“…S2 † ). The results were similar to the findings of the dry biomass in Chenopodium quinoa , 48 Sophora alopecuroides , 2 and Festuca arundinacea 6 which decreased at a higher Pb stress. However, compared to the other species, the TI values were lower, especially under a higher Pb concentration.…”

“…With the rapid development and modernization of industry and population growth, serious soil contamination with heavy metals has increased rapidly, becoming a global problem. 1,2 Heavy metals cannot be degraded, which makes these toxic elements persistent in the environment and more difficult to control. 3,4 Lead (Pb), which is considered the second most toxic contaminant aer arsenic, 5 exists widely in the ecosystems.…”

“…They can deteriorate soil quality, reduce food safety, and threaten human health (Li et al 2014 ). Moreover, these metals are not degraded by chemical or biological methods and are persistent in soil (Cheraghi-Aliakbari et al 2020 ). Cadmium (Cd), one of the most toxic heavy metals, and nonessential for humans and animals, is widely present in soil due to anthropogenic activities such as smelting, mining and battery disposal (DalCorso et al 2019 ; Mitra et al 2018 ).…”

Concentrations of heavy metals continue to increase in soil environments as a result of both anthropogenic activities and natural processes. Cadmium (Cd) is one of the most toxic heavy metals and poses health risks to both humans and the ecosystem. Herein, we explore the impacts of Cd on a soil–plant system composed of oilseed rapes (Brassica napus and Brassica juncea) and bacteria. The results showed that Cd accumulation within tissues of two species of oilseed rapes enhanced with increasing concentrations of Cd in soils, and Cd treatment decreased their chlorophyll content and suppressed rapeseeds growth. Meanwhile, Cd stress induced the changes of antioxidative enzymes activities of both B. napus and B. juncea. Response to Cd of bacterial community was similar in soil-two species of oilseed rapes system. The impact of Cd on the bacterial communities of soils was greater than bacterial communities of plants (phyllosphere and endophyte). The α-diversity of bacterial community in soils declined significantly under higher Cd concentration (30 mg/kg). In addition, soil bacterial communities composition and structure were altered in the presence of higher Cd concentration. Meanwhile, the bacterial communities of bulk soils were significantly correlated with Cd, while the variation of rhizosphere soils bacterial communities were markedly correlated with Cd and other environmental factors of both soils and plants. These results suggested that Cd could affect both the growth of plants and the indigenous bacterial community in soil–plant system, which might further change ecosystem functions in soils.

“…Phytoremediation in PTE-contaminated soils has been widely used because of its low cost and ecofriendliness compared with traditional physical or chemical approaches (Ju et al, 2020;Kanwar et al, 2020). Phytoremediation, including phytoextraction and phytostabilisation, has shown satisfactory results, and relies on the natural capacity of plants to remove or stabilise metal pollutants in contaminated sites (Cheraghi-Aliakbari et al, 2020;Egendorf et al, 2020). The uptake, translocation, and accumulation of pollutants in soil-plant systems mainly depend on the plant species (Jiang et al, 2018).…”

Though gold mines provide signi cant economic bene ts to local governments, mining causes soil pollution by potentially toxic trace elements (PTEs) in mining areas, especially in the Qinghai-Tibet Plateau. Screening of native plant species from mining areas is now an effective, inexpensive, and ecofriendly method for the remediation of PTEs in situ. In the present study, we conducted experiments to assess the accumulation of As, Cd, Pb, and Zn in 12 native plant species growing on a typical gold mining area in Qinghai-Tibet Plateau. Our results showed that rhizosphere soils have high soil organic matter content, high levels of As, and moderate levels of Cd. G. pylzowianum accumulated relatively higher As in its shoots and exhibited TF higher than 1 for As (4.65), Cd (1.87), and Pb (1.36). P. saundersiana had BCF-S higher than 1 for Cd (4.52) and Pb (1.70), whereas its TF was higher than 1 for As, Cd, Pb, and Zn. These plant species also exhibit strong tolerance to these PTEs. Furthermore, E. nutans accumulated low levels of As, Cd, Pb, and Zn in their shoots and exhibited TF values lower than 1 for the four PTEs. Therefore, G. pylzowianum could be used for the in situ phytoextraction of As, and P. saundersiana can be used as an effective plant for Cd and Pb phytoextraction. E. nutans is better suited for the phytostabilisation of multiple PTEs. Our study is of signi cant importance for introducing native plant species to remediate PTE-contaminated soils, particularly As and Cd, and has a good potential for developing PTE phytoremediation strategies at mining sites. HighlightsAs was the prime pollutant in soils surrounding the gold mine.Phytoremediation of PTEs in 12 native plants was examined at a gold mining site. P. saundersiana had TF higher than 1 for all PTEs.
