Surface and subsurface soils from mulched (watermelon) and unmulched (rice) fields were analyzed for MP abundance, morphology, polymer composition, and trace elements. Microplastics were identified using Attenuated Total Reflectance-Fourier Transform Infrared Spectroscopy (ATR-FTIR), and metals were quantified via Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES). Scanning Electron Microscopy with Energy Dispersive X-ray Spectroscopy (SEM-EDS) confirmed elemental associations on MP surfaces. Risk was assessed using the Polymer Hazard Index (PHI), Pollution Load Index (PLI), Geoaccumulation Index (I_geo), and Potential Ecological Risk Index (PERI). Results showed higher MP concentrations in surface soils and mulched fields, with polyethylene (PE) as the dominant polymer. Most MPs were 0.1-0.3 mm (49-50%) or 0.3-1 mm (40-47%) in size. Films were the most common type (61%), followed by fibres and fragments, with fibres dominating deeper layers. Transparent MPs were the most abundant, followed by blue, white, and black. The Polymer Hazard Index (PHI) indicated high risk. The Coefficient of Microplastic Impact (CMPI) showed a moderate impact, while the Pollution Load Index (PLI) values for MPs indicated low to moderate pollution, with particularly elevated levels in mulched soils. The Potential Ecological Risk Index (PERI) classified risk levels as low to moderate, with higher values also observed in mulched fields. Among trace elements, the concentration followed the order: Fe > Zn > Mn > Cr > Pb. While PLI and I_geo suggested low to moderate contamination, PERI indicated low ecological risk. These findings highlight how plastic mulching increases MP accumulation and alters metal dynamics in soil. The co-occurrence of MPs and metals raises concerns for soil health and food safety. Sustainable land management and regular monitoring are critical to mitigate long-term risks.</p>","PeriodicalId":11759,"journal":{"name":"Environmental Geochemistry and Health","volume":"47 10","pages":"436"},"PeriodicalIF":3.8,"publicationDate":"2025-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145058444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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, evidence suggests that current biodegradability standards may not reflect in-field conditions, leading to potential accumulation of biodegradable PMFs in soil with yet undetermined effects on soil microbial communities. We therefore conducted a field experiment to investigate the above and below ground degradation of one conventional and seven biodegradable PMF blends in a temperate climate (UK) over 12 months. We found that PMFs had no effect on soil properties and a negligible effect on microbial community structure. The main factors driving change in relative abundance of bacteria and fungi were exposure time, followed by the potential of meso- and macrofauna interactions. PMFs buried in soil showed no sign of fragmentation, regardless of presence of meso- and macrofauna, which was likely the cause for no overall difference in microplastic concentrations. The slow degradation of all PMFs combined with the lack of physical fragmentation under natural conditions, indicates that degradation is slower than expected according to current biodegradability standards. This highlights the importance of reframing standards by treating degradation as a system property, influenced by a variety of environmental and intrinsic factors.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"72 3 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145059646","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 this study, Fragstats and the HQ module of InVEST were employed to evaluate LULC change effects on landscape patterns and HQ in the Qinhe River Basin (QRB), a critical transition zone between the Loess Plateau and the North China Plain with vigorous implementation of the Grain for Green Program, utilizing the XGBoost-SHAP method to identify the key drivers of HQ. Key findings reveal that during 1990–2022, LULC transitions were characterized by a 9.32 % increase in forest, alongside a 6.09 % reduction in cropland and 6.39 % decrease in grassland, establishing forest as the dominant cover type. Landscape patterns showed reduced fragmentation, with concurrent increases in aggregation, connectivity, and simplification. Over 33 years, 54.6 % of the basin achieved statistically extremely significant improvement, with substantial decline reduction in habitat degradation. HQ enhancement was strongly correlated with cropland/grassland-to-forest conversion. Notably, the XGBoost-SHAP framework uncovered that HQ spatiotemporal variations were jointly driven by natural and anthropogenic factors, with land use intensity and elevation as the main contributing factors. This method further revealed nonlinear relationships: land use intensity exerted a significant negative impact, while elevation, vegetation coverage, and slope showed positive effects with threshold-dependent influences.

This study assesses the effectiveness of landscape-scale participatory governance in reducing fire hazard and enhancing carbon storage. We analysed fire behaviour and carbon balance under four fuel management scenarios: control unmanaged, public intervention, private intervention (led through the MOSAICO initiative), and a mixed governance model. The study was conducted in two counties of western Spain using fire simulations (FLAMMAP) and carbon models under four representative weather scenarios. All treatments significantly reduced fire size conditional burn probability, conditional flame length and crown fire probability, with the mixed scenario being the most effective under extreme conditions. At the local scale, agricultural and livestock practices were particularly effective, especially when spatially coinciding with historical ignition areas. In terms of carbon, the mixed governance scenario resulted in the most favourable net carbon balance by combining lower carbon removals with substantial reductions in potential emissions from wildfires. In contrast, forestry interventions frequently removed large amounts of biomass in areas with a low burn probability, which required longer recovery periods to compensate for carbon losses. Promoting fire-smart landscapes through community-based agroforestry and livestock practices offers a cost-effective approach to mitigate wildfire hazard and, simultaneously, support ecosystem services, including carbon storage. These results underline the urgent need to encourage proactive, community-based land use practices, which simultaneously reduce wildfire risk and enhance ecosystem services such as carbon storage, especially in fire-prone rural areas.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"394 ","pages":"Article 127308"},"PeriodicalIF":8.4,"publicationDate":"2025-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145057323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Developing green technologies to recover silver from secondary sources can alleviate environmental risks induced by waste accumulation or improper disposal while mitigating primary resource scarcity. Conventional recycling methods suffer from high reagent/energy consumption, severe secondary pollution, and ineffective treatment of low-grade resources. Leveraging the polymetallic nature of waste-streams, we apply micro-galvanic selective leaching and pulsed electrodeposition for efficient, green and energy-saving silver recycling. Firstly, multi-metals form a micro-galvanic network in HNO₃, enabling metallic selective leaching by galvanic corrosion under relatively low operational intensity with leaching efficiencies over 95%. Subsequent pulsed electrodeposition (transient potentiostatic excitation alternating with prolonged relaxation) achieves 98.98% silver recovery efficiency from low-concentration leachate. Mechanistic studies reveal that the pulsed potential strategy maintains sustained interfacial reaction activity and efficient kinetics by alternately activating electrochemical/chemical reduction process. The proposed process is expected to reduce CO₂ emissions by 46.7 t/t waste, conserve 38.11% of energy consumption, lower environmental toxicity by 121%, and generates a net profit of $5992.3/t waste-streams. It delivers an efficient and energy-efficient strategy for metal recycling from low-grade resources and contributes to the circular economy.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"20 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145056845","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}
