“…A similar behaviour has been observed for plants growing in soils of high natural REE concentrations (Miekeley et al, 1994). However, the preferential uptake of light REE observed in culture experiments with radish plants is also reported in a recent study (Tagami and Uchida, 2006).…”

“…3). It was shown in laboratory experiments that transfer of REEs from nutrient solutions via root uptake to plants (including E. crassipes) increases linearly with the concentration of these elements in the solution phase (Chua, 1998;Tagami and Uchida, 2006). As regard to the high REE concentrations observed in all species here studied, this finding may be related to the physicochemical similarities between REEs and Ca, the latter an essential element to plants and present in high concentrations (Table 5).…”

Aquatic macrophytes are well known accumulators for heavy metals, the reason why they are used as bioindicators for water quality and in phytoremediaton strategies. This study reports on the elemental concentrations in four free-floating aquatic macrophytes (S. auriculata; P. stratiotes; E. crassipes and E. azurea) growing in two water reservoirs (Santana e Vigário, Rio de Janeiro State, Brazil) of an electric power plant that receive input from the polluted Paraíba do Sul River. Filtered water samples and water suspended solids from these environments were also analysed. Inductively coupled plasma mass spectrometry was used as the principal method, allowing the determination of up to 41 elements, including the rare-earth elements (REEs) and other trace metals not assayed before in these macrophytes. The results show that all elements studied are accumulated by the macrophytes R. S. Valitutto · S. M. Sella ( ) · E. V. Silva-Filho (PUC-Rio), 22451-900, Rio de Janeiro, Rua Marquês de São Vicente, 225 with concentration ratios (CR = [plant]: [water]) varying from about 1,000 to 200,000, based on the dry weight of the plant species. With a few exceptions, highest accumulations were observed in E. crassipes in which CRs increase in the sequence: Cu < Mo < Cr < Pb < Tl < Fe < La < Zn < Ce< Mn. Surprisingly high CRs (e.g. Ce: 74,000) and corresponding mass concentrations were observed for the rare-earth elements (e.g. REE: 112 mg kg −1 ), also measured in the water suspended particle fraction. The results show that this fraction acts as an effective sink for trace metals in the aquatic system studied and seems to play also an important role in the transfer of metals from water to the plant species.

“…These authors highlighted that La was extremely mobile in this environment since La contamination was present more than 400 km after the source of the contamination. Tagami and Uchida (2006) provided evidence that REE are able to accumulate in soils and waters and to bioaccumulate in the food chain. Sonich-Mullin (2013) compiled the studies concerned with the specific human health effects of elevated REE concentrations.…”

Biogeochemical Factors Affecting Rare Earth Element Distribution in Shallow Wetland Groundwater

et al. 2014

Wetlands are specific areas able to regulate metals mobility in the environment. Among metals, rare earth elements (REE) appear to be particularly interesting because of the information that could be provided by the REE patterns. Moreover, as REE are becoming a matter of great economic interest, their significant release into the environment may be expected over the next few decades. Wetlands would then play a key role in the regulation of their concentration in the environment. This review demonstrated that REE are released in wetland bound to colloidal organic matter. During the flood season, the released REE concentrations are largely higher than those released during the wet period. This solubilization is related to the organic matter desorption caused by the pH rise imposed by the reducing reactions. The resulting REE patterns depend on the heterogeneity of the humic acid (HA) binding sites and the presence of potential competitive cations, such as Fe(III) and Al(III). At high REE loading, REE are bound to HA carboxylic groups and the pattern exhibit a MREE downward concavity. At low loading, REE are bound to phenolic and chelate groups and the pattern exhibits a lanthanide contraction. At low loading, REE seem to act as cationic bridges between two organic molecules, whereas at high loading they seem to be engaged in strong multidentate bonding. Moreover, the REE patterns can be modified with the competitive cations amount and speciation. The prime factor governing all these processes is pH, which drives the organic colloid production, REE loading and solubility of competitive cations.

“…-Early in the 1940s, it was found that rare earth elements (REEs) can be used to facilitate plant growth, especially in enhancement of plant root and germination, increment of chlorophyll content, and reinforcement of photosynthesis and nutrients absorption [1]. Since the 1970s, an increasing number of REEs have been added to fertilizers used in crop production [2] [3]. Many studies showed that, because of their similarity to Ca II regarding ionic radii, coordination chemistry, and preference for O-donor groups, the REEs exerted similar biological and physiological effects on organisms; in particular, enhancement of plant growth [4] [5].…”

Rare earth elements (REEs) have beneficial influence on plant growth and are widely used in agriculture practice, but little is known about the behavior of the REEs in mitochondria of plant cell. Thermogenic metabolic curves were determined by the ampoule method at 303 K using a TAM air isothermal microcalorimeter in mitochondria isolated from hybrid rice Liangyoupeijiu (Oryza sativa L.), and the effect of La(III) on its mitochondrial metabolism was investigated. From the obtained heat flux curves, the crucial parameters including as activity recovery rate constant (k) and maximum heat power (P(max)) were determined. Application of La(3+) in concentrations ranging from 0 to 120 microg/ml significantly increased k and P(max) values with the high point reaching 346 and 222% of the control, respectively. Concentrations from 140-150 microg/ml had the opposite effect. These results were consistent with previous reports on the effects of REEs on plant growth. It was concluded that the La-induced change of mitochondrial metabolic activity is a possible mechanism by which La(III) ions influences hybrid rice growth.
