Due to a growing concern about some of these compounds, industries have introduced new PFAS varieties with supposedly less harmful properties. In this study, different fabric samples from carpets, curtains and sofas (n = 30) were analyzed after a solvent extraction and an Envi-Carb clean-up for 81 PFAS, including legacy PFAS and 43 newly synthesized precursors, mainly perfluoroalkane sulfonamide derivatives by liquid and gas chromatography – mass spectrometry. In total, 28 PFAS were detected in the fabric samples. Fluorotelomer alcohols showed the highest concentrations in the fabrics (1–2329 μg/m²). Perfluoroalkyl sulfonic acids (PFSAs) and perfluoroalkyl acids (PFAAs) were also detected but at lower concentrations (e.g., 0.02–1.71 μg/m² for PFHxA, 0.01–1.97 μg/m² for PFBS). Perfluoroalkane sulfonamide precursors such as MeFBSAA, FBSE, MeFBSE, FBSA, and MeFBSEA were primarily found in carpet and curtain samples, accounting for approximately 10 % and 24 % of the total PFAS concentration in these matrices, respectively. These precursors were predominantly fully fluorinated compounds with 4-carbon chains. These precursors mostly correspond to fully fluorinated 4-carbon chain-PFAS and may be in accordance with the higher use of shorter PFAS compounds observed in recent years but more samples should be tested to confirm this assumption.</div></div>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"993 ","pages":"Article 180006"},"PeriodicalIF":8.2,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144536140","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Currently, geological disposal has been widely regarded as the most effective method for long-term waste management.

The process can be enhanced by preferential flow paths, particularly in the presence of colloids. Therefore, a comprehensive understanding of the collaborating effects of preferential flow and colloids is critical for ensuring reliable repository assessments. In this paper, the interactions mechanisms between radionuclides and colloids that delaying the transport of radionuclides are first summarized with corresponding mathematical descriptions. The advanced modeling techniques are then assessed by describing colloid-facilitated radionuclide transport with different conceptual framework under the effect of preferential flow.

Prediction of species' aggregation dynamics remains a challenge in studies of their distribution patterns. Species distribution models (SDMs) are statistical tools for understanding spatial patterns of marine biodiversity, ranging from essential species habitat, assessing fisheries bycatch, and projecting future distribution changes. SDMs involving pelagic species abundance generally do not typically resolve aggregation patterns. We use a 20-year observation record of seabird species aggregations, with seabirds being the most easily quantified “pelagic” species, to develop SDMs and a regional ocean modeling system to identify physical drivers and changes in aggregation location and intensity over time. We apply a conceptual ecosystem model to organize environmental covariates according to habitat production within coastal upwelling systems. The SDM used a 2-step modeling approach: a presence/absence model and a binary aggregation model. Thus, we aim to predict factors that characterize baseline ocean habitat for a species (presence/absence) and that aggregate large numbers of the species. Prediction of seabird aggregation results in realistic spatial distribution patterns that reflect known species habitat associations. Temporally, aggregation indices indicate mixed responses both within and between resident and migrant species, reflecting interannual effects of warm/cool ocean years and mesoscale structure supporting enhanced or decreased productive foraging habitat. The most abundant species were more likely to form aggregations during warmer years, indicating a response to a decrease in productive foraging habitat. The occurrence of species aggregations in spring is predictable by examining ocean-climate conditions in the preceding winter, thus providing a potential early warning system of anticipated ecosystem shifts. We contend that the aggregation occurrence model may improve the realism of pelagic SDMs and their utility for assessing spatial and temporal variability of trophic interactions. We discuss the utility of species aggregation models for quantifying the variability in critical pelagic habitats, the ecology and response of seabird species as indicators, advancement of ecosystem modeling and monitoring, and conservation applications (e.g., bycatch, wind energy, and oil spills).</p>","PeriodicalId":55168,"journal":{"name":"Ecological Applications","volume":"35 5","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eap.70068","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144537194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two network configurations (i.e., with and without elevated water storage tanks) and three electricity tariff structures (i.e., zero, fixed and dynamic purchase or grid feed-in tariffs) have been investigated using two case study systems. It has been found that WDS configurations with elevated tanks typically require larger BTM solar systems, offering greater flexibility in aligning pump operations with solar energy generation. This in turn leads to higher solar energy utilisation and lower total life cycle costs (TLCC) compared to systems without tanks. In contrast, WDSs without elevated tanks tend to have smaller solar PV systems and may have low efficiency in solar energy utilisation. In addition, it has been found that although a fixed grid feed-in electricity tariff offers additional revenue through selling excess solar energy back to the grid, it has minimal impact on solar PV sizes. In contrast, a dynamic electricity tariff structure leads to smaller BTM solar systems but higher TLCC due to the impact of possible negative electricity prices. Overall, this research offers valuable insights into the design and operation of WDSs integrating BTM solar, providing guidance on determining optimal solar PV sizes based on WDS configurations and different electricity tariff structures to maximise economic and energy benefits in these integrated systems.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"520 ","pages":"Article 146069"},"PeriodicalIF":9.7,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144535905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Using high-performance liquid chromatography (HPLC) pigment data from 690 stations collected over 12 bio-optical campaigns (2006–2019), we applied hierarchical clustering, principal component analysis, and network-based community detection to identify dominant phytoplankton groups and characterize their spatial and temporal variability.
