To elucidate the sorption preferences and immobilization selectivity of sulfhydryl grafted palygorskite (SGP), series of experiments including solution sorption, spectroscopic characterization, density functional theory (DFT) calculation, soil incubation, and plant pot cultivation were conducted. Sulfhydryl grafting significantly enhanced SGP's sorption capacities for Cu²⁺, Hg²⁺ and Cd²⁺. The selectivity coefficients determined by the competitive sorption highlighted the sorption preference of SGP towards Fe³⁺, Hg²⁺ and Cu²⁺, but Fe³⁺ was attributable to the palygorskite substrate itself. The sorption selectivity was confirmed by the sorption energies calculated by the DFT. In six model soils, SGP consistently reduced available Cd and Cu contents with the minimum reductions of 35.74 % and 20.93 % respectively, regardless of acid or alkaline soils, while showing no consistent effect on other cations. Correspondingly, SGP decreased Cd and Cu accumulation in pakchoi leaves with the minimum reductions of 40.51 % and 29.67 %, demonstrating selective immobilization. The maximal immobilization efficiency for Cd (5.66 mmol/kg) and Cu (5.37 mmol/kg) quantitatively characterized SGP's preferential selectivity of the immobilization effect in acid and alkaline soils.

Promoting healthy dietary habits and raising awareness are key actions in this shift, with governments playing a significant role through public procurement and food-based dietary guidelines. Specifically, school dietary guidelines can foster sustainable eating behaviors among children. This article examines Catalonia, a North-East Spanish region, where the Public Health Agency (ASPCAT) has issued school dietary guidelines since 2005, updated in 2012, 2017, and 2020. The goal of this study was to assess the progressive changes in the environmental impacts of school menus for children aged 7–12 years following the four versions of ASPCAT guidelines. Additionally, it aimed to identify trade-offs among various environmental metrics, pinpoint food groups contributing most to environmental impacts, and propose strategies to further reduce the environmental impact of school meals. The Life Cycle Assessment (LCA) methodology was applied. Inventories were obtained from Agribalyse v3.2 database, and characterized through sixteen individual environmental indicators and the composite one from the Product Environmental Footprint v3.1 methodology. Results showed a decrease in environmental impacts with each guideline update. Menus aligned with the 2020 guidelines had 23 % lower environmental impacts compared to those based on the 2017 guidelines, and 40 % lower than those based on the 2005 guidelines. All individual environmental indicators showed reductions in 2020 compared to 2005, ranging from 5 % to 52 %. Second dishes, mainly meat and fish, contributed most to environmental impacts. Replacing meat and fish with plant-based proteins, combined with a more diversified cereal intake, could reduce dietary environmental impacts by approximately 50 %. By identifying major contributors and suggesting potential improvements, our findings can contribute to the revision of the guidelines of Spain for healthy and sustainable school meals.</div></div>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"995 ","pages":"Article 180102"},"PeriodicalIF":8.2,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144679655","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}

Winter road salt was identified as the primary driver of plant cover loss: low-tolerance species accumulated excessive sodium and chloride, resulting in chlorotic and necrotic damage even under moderate salinity (median electrical conductivity (EC), 0.31–0.35 mS/cm, as measured in soil–water suspensions).

Over 95 % of these impacts are driven by irrigation, fertilizers, and weed and pest management. Significant differences between treatments underscore the role of crop-specific farming practices. Finger-weeding consistently lowered environmental impact across most conditions, whereas cultivation and flaming generally resulted in moderate to high impacts regardless of fertilizer level.

The untreated control consistently led to the highest environmental burdens, reinforcing the necessity of effective weed management.

To understand how reindeer grazing, coupled with changes in snow depth affects CO₂ exchange, we used recent snow treatments (ambient, reduced, and increased snow depth) combined with 25- and 55-year-old reindeer exclusions and the adjacent grazed areas in boreal and subarctic Scots pine forests that are main winter pastures for reindeer/caribou and cover a significant portion of boreal and subarctic landscapes. At both study sites, we measured understory net ecosystem exchange (i.e., NEE), ecosystem respiration (i.e., ER), and gross ecosystem production (i.e., GEP) over two snow-free seasons. We found that 55 years of reindeer exclusion increased C source strength by 136 % under ambient snow depth and 205 % under reduced snow depth in comparison to the grazed area with respective snow conditions. On the contrary, increased snow depth decreased C source strength inside the exclusion offsetting the difference between reindeer grazing treatments. Our results show that grazing may enhance ecosystem stability to winter climate change in comparison to long-term absence of grazing. This highlights the complexity of climate-grazer interactions in functioning of northern ecosystems which are experiencing variations in snow depth.</div></div>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"995 ","pages":"Article 180089"},"PeriodicalIF":8.2,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144672489","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 the coastal area, significant variations in alcohol consumption were observed, with tourist activity during the summer months being associated with nearly a tenfold increase in alcohol use compared to the winter months. Furthermore, four weekly campaigns were conducted for the determination of five stimulant illicit drugs.
