However, there is no standardized approach defining how many data sets should be considered or whether influencing factors such as substance concentration must be included. For pesticides that are primarily degraded microbially, concentration can significantly influence degradation rates. Elevated levels may exert toxic effects on microorganisms, thereby slowing degradation. This is relevant for the fungicide tebuconazole, which has a broad mode of action including antimicrobial toxicity. Within a comprehensive mesocosm study, concentration-dependent degradation of a commercial tebuconazole formulation was investigated. Eight freshwater stream-pond mesocosms containing flow-through and stagnant zones were established and dosed once with 0, 5, 50, 100, 500, 1000, and 5000 μg/L tebuconazole. Over one year, concentrations in water from all systems and in sediment layers of selected treatments were monitored using GC-MS/MS. Dissipation times for water, sediment, and the overall system were calculated using a newly developed hierarchical kinetic model that incorporated concentration as a covariate, alongside standard degradation models with different error models. A clear concentration dependency was observed: dissipation time increased from 176 days at the lowest concentration to 1079 days at the highest. Transfer to sediment was minimal (<5% within one year). Relevant transformation products were detected and partially quantified in water via LC-MS/MS, but their low quantities allowed them to be excluded from kinetic modeling.","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"1051 ","pages":"182286"},"PeriodicalIF":8.0,"publicationDate":"2026-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148890691","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}

Understanding the sources and processes that shape plant ionome is essential for a range of applications, including environmental monitoring, geological mapping, and mineral exploration. The boreal region presents a scenario where the prevalence of allochthonous glacial sediments decouples soil geochemistry from its bedrock source, complicating geological mapping. We investigated the influence of geological and environmental characteristics on the ionomes of Norway spruce, Scots pine, and common juniper in the boreal zone. Samples included bark, twigs, and needles collected from 93 sampling stations across a northern boreal mature forest. Compositional statistical analysis revealed significant effects of edaphic and bedrock properties on conifer ionomes, though responses varied by species and tissue type. Soil moisture and organic matter content strongly influenced cobalt, molybdenum, barium, manganese, but also lead, rubidium, strontium and nickel concentrations. Bedrock geology influenced cobalt, nickel, calcium, magnesium, copper, and lead, detectable even beneath the till cover. A primary challenge lies in determining the specific source for elements originating from both soil and bedrock or mainly one of the sources. Notably, gold‑cobalt mineralisation signals were preserved in Norway spruce bark despite the overlying sediments. These findings demonstrate the utility of conifer ionomes for geological mapping despite complex surficial geology.","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"1051 ","pages":"182098"},"PeriodicalIF":8.0,"publicationDate":"2026-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148890679","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 investigated carbon dioxide (CO2) emissions from abandoned and active mine shafts in the Lowkon and Heipang areas of Plateau State, Nigeria, with the aim of evaluating the influence of meteorological and geochemical factors on gas migration and potential environmental implications. Field monitoring was conducted between August and October 2025, during which CO2 concentration, air velocity, temperature, humidity, and atmospheric pressure were measured at shaft collars (0 m) and above ground level (1 m). The collected soil samples were subjected to geochemical, mineralogical, and organic carbon analyses to evaluate lithological controls and potential gas migration pathways. Regression analysis was applied to evaluate the relationship between abiotic parameters and CO2 flux. The results indicate that CO2 emissions are strongly influenced by subsurface geogenic sources, shaft mineralogy, and atmospheric conditions, particularly wind velocity, while temperature and pressure show comparatively weak influence. CO2 flux values reached 7.94 kg m-2 s-1 in Heipang and 4.94 kg m-2 s-1 in Lowkon, reflecting efficient upward gas transport through fractured and permeable mine structures. The persistent nature of CO2 emission and proximity to residential areas indicate potential long-term exposure risks. The findings highlight the need for systematic monitoring, proper closure of abandoned mine shafts, and the implementation of targeted regulatory policies to mitigate post-mining gas hazards in the Jos Plateau region.","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"1051 ","pages":"182245"},"PeriodicalIF":8.0,"publicationDate":"2026-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148885749","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}

However, the magnitude and direction of the effect of dung beetle presence on dung GHG emissions are not consistent across studies, potentially due to variations in experimental practices. To better understand dung beetles' emission mitigation potential, this study seeks to evaluate how the interactions between dung shape, mass, and dung beetle presence affect dung GHG emissions. A laboratory experiment was conducted to assess the effects of Onthophagus nuchicornis presence, dung shape, and dung mass on dairy cattle dung GHG emissions over a 21-day period. Results revealed that dung mass can significantly impact the effect of dung beetle presence on dung CO2 emissions. The presence of dung beetles in mesocosms containing 100 g dung pats increased CO2 emissions by 29%, while their presence in mesocosms containing the 400 g dung pats increased emissions by 64%. Additionally, the interaction between dung shape and mass, as well as dung shape and beetle presence significantly impacted CH4 emissions. Flattening 100 g dung pats resulted in a 44% reduction in CH4 emissions, while flattening 400 g dung pats reduced CH4 emissions by 13%. Beetle presence in flattened dung pats resulted in a 72% reduction in CH4 emissions, whereas their presence in non-flattened dung pats only resulted in an 8% reduction in CH4 emissions. These findings reveal the importance of methodological decisions when studying the relationship between dung beetle activity and GHG emissions from dung pats.","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"1051 ","pages":"182273"},"PeriodicalIF":8.0,"publicationDate":"2026-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148885739","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}

Leveraging the biological sensor's ability (Tillandsia recurvata) to capture particles, we deployed biomonitoring networks to monitor both outdoor and indoor environments at CH sites over three months and to characterize the magnetic fraction. Micron- and submicron-sized magnetite with spherical and irregular morphologies, co-associated with Cr, Mn, Ni, Cu, and Ba, were detected using magnetic and SEM-EDS techniques. The mean (standard deviation) content of airborne magnetic particles (AMP) decreased from the city center museums to the archeological zone, and from outdoor sites (AMP = 0.12 (0.05) mg) to museums' indoor sites (AMP = 0.06 (0.03) mg).

Raman spectroscopy was evaluated as a rapid, non-destructive approach to resolve these biochemical adjustments. Mature Quercus ilex L. trees were sampled along a well-defined pollution gradient in Tuscany (Italy), spanning high, intermediate, and low levels of NO₂ and PM₁₀. Leaf Raman spectra revealed coordinated modulation of primary and secondary metabolism. Pigment-related bands (chlorophylls and carotenoids) increased toward the most polluted site, while inducible flavonoid signals showed site-dependent variation consistent with oxidative pressure in superficial tissues. These patterns were consistent with destructive biochemical analyses and chlorophyll fluorescence measurements, which indicated acclimation rather than photoinhibition damage. A composite Raman index showed a close site-level association with NO₂ exposure, suggesting that nitrogen-related urban pollution was the main exposure component linked to the observed metabolic response. Overall, Raman spectroscopy captures the chronic metabolic imprint of urban air pollution in Q. ilex, resolving coordinated pigment reinforcement and defensive activation without sample destruction. This approach provides a rapid and scalable framework for linking atmospheric chemistry to plant functional status in biomonitoring applications.","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"1051 ","pages":"182253"},"PeriodicalIF":8.0,"publicationDate":"2026-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148878920","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}

Our study employed stable isotope analysis (δ13C and δ15N) to investigate the importance of seagrass carbon as a source of nutrition to important invertebrates spanning different trophic levels (i.e., planktonic, filter-feeding and grazing) around the island of Mauritius. Isotope mixing models confirmed high levels of assimilation of seagrass carbon across three trophic levels (dietary proportions ranging from: 35% to 95% for zooplankton, 34% to 59% for the urchin Echinometra mathaei and 14% to 34% for the bivalve Pinna muricata). The degree to which consumers relied on seagrass was strongly influenced by site-specific trends in the relative cover and health of seagrass meadows (i.e., dietary importance declined at sites of observed seagrass loss). Thus, seagrass health is directly implicated in the diet of marine invertebrates, many of which are central to artisanal fisheries and the local blue economy. By integrating novel isotopic data and ecological modelling, we show that seagrass meadows in Mauritius exhibit tight trophic coupling with marine prey species underscoring their importance as engines of nearshore productivity and highlight the urgent need for their protection and restoration across the Western Indian Ocean.","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"1051 ","pages":"182208"},"PeriodicalIF":8.0,"publicationDate":"2026-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148878944","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}
