The escalating environmental impact of rare earth elements (REEs) in freshwater ecosystems, exemplified by Hongze Lake's increasing pollution levels from sediment-bound nutrients and REEs due to human activities, necessitates a comprehensive study. Our objectives are unravel the spatial distribution patterns surface sediments assess their combined toxicity effects on aquatic biota, aiming fill critical gap understanding ecological toxicological risks associated with these contaminants. This study employed diffusive gradients thin films (DGT) technique analyze China's Lake for REEs. Significant fluctuations were observed concentrations phosphate (PO4–P), nitrate (NO3–N), ammonium (NH4–N), some exceeding predicted no effect (PNEC) organisms. Correlation analysis suggested complex interrelationships among elements, indicating potential common sources. Factor condensed 16 variables into 4 factors, unveiling distinct lake. Additionally, probabilistic ecotoxicological risk assessment, integrating DGT-labile data, revealed 1.26% probability inducing toxic biota. These findings provide specific numerical insights sources within ecosystem. results offer valuable information current future lake management conservation efforts.

In‐use dissipation of technology‐critical elements from vehicles and renewable energy technologies in Vienna, Austria: A public health matter?

Abstract The rollout of electric vehicles and photovoltaic panels is essential to mitigate climate change. However, they depend on technology‐critical elements (TCEs), which can be harmful human health whose use rapidly expanding, while recycling lacking. While mining has received substantial attention, in‐use dissipation in urban areas so far not been assessed, for example, corrosion abrasion vehicle components weather‐related effects affecting thin‐film panels. Therefore, the question arises extent TCEs dissipate during potential non‐occupational impacts could occur. We assessed available information concerns conducted exploratory modeling technology stocks, in‐ outflows, neodymium, dysprosium, lanthanum, praseodymium, cerium, gallium, germanium, tellurium contained 21 renewable energy technologies, Vienna, Austria.

Sufficiency‐based measures reduce demand well below levels with continued trends, thus highlighting need combine decarbonization demand‐reducing measures. These results help assess future inform discussions about public hazards associated exposure accumulating environment.
