Using bunching analysis, we find a significant concentration of firms just above the statutory R&D intensity threshold, indicating that some firms strategically adjust their reported R&D expenditure to obtain preferential tax treatment. We then apply a bunching-based difference-in-differences approach to examine how such behavior affects the environmental outcome of the policy. The results show that firms within the bunching interval achieve little reduction in carbon emissions, while firms outside the interval experience a significant decline. Green innovation is the main channel through which tax incentives reduce emissions, but this channel is absent among strategic responders. We also find that non-strategic high-tech enterprises achieve both better economic performance and lower carbon emissions.

The findings reveal that biochar enhances the flowability of OPC pastes but slightly reduces that of LC<sup>3</sup> due to its high surface area and interparticle friction.

This study proposed an integrated analytical framework linking the WEF nexus, ES supply-demand relationships, and land use structure to develop targeted zoning regulatory strategies for Inner Mongolia, China. Five key ESs representing the WEF nexus were selected, including water yield (WY), carbon sequestration (CS), food production (FP), soil retention (SR), and habitat quality (HQ), and their supply, demand, and ecological supply-demand ratio (ESDR) were assessed for 2022. A self-organizing map (SOM) was then applied to classify the study area into six ES balance bundles (ESBBs) reflecting distinct WEF nexus archetypes. Within each ESBB, piecewise linear regression was used to identify critical land use proportion thresholds for maintaining positive supply-demand balances. Results showed that: (1) Inner Mongolia faced significant overall ES deficits and spatial mismatches, with severe shortages in WY and CS.

However, previous studies mainly focused on national-scale assessments, selected river basins, or specific pharmaceutical classes. In this study, we systematically reviewed 226 peer-reviewed articles and compiled 8628 occurrence records for 158 pharmaceutical compounds. A multi-criteria prioritization framework that integrated both hazard and exposure potential was used to identify priority pharmaceuticals across nine river basins. Antibiotics were the most frequently detected class of pharmaceuticals, although most had low or moderate priority scores. Erythromycin, roxithromycin, and azithromycin were notable exceptions and ranked highly. Among nonantibiotic pharmaceuticals, estrone and ibuprofen ranked highly in all nine basins. Beyond these shared priorities, several pharmaceuticals showed distinct basin-specific priority pattern. Psychotropic medicines, including diazepam, fluoxetine, sertraline, and citalopram, were identified as priorities in highly urbanized basins, particularly the Haihe and Yangtze River basins. In the Yellow River Basin, the lipid modulator gemfibrozil was prioritized, while in the Pearl River Basin, the veterinary antibiotic salinomycin was prioritized. Combining the rankings with uncertainty estimates showed that high-priority compounds with low uncertainty should be considered for stringent monitoring and control, whereas compounds with high uncertainty require additional occurrence and toxicity data.

Sediment fingerprinting has therefore been widely applied to quantify sediment provenance. Here, we identified a previously overlooked process, termed Differential Dissolution-Induced Concentration Drift (DDICD), whereby element-specific dissolution during transport induces systematic shifts in sediment geochemical composition. This process implies that post-transport elemental concentrations depend not on absolute elemental properties, but on their relative differences with respect to coexisting elements, potentially challenging the concentration-conservation assumption underlying conventional sediment fingerprinting techniques when DDICD occurs. To address this issue, we developed a theoretical framework for DDICD and formulated a ratio-tracer-based correction approach. Theoretical analyses using synthetic datasets revealed that DDICD intensity was primarily controlled by the heterogeneity of elemental dissolution rates and initial masses, as well as by the rank concordance between these properties, originating within individual sediment sources and accumulating through source mixing to amplify sediment fingerprinting errors. Empirical results from the Yangtze River Basin showed that concentrations of highly soluble elements generally decreased during transport (e.g., Ca and Mg decreased by 15.02% and 8.06%, respectively), whereas relatively insoluble elements generally increased (e.g., Al increased by 6.39%). Sediment unmixing results further indicated that the mean absolute error (MAE) of source contribution estimates increased logarithmically with transport distance and elevation drop. Compared with element tracers, the use of element ratios substantially improved model accuracy and robustness, reducing mean MAE and its standard deviation by 9.83 and 0.45 percentage points, respectively. All these findings provided strong evidence for the occurrence of DDICD in natural river systems and demonstrated its substantial influence on sediment fingerprinting results. Consequently, DDICD should be explicitly considered in sediment fingerprinting of large catchments or regions characterized by intense weathering and abundant carbonate or silicate minerals, as neglecting this process may introduce systematic biases into sediment source apportionment.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"418 ","pages":"Article 131017"},"PeriodicalIF":9.2,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149079240","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}

Remarkably, 29-42% of all analyzed wildfires spread faster at night than during the day, a seldom-reported phenomenon likely due to interactions between surface weather, atmospheric instability and, potentially, pyroconvection. Increases in fire intensity likely facilitated the overwhelming of suppression efforts during simultaneous fire events that may have been manageable decades ago.
