The current socio-economic, environmental and public health challenges that countries are facing clearly need common-defined strategies to inform support our transition a sustainable economy. Here, the technology-critical elements (which includes Ga, Ge, In, Te, Nb, Ta, Tl, Platinum Group Elements most of rare-earth elements) great relevance in development emerging key technologies-including renewable energy, energy efficiency, electronics or aerospace industry. In this context, increasing...
Rare earth elements (REEs) or lanthanides are often found together in nature, and they used multiple anthropogenic activities from green energy medical technologies to telecommunications defense systems. However, the current understanding on concentration behavior of REEs oceans marine organisms is limited, no regulatory information limits have been settled. Here, we present a review concentrations waters biota. reach aquatic ecosystems mainly by continental contributions, maximum reported...
The determination of trace elements using stripping voltammetry may be seriously affected by the presence intensive matrix background or interfering peaks, leading to poorer detection limits and/or inaccurate quantitative results. In this work, we have tested use signal transformation (e.g., second derivative) in analysis platinum seawater and sediment digests means catalytic adsorptive voltammetry. natural waters, limit Pt is a broad wave due formazone complex used sample for its...
The uptake of platinum group elements (PGE) by different preparations estuarine sediment suspended in filtered river water has been examined. For a given PGE, adsorption time courses to untreated and whose hydrous metal oxides or organic matter had removed appropriate chemical treatments were similar. Adsorption Rh(III) Pt(IV) proceeded via first-order reversible reaction. Rh, forward rate constants 1 order magnitude greater than reverse constants, but for Pt, comparable. Respective system...
The development in recent years of new technological and energy-related applications has increased the use demand a specific group trace elements (Technology-Critical Elements, TCEs). Among TCEs, there are number (Nb, Ta, Ga, In, Ge, Te) for which their biogeochemical cycles ecotoxicology uptake by biota been scarcely studied; they known as Less-Studied TCEs (LSTCEs). Here we present review on concentrations LSTCEs marine waters biota. We show that whereas oceanic profiles have reported all...
There is a current interest in the study of geochemical behavior rare earth elements (REE) aquatic systems since their identification as potential microcontaminants natural waters. In this context, here we report concentrations and patterns dissolved REE (dREE) waters Gulf Cádiz (GoC) its major estuaries (Guadiana, Tinto-Odiel Guadalquivir). Contamination area by metals has been extensively reported, linked to acid-mine inputs resulting from mineralization Iberian Pyrite Belt, discharged...
This study delves into the intricate interplay between ocean acidification (OA), metal bioaccumulation, and cellular responses using mussels (Mytilus galloprovincialis) as bioindicators. For this purpose, environmentally realistic concentrations of isotopically labelled metals (Cd, Cu, Ag, Ce) were added to investigate whether OA increase would modify bioaccumulation induce adverse effects at level. The reveals that while certain elements like Cd Ag might remain unaffected by OA,...
