This study provides a unique long-term (2016–2020) and high-resolution investigation of the Münstersche Aa River (Northwestern Germany) focusing on the thorough characterization of input pathways for pesticides, biocides and pharmaceuticals in the catchment with heterogeneous land-use (62 % agricultural and 26 % urbanized). 468 samples were collected using two automated high-frequency samplers and five catchment-wide sampling campaigns providing a comprehensive data set. While the input of pesticides is the major stressor in the agriculturally dominated upper catchment, input of treated wastewater is dominating the water chemistry of the lower catchment, especially during summer low flows (up to 100 % wastewater fraction). Detected pharmaceuticals in the catchment include carbamazepine, diclofenac, metoprolol, phenazone and sulfamethoxazole. Moreover, caffeine as an indicator substance suggests input through non-conventionally treated wastewater. The pesticides chlortoluron (winter) as well as terbuthylazine and 2-methyl-4-chlorophenoxyacetic acid (MCPA) (summer), occur related to their respective application time. Moreover, a belated, accumulated input of terbuthylazine was observed in winter 2019/2020 after an extremely dry period from 2018 to 2019. Urban runoff adds further pesticides such as mecoprop-P while tebuconazole input from both agricultural and urban land-use was identified. Even though detected concentrations are below thresholds for acute toxicity, mixture toxicity could pose risks in the Münstersche Aa. Ongoing climate change is expected to intensify these seasonal patterns in the catchment. Lake Aasee may however function as a sink for OMPs through degradation processes especially during low-flow conditions. This study enhances the understanding of river pollution dynamics in small, mixed land-use catchments and aids targeting the goals of the Water Framework Directive for the Münstersche Aa and other lowland streams with comparable land use.</div></div>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"982 ","pages":"Article 179665"},"PeriodicalIF":8.2,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144070546","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}

Hydrothermal carbonization (HTC) is a green, efficient and clean production technology that converts sewage sludge into solid-phase products (including hydrochar and ash) and liquid-phase products. Hydrochar has potential as a precursor of high-value-added carbon materials, but ash residues limit its application. Air flotation technology uses the differences in the physical and chemical properties of mineral particles to separate them. Owing to the differences between hydrochar and ash, they are expected to be separated by flotation technology. Therefore, this systematic review examines the migration and transformation pathways of sewage sludge components during HTC and discusses the parameters affecting HTC. The optimization of operating parameters (including bubble size, flotation reagent type, and dosage) in the air flotation process is briefly introduced. The key is to propose a coupling technology of HTC and air flotation, which is used to separate hydrochar and ash. Coupling technology provides a new perspective and reference for future research on the high value-added use of sludge, provides innovative references for sustainable organic solid waste disposal and supports the transition to a carbon-neutral future.</div></div>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"982 ","pages":"Article 179655"},"PeriodicalIF":8.2,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144070527","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}

Recycling post-consumer polyethylene terephthalate (PET) bottles into recycled PET (r-PET) fibres for home textiles provides sustainable solutions by extending materials life cycles.

Life Cycle Assessment (LCA) and Life Cycle Costing (LCC) were used to explore the impacts of various energy sources and fibre blends on sustainability outcomes. The system boundary of this study covers collection of post-consumer PET bottles by scavengers, sale to the local crushing plants and their conversion to PET flakes. Pet flakes are then sent to an extrusion facility for conversion into r-PET fibre which is used in the home textiles production. Using a cradle-to-gate approach, SimaPro v9.6 software and the ReCiPe 2016 midpoint methodology was employed to quantify environmental and economic impacts of one tone home textiles. LCA identified human carcinogenic toxicity (105.36 kg 1,4-DCB) as the highest impact, driven by chemical use and transportation, and low global warming (3.43 kg CO ₂ eq) values. LCC estimated total production cost of $28,000/ton, with 39.5 % attributed to dyeing and finishing processes. Substituting heavy fuel oil-generated electricity with solar energy reduced global warming potential by 5–6 %, and a 50:50 blend of r-PET and virgin cotton fibres significantly decreased all impact categories, including a 14 % reduction in water use.

Whereas eutrophication has been linked to nutrient additions in conjunction with human activities, much less is known about water quality trends when nutrient additions persist for centuries or millennia. Here, we used paleolimnological techniques to reconstruct eutrophication and cyanobacteria dynamics in Lake Wauberg, FL, USA, a lake that has experienced millennial-scale nutrient additions from natural phosphate geology. We measured photosynthetic pigments, cyanotoxins, and nutrient concentrations on a sediment core spanning the last ~6900 years. Our primary hypothesis is that the long-term total phosphorus (TP) additions caused constant cyanobacteria dominance throughout the entire history of the lake. Focusing on the last 5 ka BP with constant lake conditions, photosynthetic pigments and cyanotoxins demonstrated a strong positive relationship with TP over other nutrients. By dividing TP inputs into three levels, primary producers positively increased with low TP inputs but showed no change under moderate levels. Under high (2.2–3 mg g⁻¹) and extreme (&gt;3 mg g⁻¹) TP sedimentary concentrations over the last 0.3 ka BP, substantial increases in cyanobacteria abundance, rapid production of microcystins (MCs), and a possible shift to N-fixation occurred. These data show that chronic and additive TP inputs can produce asynchronous responses in the primary producer community and MC concentrations with substantial increases occurring at higher TP thresholds. Linking the historic ecological response to TP periods with current limnological conditions could provide new directions in forecasting and managing aquatic ecosystems that experience chronic TP inputs.</div></div>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"982 ","pages":"Article 179625"},"PeriodicalIF":8.2,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143948020","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}

In Breede Valley Municipality, Western Cape, South Africa, weekly monitoring of wastewater treatment plants (WWTPs) showed consistently high SARS-CoV-2 viral loads in Rawsonville, especially of the Delta variant (AY.32 and B.1.617.2), despite Omicron's dominance in other regions.

In contrast, the manhole near public toilets (RV_P, 470 gc/mL) had the lowest viral load.
