“…In addition, these results are in agreement with a study done by Wu et al ( 2021) [17] on the accumulation of metals in native plants of a pyrite mine in China. Similar to the results of the present study, they found high total Cu concentrations in tailings and far exceeded the Class-II standard for China's soil and environmental quality.…”

“…Similar to the results of the present study, they found the Festuca ovina species to be suitable for phytostabilization of phosphates. Moreover, this study agrees with that of Wu et al (2021) [17] on the phytoremediation of a pyrite mine in China. Like the results of the present study, they found also Asteraceae suitable for the phytostabilization of the mine tailings (Chrysanthemum indicum, Conyza canadensis, Senecio scandens).…”

“…The solution is to select dominant plants that grow spontaneously in the region with a capacity for phytoremediation. The selection of plant species from contaminated areas is an important condition for a future systemic phytoremediation because it allows one to target plants capable of tolerating a high concentration of metals [10][11][12][13][14][15][16][17].…”

The abandoned Kettara pyrrhotite mine (Marrakech region, Morocco) is a real source of acid mine drainage (AMD) and heavy metal pollution from previous mining operations—which has spread, particularly because of wind erosion. A store-and-release cover system made of phosphate wastes was built on the site for preventing AMD. To ensure the integrity of this cover and its durability, it is desirable to revegetate it (phytostabilization) with plants adapted to the edaphoclimatic conditions of the region. In this paper, a study was carried out on the spontaneous vegetation around the phosphate cover in order to consider the selection of plants to promote the stabilization of the Kettara mine tailings pond. Nine species of native plants with their rhizospheric soils growing in agricultural soils and tailings from the Kettara mine were collected, and metals (As, Cd, Co, Cu, Pb, Zn, Ni, Cr) were analyzed. The soil analysis showed that the tailings contained high concentrations of Cu (177.64 mg/kg) and Pb (116.80 mg/kg) and that the agricultural soil contained high concentrations of As (25.07 mg/kg) and Cu (251.96 mg/kg) exceeding the toxicity level (Cu > 100 mg/kg, Pb > 100 mg/kg, As > 20 mg/kg). The plant analysis showed low trace metal accumulation in Scolymus hispanicus, Festuca ovina, Cleome brachycarpa, Carlina involucrata and Peganum harmala. These species had a bioconcentration factor (BCF) greater than 1 and a translocation factor (TF) less than 1, demonstrating a high tolerance to trace metals. Therefore, they are good candidates for use in the phytoremediation of the Kettara mine tailings. These species could also potentially be used for the phytostabilization of the phosphate waste cover of the Kettara mine, thus completing the rehabilitation process of this area.

“…One major point of concern for environmental and public health is contamination by mining activities [ 1 ], where the negative effects of heavy metal contamination have been observed in the surrounding water, soil, and air environments of the mine sites [ 4 , 5 , 6 ]. In the case of abandoned mine tailing impoundments, negative environmental impacts have been identified, including an increase in the concentration of metals in agricultural soils, sediments, animals, human beings, and plants [ 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ]. Among the various heavy metals, chromium (Cr) is widely present in soils, with an average concentration of 60 mg kg −1 [ 16 ].…”

In Chile, there are several abandoned mine tailing impoundments near population centers that need to be remediated. In this study, the ability of Oxalis gigantea, Cistanthe grandiflora, and Puya berteroniana to remove Zn, Ni, and Cr from mine tailings was evaluated. The plants’ removal efficiency, bioconcentration, and translocation factors regarding these metals were determined to assess the ability of certain endemic species from Northern and Central Chile to extract or stabilize metals. After a period of seven months, the chemical analysis of plants and tailings, together with the statistical treatment of data, indicated the inability of all the species to translocate Ni, Cr, or Zn with a translocation factor lower than one. The results showed the stabilizing character of Oxalis gigantea, Puya berteroniana, and Cistanthe grandiflora for Zn, with a bioconcentration factor close to 1.2 in all cases, and the same ability of the latter two species for Cr, with a bioconcentration factor of 1.5 in the case of Cistanthe grandiflora and 1.7 for Puya berteroniana. Finally, a removal efficiency of 9.3% was obtained with Cistanthe grandiflora for Cr and 15% for Ni; values lower than 6.4% were obtained for Zn in all cases. Improvements in the process should be sought to enhance the performance of these species for the accumulation of the target metals.

“…In many cases, they have used alien plant species that can become invasive and deteriorate the native flora, representing a threat to ecosystems [ 1 , 37 ]. Different studies propose the use of native plants growing in areas to be remediated and/or restored for the environmental benefits and reduction of treatment costs [ 35 , 38 , 39 ]. It is important to highlight that plants growing in contaminated areas have higher resistance through more efficient exclusion or higher accumulation and tolerance to potentially harmful concentrations of contaminants than those plants growing in uncontaminated soils [ 37 , 40 ].…”

Soils contaminated by potentially toxic elements (PTEs) as a result of anthropogenic activities such as mining are a problem due to the adverse effects on human and environmental health, making it necessary to seek sustainable strategies to remediate contaminated areas. The objective of this study was to evaluate the species Clidemia sericea D. Don for the phytoremediation of soils contaminated with PTEs (Hg, Pb, and Cd) from gold mining activities. The study was conducted for three months, with soils from a gold mining area in northern Colombia, and seeds of C. sericea, under a completely randomized experimental design with one factor (concentration of PTEs in soil) and four levels (control (T0), low (T1), medium (T2), and high (T3)), each treatment in triplicate, for a total of twelve experimental units. Phytotoxic effects on plants, bioconcentration (BCF), and translocation (TF) factors were determined. The results obtained for the tissues differed in order of metal accumulation, with the root showing the highest concentration of metals. The highest values of bioconcentration (BCF > 1) were presented for Hg at T3 and Cd in the four treatments; and of translocation (TF > 1) for Hg and Pb at T0 and T1; however, for Pb, the TF indicates that it is transferable, but it is not considered for phytoextraction. Thus, C. sericea demonstrated its potential as a phytostabilizer of Hg and Cd in mining soils, strengthening as a wild species with results of resistance to the stress of the PTEs evaluated, presenting similar behavior and little phytotoxic affectation on the growth and development of each of the plants in the different treatments.
