This study investigated the multi-level adverse effects of gadolinium (Gd³⁺), a representative REE contaminant, on Euglena gracilis by integrating physiological, ultrastructural, and non-targeted metabolomic approaches. While background environmental concentrations of Gd are low, levels in anthropogenically impacted systems can exceed ∼60 mmol/L, providing the context for this toxicological investigation. Gd³⁺ exhibited potent, dose-dependent toxicity, causing a 35.77 % inhibition of growth at 80 μmol/L, with a calculated EC₅₀ for growth inhibition of 110.5 μmol/L (95 % CI: 95.8-127.5 μmol/L), alongside detrimental morphological shifts and severe chloroplast damage. While total photosynthetic pigments and paramylon decreased in the culture, their per-cell levels paradoxically increased, signifying a severe cellular stress response. Non-targeted metabolomics revealed extensive metabolic reprogramming, with lipid metabolism identified as the primary target of Gd³⁺-induced cellular damage, accounting for 65.8 % of the differential metabolites. This disruption included the significant upregulation of lysophospholipids, a nearly 400-fold increase in the signaling molecule 12-HETE, and the perturbation of key bioenergetic pathways like oxidative phosphorylation. In conclusion, Gd³⁺ exerts multi-target toxicity in E. gracilis through direct chloroplast damage, drastic reprogramming of lipid metabolism leading to membrane disruption and altered signaling, and consequent disorders in energy metabolism. These findings advance REE ecotoxicology and highlight that the disruption of lipid metabolism is a key toxic mechanism and a potential sensitive biomarker for REE-induced hazardous effects, providing crucial evidence to inform environmental risk assessments and establish water quality benchmarks for these materials.</p>","PeriodicalId":312,"journal":{"name":"Environmental Research","volume":" ","pages":"122993"},"PeriodicalIF":7.7,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145211267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

American alligators (Alligator mississippiensis) are top predators in the coastal aquatic ecosystems of the Gulf of Mexico and are a sentinel species for ecosystem health due to their longevity and high trophic position. However, knowledge on the extent of ECs exposures and likely health impacts on alligators is scarce. This study measured select ECs and blood biochemistry parameters in alligator plasma opportunistically sampled at the Rockefeller Wildlife Refuge in southwest Louisiana. The analysis showed the prominent occurrence of 6 ECs in the plasma: amphetamine (AMP), atenolol (ATN), ketoprofen (KTP), naproxen (NPR), nicotine (NCT), and perfluorooctane sulfonate (PFOS). AMP and PFOS were most prevalently detected in the plasma samples (95% and 100% detection frequency, respectively), and exhibited the highest concentrations (mean ± SEM; AMP: 7.05 ± 3.02 ng/mL, PFOS: 5.95 ± 0.57 ng/mL). The detection of the other ECs ranged from 46 - 69% and with mean concentrations approximately an order of magnitude lower than that of PFOS or AMP. While the biochemistry parameters were all within physiologically acceptable ranges, partial redundancy and correlation analyses suggested positive correlations between the total number of detected pharmaceuticals, ATN, and PFOS, with biochemical parameters associated with liver, kidney, and muscle injury; and endocrine disruption.

In practical application, the batch-to-continuous operational strategy is advantageous to maximize volatile fatty acids (VFAs) production. However, it remains unclear how this strategy impacts microbial metabolic activity and succession process. In this study, a WAS fermentation system was constructed under batch mode for 12 days, followed by long-term semi-continuous operation with a short sludge retention time (SRT) of 4 days. Results showed that after the mode changed to semi-continuous, the reactor gradually gained good VFAs-producing performances, stabilized at an acidification ratio of 70 %. The ecological network structure of semi-continuous stage became more stable, characterized by higher modularity and lower betweenness centralization. Although the batch stage provided sufficient substrates, the metabolic activity of fermentative microbes was initially inhibited by the shift in fermentation mode and restored via adaptive mechanisms (two-component system and quorum sensing). The null model analysis revealed that deterministic selection, governed by the short SRT, dominated microbial community assembly. This process enriched hydrolytic and acidogenic bacteria while excluding VFAs consumers, with diffusion limitation further enhancing community stability. Overall, for batch-to-continuous anaerobic fermentation, the batch stage laid a foundation for an efficient metabolism throughout later periods, while in the semi-continuous stage, the short SRT served as an environmental filter, promoting the succession of hydrolytic and acidogenic bacteria, meanwhile excluding VFAs consumers. These findings provide a comprehensive insight into the mechanisms of community assembly in sludge fermentation, offering a theoretical support for potential community design and reactor regulation.</div></div>","PeriodicalId":312,"journal":{"name":"Environmental Research","volume":"286 ","pages":"Article 122980"},"PeriodicalIF":7.7,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145211183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
