“…Because of their unique physicochemical properties (e.g., naturally coherent behaviour, high lustre and electrical conductivity; Topp, 1965), REEs are widely and intensively applied in numerous high-tech, medical and agricultural products and processes (US. EPA, 2012), being potentially released into the aquatic environments worldwide (Khan et al, 2017). Bau and Dulski (1996) studies were among the first ones that related rising levels of REEs in aquatic environments with anthropogenic activities, revealing a positive correlation between REE Gadolinium (Gd) concentration and riverine inputs from densely industrialized areas.…”

Ecotoxicological effects of lanthanum in Mytilus galloprovincialis: Biochemical and histopathological impacts

Highlights  Mytilus galloprovincialis bioaccumulated lanthanum  Mussels exposed to Lanthanum decreased their metabolic capacity  Contaminated mussels activated their antioxidant and biotransformation defences  Contaminated mussels showed increased lipid peroxidation and lower GSH/GSSG ratio  Neurotoxicity was induced in contaminated mussels  Histopathological alterations were induced by lanthanum Summary Inappropriate processing and disposal of electronic waste contributes to the contamination of aquatic systems by various types of pollutants such as the rare-earth elements (REE) in which lanthanum (La) is included. Knowledge on the toxicity of these elements in marine organisms is still scarce when compared to other metals such as mercury (Hg) and arsenic (As).

“…Distribution, pollution, and ecological risks of rare earth elements in soil of the northeastern Qinghai-Tibet Plateau Introduction Rare earth elements (REEs) are generally defined as a homogenous group of 17 elements with identical physic-chemical properties including scandium (Sc), yttrium (Y), and 15 lanthanides with atomic numbers from 57 to 71 (Hu et al 2006;Khan et al 2017), exhibiting similar environmental behaviors. REEs comprise light rare earth elements (LREEs) and heavy ones (HREEs).…”

Information on rare earth elements (REEs) in soils of the Qinghai-Tibet Plateau is very limited. Therefore, this study performed field sampling to explore the concentrations, contamination degree, and potential ecological risks of REEs in soil of the northeastern Qinghai-Tibet Plateau. Concentrations of total REEs (TREEs) ranged from 95.82 to 544.01 mg/kg with average value of 241.81 mg/kg. Light REEs accounted for 72.3%-84.2% of TREEs, whereas Ce was the dominant element. Four methods were employed to evaluate the pollution of soil REEs. About 45.7% of sampling sites exhibited uncontaminated to moderately contaminated levels based on geoaccumulation index values of TREEs. Over 95.7% of sampling sites exhibited deficiency to minimal enrichment based on enrichment factor values of TREEs. The pollution load index evaluation results illustrated that about 85.7% of sampling sites possessed moderate levels of pollution, more serious than those evaluated by modified degree of contamination method. The potential ecological risk indexes of soil REEs in study area ranged from 11.02 to 40.55, showing low risk levels. This study provided important information on REEs in soils of the northeastern Qinghai-Tibet Plateau for soil pollution prevention and control at the highelevation areas.

“…The wide use of REEs in numerous industrial fields enhances the risk for these elements to potentially reach the freshwater and marine environments (Khan et al, 2017), thus increasing the possible threats to these systems and, in particular, to inhabiting wildlife. The increased REEs levels observed in aquatic environments was revealed for the first time, among others, by Bau and Dulski (1996), who described a positive correlation between gadolinium (Gd) concentrations and freshwater inputs from areas with higher occurrence of industrial plants.…”

More research on gadolinium (Gd) occurrence in freshwater than marine environments • Few publications on the accumulation and effects of Gd in aquatic invertebrates • Higher diversity of freshwater species than marine species in Gd impacts studies. • Aquatic invertebrates differently bioaccumulate Gd according to its speciation. • Gd causes alterations at different biological levels in aquatic invertebrates.
