organic carbon (SOC) concentrations and the total and water-soluble trace elements in soils contaminated by household waste and remediated via the addition of green manure over 13 years and identified the main factors controlling the vertical distribution and accumulation of the trace elements. Green manure favoured the active formation of soil organic matter. The SOC of the examined soils was characterised by the active stabilisation by mineral soil compounds, but by a low degree of humification. The soils showed increased concentrations of Cr and Ni ions. The SOC and different soil compounds enriched by Si, Ca, and Mn ions were the important determinant for the distribution of Sr, V and Cu ions, as well as for the distribution of Pb and Cr ions bound to the water-soluble components of the soils. The low degree of SOC humification may be one of the main reasons of the high concentrations of Cu and Pb ions in the composition of the water-soluble soil compounds. The nickel ions were mainly associated with compounds enriched by the Al and Fe ions. The extremely high percentage concentration of the Ni ions in the water-soluble components of the soils may be result of the absence of the Ni ions adsorption by humic substances.

“…As shown in Table S3, metal levels in urban soils, suburban soils, and peri-urban soils were different, which might be ascribed to the effect of urbanization and land uses (agricultural, industrial, mining, residential, recreational, and commercial areas). It is commonly believed that anthropogenic sources for these metals covered industrial activities (mining, coal combustion, smelting, iron and steel production, and metal processing), traffic sources (combustion of fossil fuels, wear and tear of vehicle components, and loss by friction), agricultural activities (herbicides/pesticides, wood preservations, and fertilizers), oil-and coal-related activities (combustion of fuel-oil), construction sources, and urban wastes (Xia et al, 2011;Poňavič, Wittlingerová, Čoupek, & Buda, 2018;Wang, Zeng, et al 2018;Zhang, Lu, Shi, & Pan, 2018;Timofeeva, Kosheleva, Semal, & Burdukovskii, 2018). In this study, most of the metal concentrations were higher inside of the campus than those from outside, likely due to anthropogenic effects such as urbanization.…”

Metal status in soils within a developing education park: Potential risk of land development

Many countries have developed university/college towns with specific characteristics (temporal, spatial, structural, and functional aspects). During the land development, there were obvious changes in soil metal levels and distribution patterns attributed to anthropogenic activities, thus having induced comparable results in university/college towns due to similar anthropogenic activities. Until now, specific studies on the metal status in university/college towns, especially the variation inside and outside of a campus were rarely involved. Herin we report on 109 soil samples around a new campus within a developing education park, in which the levels, spatial distributions, and possible sources of (alkali, alkaline-earth, transition, and main group) metals and metalloids (Cd, Cr, As, Pb, Zn, Cu, Mn, Ba, Ni, Ti, Be, Bi, Sb, Sn, Co, V, and Zr) were systematically investigated. The Nemerow pollution indexes, spatial analysis, principal components analysis, and cluster analysis were calculated and analyzed. The results showed that the level of most metals within the campus with different functional areas (college, activity, and greening areas) was 1-1.3-times as much as that outside in four directions and had greater variations. Moreover, the level of most metals was 1-1.5-times as much as their background value and they distributed in the areas under specific developments and might mainly be attributed to anthropogenic sources. These findings provide the knowledge about effects of land development and anthropogenic activities on soil metal status that could be used by university/college towns in the similar context around the world.
