The temperatures used had an impact on the extrapolated y₀, but the consequences should be limited due to low values. Upon lifting the materials in the cell, the steady state gas phase concentration was close to y₀. This configuration can be used for quick y₀ estimation. The benefit of this method is the ability to estimate y₀ at any temperature which is useful to estimate exposure under different scenarios.</div></div>","PeriodicalId":276,"journal":{"name":"Chemosphere","volume":"385 ","pages":"Article 144564"},"PeriodicalIF":8.1,"publicationDate":"2025-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144653174","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}

Antibiotic contamination is of particular concern due to their high persistence and ability to promote the development of resistance genes. However, limited information is available regarding the behavior of antibiotic metabolites. In this study, seventeen antibiotics and metabolites of five therapeutic groups of critically and highly important antibiotics were monitored in wastewater and sludges from fifteen wastewater treatment plants (WWTPs) with five different sludge stabilization treatments: anaerobic digestion, aerobic digestion, dehydration, composting, and lagooning. Results demonstrated that the distribution ratio of metabolites and parent compounds in influent wastewater was correlated with their excretion rates, reflecting pharmaceutical consumption as their primary source to WWTPs. Fluoroquinolone and sulfonamide antibiotics were predominant in influent wastewater, while macrolide antibiotics were more prevalent in primary sludge, likely due to their higher hydrophobicity, which results in greater retention in sludge. Parent compounds dominated over metabolites in sewage sludge, with composting plants showing the highest removal efficiency and highest metabolization among all sludge stabilization technologies studied. Tetracyclines were not detected in any of the sludge samples analyzed and macrolides resulted in the most persistent antibiotics in treated sludges.

Traditional recycling methods often rely on toxic organic solvents, highlighting the urgent need for safer, more sustainable alternatives. In this study, a novel task-specific deep eutectic solvent (DES) composed of dibenzoylmethane (DBM) and trioctylphosphine oxide (TOPO) in a 1:1 molar ratio was developed for selective lithium extraction. Unlike conventional DESs, the DBM/TOPO-DES is hydrophobic, enabling efficient liquid–liquid extraction by minimizing miscibility with aqueous solutions. Under optimized conditions—pH 12, 30 s of vortexing, room temperature, and a 2:1 aqueous-to-DES phase ratio—the system achieved over 99% lithium extraction efficiency. It also exhibited high extraction efficiency with EDTA as a masking agent for lithium in the presence of commonly co-existing ions such as Co(II), Cu(II), and Ni(II), typically present in LIB cathode materials. Lithium was efficiently back-extracted using 0.7 M HCl, and the DES maintained excellent performance across five extraction cycles, demonstrating its reusability. Compared to other DES-based approaches, this system combines rapid kinetics, high extraction efficiency, and a greener profile without compromising performance. Thermal analysis, phase behavior, and spectroscopic characterization confirmed the stability and formation of the DES. Overall, the DBM/TOPO-DES offers a sustainable and effective alternative to traditional solvent systems, advancing green chemistry principles and contributing to the efficient recovery of critical lithium resources from spent batteries.</div></div>","PeriodicalId":276,"journal":{"name":"Chemosphere","volume":"385 ","pages":"Article 144556"},"PeriodicalIF":8.1,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144595873","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}

This review explores the impact of environmental contamination on the hypothalamic–pituitary–adrenal (HPA) axis, a key endocrine system involved in stress responses, whose chronic dysregulation may lead to adverse health outcomes. Existing evidence suggests that environmental pollutants can interfere with the production and regulation of steroid hormones, such as glucocorticoids, aldosterone, and dehydroepiandrosterone sulfate, potentially triggering HPA axis dysfunction and prolonged stress responses. However, substantial knowledge gaps remain, particularly concerning free-ranging cetaceans, highlighting the need for integrated assessments that combine hormonal and contaminant analyses.
