“…Hosseinniaee et al 9 reported the BCF and TF of 0.42 and 0.98, and 0.23 and 2.32, respectively, for Pb and Cd in V. speciosum . In the study of Malayeri et al 65 V. speciosum had a TF of 5.91, 1.5, and 1.16 for Zn, Pb, and Cd, respectively, while BCF < 1 for all three metals. Although there is limited literature pertaining to S. arabica phytoremediation properties, it was recently found to be a suitable option for remediation of contaminated sites with TF > 1 for Pb, Zn, and Cr 9 .…”

“…The high phytostabilization potential of Stipa. barbata , another species of the genus Stipa , with BCF = 2.5 and 1.92, respectively, for Cd and Zn in cleaning soils contaminated with these metals, has been mentioned 65 . Consistent with our results, in a study investigating the lead phytoremediation ability of five bamboo species in the presence of EDTA, Jiang et al 2 found differences in metal accumulation, and Arundinaria argenteostriata and Arundinaria fortunei had higher Pb migration to shoots compared to other species.…”

This study aims to evaluate the enhancement of phytoextraction of heavy metals (Pb, Cd, and Zn) by species Marrubium cuneatum, Stipa arabica, and Verbascum speciosum, through EDTA amendment. Assisted phytoextraction pot experiments were performed at different EDTA dosages (0, 1, 3, and 5 mmol kg−1 soil). The DTPA-extractable metal content increased in the presence of EDTA, followed by their contents in the tissues of all three studied species. Resulting from oxidative stress, the activity of antioxidant enzymes such as glutathione peroxidase (GPX), superoxide dismutase (SOD), and catalase (CAT) increased when the chelating agent was added. EDTA in higher doses partially decreased chlorophyll concentration, and 5 mmol kg−1 of that reduced the biomass of the studied species. The bioconcentration factor (BCF) for Cd was notably high in all studied plants and considerably elevated for Zn and Pb with the addition of EDTA in M. cuneatum and S. arabica (BCF > 1), whilst an accumulation factor greater than one (AF > 1) was found for Cd in all species and for Pb in the case of S. arabica. In general, the results demonstrated that EDTA can be an effective amendment for phytoextraction of Cd, Zn, and Pb by M. cuneatum, V. speciosum and S. arabica in contaminated soils.

“…The plants usually involved in this process are called hyperaccumulators, as they can absorb and accumulate the metals in their upper parts [90,91]. For example, Epilobium fragilis was reported to accumulate As from contaminated soil [92]. Also, in a study using native plants, Yildirim and Sasmaz [90] observed that Anchusa arvensis, Phlomis sp., Glaucium flavum, and Verbascum thapsus demonstrated the capacity of cleaning and remediating soil affected by As pollution.…”

The distribution of arsenic continues due to natural and anthropogenic activities, with varying degrees of impact on plants, animals, and the entire ecosystem. Interactions between iron (Fe) oxides, bacteria, and arsenic are significantly linked to changes in the mobility, toxicity, and availability of arsenic species in aquatic and terrestrial habitats. As a result of these changes, toxic As species become available, posing a range of threats to the entire ecosystem. This review elaborates on arsenic toxicity, the mechanisms of its bioavailability, and selected remediation strategies. The article further describes how the detoxification and methylation mechanisms used by Shewanella species could serve as a potential tool for decreasing phytoavailable As and lessening its contamination in the environment. If taken into account, this approach will provide a globally sustainable and cost-effective strategy for As remediation and more information to the literature on the unique role of this bacterial species in As remediation as opposed to conventional perception of its role as a mobiliser of As.

“…Heavy metal pollution is generally considered to result from anthropogenic activities, such as mining, mineral fertilizers, vehicle exhaust, and other industrial activities [2,3]. Industrial activities are regarded as the principal contributor for heavy metal pollution [4]. With the rapid industrialization and urbanization of China over the last decades, various industrial activities have contributed a large amount of heavy metals to the soil, directly and indirectly [5].…”

Various industrial activities contribute heavy metals to terrestrial ecosystems. In order to evaluate the soil quality of industrial areas and to identify the potential phytoremediator from the native plant species, we collected 45 surface soil samples and 21 plant species in a typical industrial area of northwestern China. The results showed that the average values of the Cd, Cr, As, Pb, Cu, and Zn in the soils were 36.91, 1.67, 7.20, 1.38, 1.27, and 6.66 times, respectively, compared with the corresponding background values. The average single factor pollution index for heavy metals decreased in the order of Cd > As > Zn > Cr > Cu > Pb. The study area was seriously polluted by Cd and As, slightly polluted by Zn, and had relatively little contamination by Cr, Pb, and Cu. In terms of the average Nemerow synthetic pollution index in every sampling site, 97.78% of the samples were seriously polluted and 2.22% of the samples were moderately polluted, which indicated that almost all of the samples in the industrial area were seriously polluted. The results of the biomass, heavy metal concentrations, bioconcentration factors (BCF), and translocation factors (TF) for the native plants showed that Achnatherum splendens for metal Cr presented a phytostabilization potential, Artemisia scoparia and Echinochloa crusgalli for metal Cu and Halogeton arachnoideus for metal Zn presented a phytoextraction potential, and all of the studied plants were limited as phytoremediators for Cd or Pb contaminated soil.
