As the Loess Plateau is a typically erosion-threatened region, determining the spatial matching pattern and drivers of SCS supply (soil conservation) and demand (soil erosion) is essential for sustainable development and effective resource management. This study innovatively proposed the coupling coordination framework between SCS supply and demand to assess the current state and clarify the subsequent regulation direction. First, the RUSLE model was employed to evaluate the SCS supply and demand from 1990 to 2020 and acquire the ecological supply-demand ratio (ESDR). Then, the SCS supply-demand coordination relationship was spatially quantified by utilizing the coupling coordination degree (CCD) model, and a function fitting was performed between ESDR and CCD. Using the geo-detector model, the Getis-Ord Gi^⁎ method, and the local Moran's I index, the influences of natural, engineering, and socio-economic factors on the SCS supply-demand coordination were explored from global and local perspectives. The results showed that: (1) the annual average supply of SCS increased by 64.93 % in 1990-2020; the average demand decreased by 52.43 %; the average ESDR increased by 28.06 %; supply surplus was the predominant feature, more conspicuously in the central and eastern regions; (2) the highest supply-demand CCD was captured in the central and eastern regions, showing \"Moderate balance\" and \"High balance\" respectively, and its area increased by 27 % in 30 years; the lowest CCD regions were mainly in the northwest and their area shrank; (3) enhancing the supply of SCS and reducing demand facilitated the coordination of the supply-demand relationship, and the threshold for the supply-demand coordination state decreased over time; (4) climate, topography and soil properties dominated the spatially non-stationary change of the SCS supply-demand pattern, followed by engineering measures such as afforestation and terraces, and finally socio-economic factors.

Digital Soil Mapping (DSM) is one of the most conventional and widely used methods for mapping soil. This study introduces a novel strategy for DSM by incorporating the neighborhood effect of environmental covariates (ECs), aiming to enhance mapping accuracy of soil properties. The research focused on modeling organic carbon (OC), cation exchange capacity (CEC), bulk density (BD), and pH in southern Canada using 18 ECs derived from the Soil Landscapes of Canada dataset and satellite imagery. Two strategies were compared: a conventional approach using standard ECs, and a proposed method incorporating neighboring ECs through Inverse Distance Weighting (IDW). Both strategies employed Gaussian Process Regression (GPR) for modeling. Results demonstrated significant improvements in accuracy using the proposed strategy. Mean absolute errors were reduced by 32 %, 36 %, 28 %, and 14 % for OC, CEC, BD, and pH, respectively. The proposed method also decreased the coverage of high-error areas and improved R² values across all soil properties. Moreover, mean uncertainty in soil property modeling decreased by 3.4 % to 3.9 % using the proposed strategy. This study highlights the importance of considering spatial context in DSM through neighborhood effects. The proposed strategy offers a more nuanced and accurate approach to soil property modeling, with potential applications extending beyond soil science to other environmental mapping domains. These improvements in soil mapping accuracy have significant implications for sustainable land management, precision agriculture, and environmental conservation.</p>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"957 ","pages":"177798"},"PeriodicalIF":8.2,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142778891","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 aimed to characterize PFAS concentrations in an environmental justice community impacted by active/legacy copper mining, compounded by wildfires and flash floods. Additionally, the study explored the (re)mobilization of PFAS and co-occurrence with metal(loid)s following these events. Twenty-eight PFAS compounds in 35 residential and 8 control surface soil samples were analyzed via liquid chromatography-tandem mass spectrometry (LCMS/MS). The maximum total PFAS concentration observed in the residential samples was 96.40 μg kg^-1, compared to 1.69 μgkg^-1 in the control samples. Perfluorobutanoic acid (PFBA) had a maximum concentration of 61 μg kg^-1 in residential samples, while Perfluorohexane sulfonic acid (PFHxS) had the highest concentration in the control samples at 0.92 μg kg^-1. Long-chain PFAS were most dominant in this study. Perfluorooctane sulfonic acid (PFOS) (58 % of the samples), Perfluorooctanoic acid (PFOA) (35 %), and Perfluorohexane sulfonic acid (PFHxS) (72 %) exceeded the U.S. EPA Soil-to-Groundwater Risk-Based Screening Levels, highlighting the potential risk of contaminants migrating from soil to groundwater, which could ultimately impact groundwater quality. Co-occurrence analysis showed that increases in PFAS concentrations were positively associated with Zn (β = 1.25, p = 0.0034) and Ba (β = 1.23, p = 0.0284) but negatively associated with Pb (β = -0.83, p = 0.0115) and Co (β = -1.38, p = 0.04671).

About three-quarters of all known human infectious diseases are zoonotic, and potential health impacts of these diseases are higher where infectious disease surveillance and access to health care and public health services are limited. This is especially the case for remote circumarctic regions, where drivers for endemic, emerging, and re-emerging zoonotic diseases include anthropogenic influences, such as pollution by long-range transport of industrial chemicals, climate change, loss of biodiversity and ecosystem alterations. In addition to these, indirect effects including natural changes in food web dynamics, appearance of invasive species and thawing permafrost also affect the risk of zoonotic disease spill-over. In other words, the Arctic represents a changing world where pollution, loss of biodiversity and habitat, and maritime activity are likely driving forward occurrence of infectious diseases. As a broad international consortium with a wide range of expertise, we here describe a selection of case studies highlighting the importance of a One Health approach to zoonoses in the circumarctic, encompassing human health, animal health, and environmental health aspects. The cases highlight critical gaps in monitoring and current knowledge, focusing on environmental stressors and lifestyle factors, and they are examples of current occurrences in the Arctic that inform on critically needed actions to prepare us for the future.

The results demonstrated that DEHP induced significant histopathological alterations in gill tissues, with significant enrichment observed in multiple pathways associated with amino acid, hormone, lipid, and xenobiotic metabolism. Metabonomics-transcriptomics analyses indicated that DEHP-induced significantly over-activation of cytochrome P450 1B1-like (p < 0.001) and cytochrome P450 3A30-like (p < 0.05) via the nuclear xenobiotic receptors pathway was a key factor contributing to the disruption of tryptophan metabolism and steroid hormone biosynthesis, as well as inducing circadian rhythm disruption. Moreover, circadian rhythm disruption further exacerbated the imbalance of cytochrome P450 (CYP450) enzyme system as well as linoleic acid, arachidonic acid, sphingolipid, and glycerophospholipid metabolism. Overall, the feedback regulation between the CYP450 enzyme system and circadian rhythms emerged as the primary mechanism underlying DEHP-induced metabolic and transcriptional disruptions, ultimately resulting in gill toxicity.

Results revealed that PS-MPs induced depression-like behaviors in zebrafish, characterized by reduced exploration, decreased locomotor activity, and altered social interaction. Histological analyses of brain tissue demonstrated PS-MPs-induced neuropathological changes, including perinuclear vacuolation and reduced Nissl bodies. Additionally, PS-MPs triggered neuroinflammation, evidenced by upregulated pro-inflammatory cytokines (il-6, il-1β), and disrupted the circadian rhythm, leading to altered expression of key clock genes (per1b, per2, per3) and cryptochrome genes (cry1a, cry2). Furthermore, PS-MPs exposure significantly altered neurotransmitter levels, decreasing dopamine, serotonin, norepinephrine, acetylcholine, tyrosine, and tryptophan. In vitro experiments using HMC3 microglia cells confirmed that PS-MPs induced microglial activation, morphological changes, and dysregulated gene expression related to inflammation and circadian rhythm.

In the present work, ensemble species distribution models were developed for Bt based on the generalized linear model (GLM), generalized boosting model (GBM), random forest (RF), and maximum entropy (MaxEnt) under two distinct scenarios, SSP2-4.5 (optimistic) and SSP5-8.5 (pessimistic) for the year of 2050, 2070, and 2090. The performance of our models was evaluated based on true skill statistics (TSS) and the area under the receiver-operator curve (AUC) indices. Both AUC and TSS values were observed in an acceptable range, with AUC at 0.84 and TSS at 0.512, respectively. Results indicate that most of the areas currently suitable for Bt will likely remain stable in the future, particularly Central America, Central and South Africa, South Asia, and parts of Oceania. Norway, Peru, and the UK will have notable habitat gains by 2090 based on SSP2-4.5 and SSP5-8.5 scenarios. On the contrary, Serbia, Guinea, Poland, Croatia, Spain and Romania showed notable losses under both scenarios.
