Here, by integrating genome-resolved metagenomics and metatranscriptomics, we characterized the genomic potential and transcriptional activity of ARGs and MRGs in the gut microbiome of mice exposed to Sb(III)- and Sb(V)-contaminated drinking water. We found that both Sb(III) and Sb(V) significantly increased ARGs abundance, whereas only Sb(III) enhanced ARGs transcription (288.40 ± 41.67 TPM, <em>P</em> &lt; 0.05). Co-selection of ARGs and MRGs was observed through metagenome-assembled genomes (MAGs) analysis, and key taxa driving this process were identified (e.g., <em>Eubacterium_J</em> and Lachnospiraceae_<em>COE1</em>). Sb(III), but not Sb(V), induced co-regulation of macrolide-lincosamide-streptogramin resistance genes and <em>arsRABC</em> operon. A potentially higher risk of ARG dissemination under Sb(III) stress was suggested by the increased abundance and transcription of mobile genetic elements (MGEs).

To support their work under the WFD, we developed VERBER for surface waters, a GIS-based model for pesticide risk assessment and management. VERBER predicts average concentrations of active substances originating from arable fields at the outlet of sub-catchments in inter-connected networks of lakes and water-courses in Sweden. The modelling approach combines a parsimonious steady-state mass balance model with a classification tree trained on Swedish environmental monitoring data, to estimate the fraction of an applied pesticide lost to surface waters based on hydrological characteristics of soils, pesticide properties and application season. According to VERBER model runs for seven active substances (either priority substances in the WFD with particularly hazardous properties or river basin-specific pollutants) at the national scale, 2.2% of sub-catchments in Sweden are at risk of being affected by pesticide concentrations that constitute chronic toxicity to aquatic organisms. A comparison between average surface water concentrations predicted by VERBER and measured concentrations of the seven active substances and two additional substances that often exceed the EU drinking water limit value (0.1 μg L⁻¹) indicated that the model predictions are generally realistic, although it does also seem to be conservative in a few cases.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"417 ","pages":"Article 130883"},"PeriodicalIF":9.2,"publicationDate":"2026-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148943851","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}

Many studies report positive effects of AFH on soil organic carbon (SOC) stocks, yet outcomes remain variable. The factors controlling SOC dynamics under AFH, particularly management practices, therefore must be better understood. We quantified C stocks in soils (0-20 and 20-50 cm), tree biomass, litter and woody debris across 36 AFH located in Southern Quebec (Canada), and compared them with adjacent croplands. These AFH varied in age (5-46 years), tree composition, soil texture and mulch type (none or limited vs. continuous plastic strip). SOC stability was assessed through physical size fractionation into mineral-associated organic matter (MAOM) and particulate organic matter (POM). Contrary to expectations, SOC stocks in the whole profile (0-50 cm) were slightly lower (−6.4 ± 3.9%; mean ± SE) under AFH compared to adjacent fields, due to losses (−13 ± 4%) in the subsoil. These losses were not observed in more developed AFH, suggesting a gradual recovery over time. In the topsoil, SOC increased (+24 ± 5%) in the absence of continuous plastic strips, but decreased (−12 ± 5%) when strips were present. The labile POM fraction accounted for most SOC accrual under AFH (+67 ± 14% relative to controls without plastic strip in the topsoil), while MAOM declined across all layers. Despite these soil responses, total C stocks increased by 21 ± 7 Mg C ha⁻¹ in AFH, mainly due to tree biomass. Biomass C sequestration peaked at 3.7 Mg C ha⁻¹ yr⁻¹ 23 years after plantation. Our results highlight that management practices during AFH establishment can strongly influence SOC dynamics and that plastic mulch may offset potential SOC gains, even though overall C sequestration remains positive due to tree biomass accumulation.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"417 ","pages":"Article 130930"},"PeriodicalIF":9.2,"publicationDate":"2026-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148981721","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}

Both coated urea treatments substantially suppressed NH₃ losses relative to CU, with PCF achieving consistent reductions of 72.3%–92.8% and SCF showing more variable reductions of 28.8%–89.7%. However, sustained nitrogen release from coated urea concurrently stimulated N₂O production, with increases of 8.3%–114.3% under PCF and 15.5%–88.9% under SCF. Critically, NH₃ mitigation substantially outweighed the N₂O penalty, enabling PCF to reduce the combined NH₃ and N₂O losses by 39.8%–69.5% and yield-scaled losses by 45.9%–70.9%, respectively, while enhancing crop yield by 4.7%–11.2%. Soil enzyme assays and metagenomic analyses suggested that NH₃ suppression was associated with reduced urease activity and enrichment of archaeal ammonia oxidation and downstream nitrification genes under PCF, whereas elevated N₂O emissions were correlated with sustained soil inorganic nitrogen replenishment that appeared to override concurrent declines in denitrification genes. These findings suggest that PCF reduces the combined NH₃ and N₂O losses while sustaining crop productivity, although the N₂O penalty outweighed the climate benefit of NH₃ mitigation in three of four years.

The modification aimed to introduce hydrophobicity to the UiO-66 surface, thereby improving conformational structure of the enzyme and enhancing its interaction with the support.

A high TYL degradation efficiency of 99.9% was achieved even at a low PMS concentration (15 mg/L). The activation of PMS by NPBC involves Fe⁰ oxidation and Fe²⁺/Fe³⁺ redox cycling, as well as electron transfer from N components to PMS. Both non-radical pathways (primarily ¹O₂ and electron transfer) and radical species (mainly ^•OH and O₂^•−) contributed to TYL degradation, with the former playing a relatively more important role. Three potential TYL degradation pathways were proposed, differing primarily in the sequence of amino sugar detachment and lactone ring opening. Pathways I and II began with sugar loss followed by ring opening, whereas Pathway III started with ring opening prior to sugar detachment. Ecological toxicity assessment indicated a reduction in overall toxicity when TYL was degraded to products typically found at environmental levels. Molecular docking analyses suggested that the transformation products exhibited reduced antibacterial activity and a lower potential for promoting antibiotic-resistant bacteria.

We conducted interviews to follow up on the results of the PM campaigns. While PM offers a tool to foster wildfire adaptation pathways at the local level, it depends on facilitation and is challenged by social fragmentation, lack of geospatial skills, and inconsistent policy environments.

This model offers a holistic framework for assessing the damages of invasive species and enables the value of a biosecurity system to be conceptualised and estimated in terms of the damages that it avoids or mitigates.

Results indicate that, with the terrestrial border biosecurity system in place (at a cost of AUD$10.45 billion), Australia can avoid approximately AUD$314 billion in present value damages over 50 years, reflecting a significant return on investment. In addition, the model can contextualise the economic damage caused by individual invasive species within a species-co-occurring framework, providing estimates of economic damages for specific species across different time steps.
