“…REEs are ingredients of several different minerals and can also be concentrated in phosphorites, being included in quite common minerals such as monazite ((CeLa)PO 4 ), bastnasite ((Ce F )CO 3 ), cheralite ((Ce, La, Y, Th)PO 4 ), and xenotime (YPO 4 ) [ 40 ], or as impurity elements spread in rock-forming minerals and rare metal minerals via isomorphic substitution. Such minerals are often mentioned as REE-containing minerals (e.g., apatite and fluorite) [ 47 ]. Mleczek et al [ 44 ] mentioned that REE concentrations in the following few years may be related to a major new form of environmental pollutants, and this increase may also pose a hazard to both plant and human health.…”

“…Wiche and Heilmeier [ 72 ] found the mean concentrations of La as representative for the REEs ranged from 24 to 146 ng g −1 in grasses ( Hordeum vulgare , Zea mays , Avena sativa , P. miliaceum , and Phalaris arundinacea ) and 20–250 ng g −1 in herbs ( Lupinus albus , Lupinus angustifolius , Fagopyrum esculentum , and Brassica napus ) when grown in soil from a road construction site or mining affected area containing 25–26 µg g −1 total La. With the exception of hyperaccumulating plants, the content of REEs in plants is generally very low [ 47 ]. In general, the concentration of REEs in plants is influenced by several factors, namely soil properties, e.g., pH and total C, cation exchange capacity, redox potential, availability and nature of other elements, e.g., N, P, Ca, Mg, and Al, and plant species, especially in regard to root characteristics [ 47 ].…”

Mining activity has an adverse impact on the surrounding ecosystem, especially via the release of potentially toxic elements (PTEs); therefore, there is an urgent need to develop efficient technologies to remediate these ecosystems, especially soils. Phytoremediation can be potentially used to remediate contaminated areas by potentially toxic elements. However, in soils affected by polymetallic contamination, including metals, metalloids, and rare earth elements (REEs), it is necessary to evaluate the behavior of these toxic elements in the soil-plant system, which will allow the selection of the most appropriate native plants with phytoremediation potential to be used in phytoremediation programs. This study was conducted to evaluate the level of contamination of 29 metal(loid)s and REEs in two natural soils and four native plant species (Salsola oppositifolia, Stipa tenacissima, Piptatherum miliaceum, and Artemisia herba-alba) growing in the vicinity of a Pb-(Ag)-Zn mine and asses their phytoextraction and phytostabilization potential. The results indicated that very high soil contamination was found for Zn, Fe, Al, Pb, Cd, As, Se, and Th, considerable to moderate contamination for Cu, Sb, Cs, Ge Ni, Cr, and Co, and low contamination for Rb, V, Sr, Zr, Sn, Y, Bi and U in the study area, dependent of sampling place. Available fraction of PTEs and REEs in comparison to total concentration showed a wide range from 0% for Sn to more than 10% for Pb, Cd, and Mn. Soil properties such as pH, electrical conductivity, and clay content affect the total, available, and water-soluble concentrations of different PTEs and REEs. The results obtained from plant analysis showed that the concentration of PTEs in shoots could be at a toxicity level (Zn, Pb, and Cr), lower than toxic but more than sufficient or natural concentration accepted in plants (Cd, Ni, and Cu) or at an acceptable level (e.g., V, As, Co, and Mn). Accumulation of PTEs and REEs in plants and the translocation from root to shoot varied between plant species and sampling soils. A. herba-alba is the least efficient plant in the phytoremediation process; P. miliaceum was a good candidate for phytostabilization of Pb, Cd, Cu, V, and As, and S. oppositifolia for phytoextraction of Zn, Cd, Mn, and Mo. All plant species except A. herba-alba could be potential candidates for phytostabilization of REEs, while none of the plant species has the potential to be used in the phytoextraction of REEs.

“…Tao et al reviewed the distribution of REE and their roles in plant growth and found that the contents of REE in plants are generally very low. Besides, coastal vegetated ecosystems (i.e., seagrass, salt marshes, mangroves), in general, show low translocation factors from roots to aboveground tissues. ,,− Nonetheless, species-specific variability in bioaccumulation and translocation factors is high .…”

We sampled abiotic and food web components in an impacted estuarine system to assess the transfer and fate of rare earth elements (REE). REE (based on dry weight) were measured in sediments, suspended particulate matter (SPM), and organisms from different trophic levels. The highest ∑REE concentrations were measured in sediments (180 ± 4.24 mg kg −1 ) and SPM (163 ± 12.6 mg kg −1 ). Phytoplankton (45.7 ± 5.31 mg kg −1 ), periphyton (51.6 ± 1.81 mg kg −1 ), and zooplankton (68.5 ± 1.27 mg kg −1 ) are the major sources of exposure and transfer of REE to the food web. REE concentrations were several orders of magnitude lower in bivalves, crustaceans, and fish (6.01 ± 0.11, 1.22 ± 0.18, and 0.059 ± 0.003 mg kg −1 , respectively) than in plankton. The ∑REE declined as a function of the trophic position, as determined by functional feeding groups and δ 15 N, indicating that REE were subject to trophic dilution. Our study suggests that the consumption of seafood is unlikely to be an important source of REE for humans. However, given the numerous sources of dietary introduction of REE, they should be monitored for a possible harmful cumulative effect. This study provides new key information on REE's baseline concentrations and trophic transfers and patterns.

“…REEs have been widely used in agriculture, technological devices, medicine, and superconductors (Tao et al, 2022). Though REEs are not essential elements for plant growth, REEs enriched fertilizers have been widely applied in agriculture in China (Hu et al, 2004; Liu, Wang, & Chen, 2012).…”

In the current study, the effect of trivalent cerium (Ce 3+ ) on the production of reactive oxygen species (ROS) was investigated in the root of Arabidopsis thaliana by an in vitro study. The roots of A. thaliana were exposed with 0, 1, and 5 μmol/L Ce 3+ for 12 h in vitro. It was found that the level of H 2 O 2 , O 2 .À , and ÁOH was enhanced by 5 μmol/L Ce 3+ , but reduced by 1 μmol/L Ce 3+ . The activities of peroxidase (POD), catalase (CAT), and superoxidase dismutase (SOD) were enhanced by 1 μmol/L Ce 3+ , but reduced by 5 μmol/L Ce 3+ . Moreover, we used a laser-scanning confocal microscopy to detect the changes of ROS in the root cells of A. thaliana by using a fluorochrome 2 0 ,7 0dichlorofluorescein diacetate (H 2 DCF-DA). It showed that the level of ROS was declined in the root cells treated by 1 μmol/L Ce 3+ , but the oscillation of ROS was found in the root cells treated with 5 μmol/L Ce 3+ . In addition, REEs affect the uptake of mineral elements, which may be related to the oxidative stress in the cells of roots. In all, the data of our study indicated that the appropriate concentration of Ce 3+ exhibited an antioxidation property and improved the defense system in the root cells of A. thaliana.
