On average, 29 % and 12 % of the carbon fixed by <em>S. latissima</em> was released as DOC from Autumn and Winter deployments, respectively, before the progression of bryozoan biofouling.

This study quantified the water environmental capacity (WEC) of estuarine MPs using species health-based microplastic concentration (MPC) thresholds. Classified MPs simulation employed probability density functions and shape factors to convert mass concentrations into particle counts during the flood season in the Yangtze River estuary. The 5% species hazard concentration (HC₅) with two ecologically relevant metrics was selected as the MPC threshold by correcting the species sensitivity distribution (SSD) curves for polydispersity and biological accessibility of environmental MPs. Lastly, the dynamic WEC framework was established by linking MP simulations to MPC thresholds.

However, nitrogen inevitably accumulates in the form of ammonia during the process, undermining the goal of adding a carbon source to aid bioreactors in nitrogen removal. To address this issue, different N/M_xO_y catalysts were synthesized with noble metal (N=Ru, Pt, Pd) and metal oxide supports (M_xO_y=Al₂O₃, TiO₂, CeO₂, ZrO₂). The entire process comprised the liquefaction of sludge and the subsequent refining of oxidation liquid. The performance of these catalysts was compared using various parameters, including total nitrogen (TN) removal, practical carbon source (PCS) production, and volatile fatty acids (VFAs) production, to ensure both the quantity and quality of the carbon source. Ru/TiO₂ was found to be the best catalyst, achieving a TN removal rate of 94.6% and a PCS concentration of 2760 mg/L under optimized reaction conditions of 260°C, 1.5 MPa O₂, 4.0 h, an initial pH of 7.1, and the addition of 3.0 g/L vacuum-dried catalyst. In general, 110.1 g COD carbon source could be produced per kg dry sludge. The reusability of the catalyst was examined, and PCS only decreased 4.7% after four cycles of usage. The change in other dissolved organic matter was also investigated, with CHON and CHO molecules, as well as lignins and condensed hydrocarbons, being considered the dominant components. This study offers a viable approach for the resource utilization of municipal sludge.","PeriodicalId":443,"journal":{"name":"Water Research","volume":"10 1","pages":"123859"},"PeriodicalIF":12.8,"publicationDate":"2025-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144083260","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}

This study used outdoor ozone concentrations from 47 monitoring stations and a Monte-Carlo approach based on mass balance model to assess exposures to ozone and 23 of its volatile oxidation products across 25 cities in 19 European countries (2015–2019), focusing on four age groups (15+ years). Average indoor concentrations of ozone and its oxidation products were 7.0 ppb and 24.6 ppb in residences, 12.5 ppb and 19.3 ppb in schools, and 12.7 ppb and 19.1 ppb in offices, respectively. Overall exposures averaged 10.9 ppb for ozone and 26.9 ppb for oxidation products, with oxidation product exposures exceeding ozone exposures across all age groups. Residences contributed 58.2% of ozone and 82.6% of oxidation product exposures due to lower air change rates and prolonged occupancy. These results highlight the significant role of residences in exposure, particularly for the elderly, and underscore the need for targeted indoor ozone mitigation strategies to protect public health.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"32 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144083396","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}

Seasonally recurring resource subsidies are common in nature and may influence variations in recipient consumers' life-history traits. In this study, we experimentally demonstrated that terrestrial invertebrate subsidies occurring early in the growing season facilitated consumer individuals to adopt fast growth. In contrast, fewer consumer individuals adopted fast growth when subsidies occurred late in the growing season. Consumer individuals that adopted fast growth matured early at age 1, suggesting that the observed variation in life history emerged along with a fast–slow life-history continuum. The estimated survival probability was lower in consumer individuals from the faster growth cluster in the no-supply treatment (control), suggesting a growth–survival trade-off. However, the growth–survival trade-off became unclear in the early-supply treatment and even reversed in the late-supply treatment. As a result, the frequency of consumer individuals maturing at age 1 was higher in the early-supply treatment than in the late-supply treatment and no-supply treatment, implying a higher short-term population growth with the early subsidies.

However, the effects of glyphosate-based herbicides (GBHs) on this adaptive mechanism remain unclear. To explore, we conducted a cross-design experiment on lizards (<em>Eremias argus</em>) under normal and elevated temperatures, with or without GBH exposure. We assessed maternal reproductive output, egg composition, embryo hatching performance, and the morphological and performance traits of offspring which were uniformly reared under warming regime. Under warming conditions, female enhanced reproductive output by reducing relative clutch mass and increasing egg-laying frequency. They also helped offspring adapt to warmer environments via maternal resource transfer, likely by the observed increases in unsaturated fatty acids and amino acids in eggs. Hatchlings from the warming treatment groups exhibited higher survival rates, underscoring the potential of maternal effect in thermal adaptation. GBH exposure in a warming environment led to reduced reproductive frequency, lower hatching rates, smaller hatchlings and decreased offspring thermal tolerance, diminishing the benefits of maternal effect. These effects may be linked to reduced levels of nucleotide metabolism-related substances, triglycerides, proline, and citrulline in eggs. Our study revealed the adverse effects of GBH on lizards and provided new insights into the impact of chemical pollutants on biological adaptability in the context of climate change.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"42 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144083389","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}
