However, there is a lack of scrutiny on their combined effect and dietary uptake in marine ecosystems. Therefore, the current study assessed the toxicity of ThP in the presence of MFs on the marine diatom <i>Chaetoceros</i> sp. and evaluated its effects on dietary exposure from <i>Chaetoceros</i> sp. to the crustacean <i>Artemia salina</i>. Liquid chromatography–mass spectrometry results revealed that the uptake of ThP was reduced in <i>Chaetoceros</i> sp. in the binary mixture due to the reduced bioavailability of ThP in the presence of MFs. However, the combination of MFs with ThP showed more reduction in cell viability of <i>Chaetoceros</i> sp. than ThP-single exposure. Abbott’s mathematical model revealed an additive mode of toxicity for the mixture group. X-ray photoelectron spectroscopy results revealed that the mixture of MFs with ThP exhibited the highest reduction in silica content in the diatom biosilica cell wall. The pollutant mixtures impaired the photosynthetic activity, triggered oxidative stress, and reduced the diatom cell viability. Notably, dietary exposure experiments revealed that ThP (0.5 and 1 mg/L) in the absence of MFs exhibited a significant uptake in <i>Artemia salina.</i> However, no significant uptake of ThP was observed in <i>Artemia salina</i> when fed with the binary mixture pre-treated diatoms. Consequently, only the diatoms pre-treated with ThP in the absence of MFs significantly affected the neurotransmitter activity in <i>Artemia salina.</i> This may subsequently have resulted in enhanced reactive oxygen species production, malondialdehyde levels, and mortality. Overall, this study highlights the propensity of MFs in modulating co-contaminant toxicity and dietary uptake in marine organisms.</p></div>","PeriodicalId":546,"journal":{"name":"Environmental Sciences Europe","volume":"38 1","pages":""},"PeriodicalIF":7.1,"publicationDate":"2026-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1186/s12302-026-01481-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148987040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

This review synthesizes the emerging role of wastewater as a mirror of community health and a driver of microbial and resistome restructuring across environmental compartments. Wastewater systems harbor diverse biological and chemical markers, including pathogens, antimicrobial resistance genes (ARGs), pharmaceuticals, and nutrients, reflecting dynamic population health, agricultural practices, and socioeconomic activities.

In Sweden, however, the permitting process remains slow, fragmented, and heavily dependent on document-based workflows, despite the fact that many permitting decisions rely on inherently spatial information such as protected areas, hydrology, biodiversity, land-use constraints, and environmental monitoring data. At the same time, recent national reform proposals (SOU 2024:98) emphasise the need for improved digitalisation, interoperability, and more structured use of environmental information in permitting procedures. This paper presents a conceptual GIS-integrated framework for environmental permitting, using the Swedish system as a case study. The study combines a structured literature review, document analysis, workflow analysis, and geodata inventory to identify spatial data requirements across different stages of the permitting process and to analyse fragmentation within the current geodata ecosystem. Based on this analysis, the paper proposes a GIS-enabled permitting architecture linking spatial datasets, geospatial analysis functions, and regulatory decision points throughout the permitting workflow. The framework is further supported through expert-based plausibility validation involving GIS and spatial-data specialists representing applicant-side, municipal, and international geospatial perspectives. The analysis and expert interviews suggest that GIS already plays an important role in environmental assessment and planning processes but remains insufficiently integrated into formal permitting workflows, where spatial information is often reduced to static map attachments and PDF documents. The analysis also highlights key implementation challenges related to fragmented data governance, interoperability, metadata quality, and access to authoritative spatial services. Rather than proposing a fully implemented system, the paper contributes a conceptual and methodological foundation for future digital permitting architectures. The study proposes that GIS could function as a foundational integration layer with the potential to support more transparent, efficient, and interoperable permitting workflows, while also supporting future extensions involving AI-based decision support, knowledge graphs, and spatially enabled environmental compliance monitoring.</p></div>","PeriodicalId":546,"journal":{"name":"Environmental Sciences Europe","volume":"38 1","pages":""},"PeriodicalIF":7.1,"publicationDate":"2026-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1186/s12302-026-01479-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148752126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Drift and dissipation are key processes determining the environmental presence of CUPs, yet field-based evidence of their fate is limited. This study aimed to provide best-case real-world drift and dissipation values after simultaneous application of one insecticide (pirimicarb) and three fungicides (bixafen, fluopyram and prothioconazole) in winter cereal fields. Application was performed under agricultural best practices, including the use of 90% drift-reducing technology and best-case weather conditions. Relative drift deposition into adjacent meadows was assessed using Petri dishes and environmental samples (bare topsoil, covered topsoil and vegetation) at distances of 1, 5 and 20 m downwind of the treated fields. Dissipation was monitored for up to 128 days. Residues were analysed via high-performance liquid chromatography coupled with tandem mass spectrometry (HPLC–MS/MS). Dissipation was also evaluated with a model named MITAS (MIxture Toxicity of Application Spray series) and measured residues were compared with literature values.</p><h3>Results</h3><p>Under a best-case application scenario, measured relative drift deposition rates exceeded benchmark values in environmental samples (topsoils and vegetation) in some cases, but not in Petri dishes. Environmental samples additionally contained residues of pesticides not applied during the experiment, demonstrating cumulative off-field contamination from other nearby sources. Dissipation in in-field soils was faster than literature-based DT<sub>50</sub>. Although the investigated fields differed in soil type, no substantial differences in dissipation were observed. Dissipation in vegetation samples was in line with literature. Off-field samples showed substance-specific dissipation patterns and were often slower or not detectable.</p><h3>Conclusion</h3><p>Overall, our results indicate that off-field transport of current-use pesticides may occur even under agricultural best practice with drift reducing technology and optimal conditions. Moreover, concentration decrease in environmental samples may be influenced by additional atmospheric inputs, which can complicate the distinction between applied and background-derived CUPs. This highlights that environmental compartments integrate multiple exposure pathways, including direct drift deposition and diffuse environmental sources. Consequently, regulatory approaches may not fully capture the complexity of real-world exposure scenarios. Field-based measurements incorporating landscape-based exposure scenarios therefore remain essential to complement regulatory modelling approaches and to ensure that environmental risk assessments adequately reflect real-world exposure scenarios.</p></div>","PeriodicalId":546,"journal":{"name":"Environmental Sciences Europe","volume":"38 1","pages":""},"PeriodicalIF":7.1,"publicationDate":"2026-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1186/s12302-026-01478-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148613876","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Over the years, bees have become one of the most widely used model organism and biological sentinels due to their ability to bioaccumulate contaminants and, thus, to reflect the state of the ecosystem. Despite this, little is known about the ecotoxicological effects of chemical pollutants on bee species. This review synthesizes current knowledge on the use of bees as an eco-bioindicator of air quality and the resulting ecotoxicological effects of pollutants on these organisms. It also proposes an integrated conceptual framework linking biomonitoring, ecotoxicological assessment, PM, and urban environmental pressure. Specifically, we performed an extensive literature review by investigating multiple databases following rigorous criteria as defined by the PECO framework. As a result of the review process, we selected 38 articles adopting bees as indicators of air contamination presence distribution and 15 investigating bees' response to air pollutants. The selected articles analysed different bee species that showed distinct levels of sensitivity to PM although the western honeybee (<i>Apis mellifera</i>) was the most widely studied. Most of the studies focused on the bioaccumulation of PM₂.₅, pesticides, and heavy metals. Studies on bee response have observed pesticides as the primary cause of mortality and social behaviour effects. The present review shows an increasing rate of publications in the past few years regarding the use of bees as bioindicators. Despite that, it is still necessary to develop standards and protocols that take into account the different sensitivity among pollinators, the actual concentrations of pollutants present in nature, and their effects (single and combined) on biota.

Although numerous studies address machine learning (ML), there is a lack of comprehensive research on how ML practically overcomes these challenges. To fill this gap, this review categorizes ML capabilities into functional themes. Following PRISMA guidelines, this study synthesizes 86 peer-reviewed articles (2014–2026), prioritizing specific operational gains over general accuracy claims. For instance, random forest reduced RMSE by 60.1% compared to linear models, improving prediction accuracy. Moreover, ML models handle 50–70% missing data in time series reconstruction. To address data scarcity, transfer learning leverages knowledge from data-rich regions to enhance prediction efficiency (NSE) in data-poor regions by 7–17%. Unsupervised ML also excels at identifying hidden pollution sources through chemical fingerprinting, without prior labeling. Concurrently, feature ranking significantly lowers monitoring costs by reducing necessary variables from 13 to just 4, while maintaining robust prediction accuracy and enhancing model generalizability. Building upon these capabilities, integrating ML with IoT frameworks enables highly effective early-warning management, achieving up to 99.8% accuracy in real-time anomaly detection. Despite these advancements, the review carefully addresses technical risks such as overfitting and overestimation, emphasizing that continuous human oversight remains essential. The findings also revealed that no one-size model fits all scenarios, as predictive performance depends on data nature, sample size, model architecture, and environmental conditions.
