Abstract To improve our understanding and guide future studies applications, we review the biogeochemistry of rare earth elements (REE). The REEs, which form a chemically uniform group due to their nearly identical physicochemical properties, include lanthanide series plus scandium (Sc) yttrium (Y). These elements, in conjunction with neodymium isotopes, are powerful tools for key oceanic, terrestrial, biological even anthropogenic processes. Furthermore, unique properties render them...
Increased Rare earth elements (REE) usage culminates in discharges into the environment. Mussels have been chosen as models biomonitoring, hence, REE concentrations Mytilus galloprovincialis from six locations on Portuguese coast were accessed to determine natural and possible linkage local ecosystem characteristics temporal variations, by determining them distinct seasons (autumn spring). Samples Porto Brandão (located south bank of Tagus estuary) exhibited highest concentrations, while...
The continuous progress of global manufacturing and anthropogenic activities has resulted in excessive environmental metallic pollution, particularly with rare earth elements (REEs) which have become a prevalent issue concern due to their high toxicity widespread existence. REEs-contaminated soils could ruin agriculture by inducing plant physiology disturbances various crops that are considered the principal link human food chain. main purpose present work is assess phytotoxicity two light...
Rare earth elements (REEs) present a group of nonessential metals for the growth and development plants. At high concentrations, they can induce internal stress disturb physiological biochemical mechanisms in The potential uptake lanthanum (La) cerium (Ce) by horticultural plant Helianthus annuus effect these on its growth, absorption macroelements, contents phenolic compounds flavonoids were assessed. plants exposed to 0, 1, 2.5, 5, 10 µM La Ce 14 days. results showed remarkable...
Soil contamination by toxic trace metal elements, like barium (Ba), may stimulate various undesirable changes in the metabolic activity of plants. The plant responses are fast and with, direct or indirect, generation reactive oxygen species (ROS). To cope with stress imposed ROS production, plants developed a dual cellular system composed enzymatic non-enzymatic players that convert ROS, their by-products, into stable nontoxic molecules. assess Ba response two Brassicaceae (Brassica juncea,...
Humans have exhaustively combusted fossil fuels, and released pollutants into the environment, at continuously faster rates resulting in global average temperature increase seawater pH decrease. Climate change is forecasted to exacerbate effects of such as emergent rare earth elements. Therefore, objective this study was assess combined rising (Δ = + 4 °C) decreasing - 0.4 units) on bioaccumulation elimination gadolinium (Gd) bioindicator bivalve species Spisula solida (Surf clam). We...
Rare earth elements were extensively employed for many years to improve plant growth in farming. However, their effect on plant’s behavior relies concentration and the species. The impact of low doses lanthanum (La; 1–10 µM) growth, mineral uptake, production secondary metabolites was assessed two Brassicaceae species (Cakile maritime Brassica juncea) after 14 days La exposure. accumulation potential also evaluated. Results showed that both able maintain good dry biomass under La. C....
