We referenced our simulations to median river discharge data and phosphorus inputs from point (1,900 wastewater treatment plants) and diffuse sources, determined with the MoRE model and CORINE land cover analysis. We found distinct spatial eutrophication patterns across the river network and complex responses to local and cumulative anthropogenic nutrient emissions. Lower stream orders, particularly those in urban and agricultural areas, showed the highest dissolved phosphorus concentration and benthic algae density. Conversely, pelagic algae dominated higher stream orders, influenced by nutrient transport from lower-order streams to downstream reaches. The validated CⁿANDY model effectively identified eutrophication hotspots, enabling prioritized nutrient and eutrophication management. Although extensive monitoring data were available, systematic gaps in established monitoring schemes limited the model calibration and validation.

Understanding the mechanisms by which drought affects ecosystems under different hydrogeological conditions is crucial for ecosystem protection. The aim of this study was to investigate the characteristics and mechanisms of propagation from meteorological drought (MD) to agricultural drought (AD) and ecological drought (ED) in the Jinsha River Basin from 2000 to 2014. The monthly standardized precipitation evapotranspiration index (SPEI), soil moisture index (SSMI), normalized difference vegetation index (SNDVI), and solar-induced chlorophyll fluorescence (SSIF) data were used to investigate the responses of AD and ED to MD. On the basis of the maximum correlation coefficients (MCCs), the differences in the drought propagation times of MD to AD and ED were explored in positively and negatively correlated areas. A random forest algorithm was used to identify the impacts of climatic factors driving drought propagation. The results revealed that AD was mainly positively correlated with MD, whereas the correlation coefficients between ED and MD ranged from negative to positive. The propagation time from MD to AD was relatively short in summer and autumn. In positively correlated areas, the propagation time from MD to ecological drought indicated by NDVI (EDndvi) was longer than that indicated by SIF (EDsif), and the opposite was true in negatively correlated areas. The random forest algorithm results indicated that temperature (T), solar radiation (S) and precipitation (P) were key factors influencing ED in positively correlated areas and that T was an important factor in controlling the occurrence of ED in negatively correlated areas. Solar-induced chlorophyll fluorescence (SIF) was more sensitive to MD and had a shorter response time in positively correlated areas, suggesting its potential for monitoring vegetation growth responses to drought. We found that MD was not the main factor influencing vegetation growth in negatively correlated areas. The findings of this study had significant implications for understanding the mechanisms of the response of vegetation growth to MD and offered scientific guidance for maintaining terrestrial ecosystem health.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"383 ","pages":"Article 125445"},"PeriodicalIF":8.0,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143874133","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}

Initial mobile air monitoring in mid-February 2023 revealed unique spatiotemporal patterns for a range of volatile organic compounds (VOCs). To determine long-term impacts on air quality, two follow up mobile air monitoring campaigns were carried out in March and April 2023 on public roadways using a proton transfer reaction time-of-flight mass spectrometer. This study aimed to characterize VOC distributions, identify hotspots, and characterize potential hazards. Concentrations of targeted VOCs benzene, toluene, and xylenes were lower overall in East Palestine in April compared to March. Overall, more compounds (<i>n</i> = 48) were identified using non-targeted analysis (NTA) in East Palestine in March compared with April (<i>n</i> = 30). Several of these VOCs were uniquely identified during March sampling, and among the commonly detected compounds, higher average concentrations were observed in East Palestine compared background levels. Spatial analysis revealed similar patterns of hotspots for benzene and additional VOCs identified from NTA, including C₃H₄O, C₄H₈O, and C₆H₁₂O. Using the EPA Hazard Comparison Dashboard, 49% and 40% of the identified VOCs were classified as “very high” or “high” hazards for eye and skin irritation, respectively. Notably, eye and skin irritation were among the common symptoms reported by the residents near the disaster site. Additionally, 29%, 18%, and 14% of the identified VOCs were classified as “very high” or “high” hazards for genotoxicity/mutagenicity, acute inhalation toxicity, and acute dermal toxicity, respectively.

To address the recent progresses in air quality modelling, we conduct a literature review focusing on air quality forecasting models and reanalysis datasets.</p><h3>Recent Findings</h3><p>First of all, the implementation of three-dimensional adaptive meshes/horizontal resolution-variable grids in air quality models offers a crucial insight on multi-scale simulations down to the hectometre level. These models balance high accuracy with computational efficiency. Secondly, current reanalysis still has limitations in its horizontal resolution (dozens of kilometres) that are insufficient to support the analysis and management of air pollution at factory levels or neighbourhood scales. The development of adaptive mesh resolution method provides a promising way to deal with this issue and allows the construction of the chemistry reanalysis at ultra-high resolutions (&lt; 1 km). However, the use of adaptive mesh method in data assimilation is currently still restricted to the column-based one-dimensional models. Thirdly, the application of graphics processing units to air quality predictions enables more optimised resource usage and enhances model performance through hardware acceleration effects, while machine learning methods can both maintain the consistency with numerical solutions and increase the accuracy of air quality predictions for specific chemical species. Furthermore, parameters that describe more complicated processes and mechanisms have been added into pre-existing physical and chemical parameterisations to enable more accurate representation of various small-scale features, such as the parameterisation of inorganic chemistry on the surface of aerosols, as well as various photolysis schemes.</p><h3>Summary</h3><p>The increase of resolution brings computational burdens and shifts the boundary of resolved and sub-grid phenomena in air quality prediction, which in turn stimulates the development and usage of new technologies (e.g. adaptive mesh techniques, graphics processing unit acceleration, machine learning methods). They are conducive to the improvement of prediction accuracies and the acquisition of new insights on atmospheric physical and chemical mechanisms. However, new challenges also ensued, including the selection criteria for mesh refinement, the acquisition of high-resolution observational data and the integration of artificial intelligence-hybrid air quality models. More efforts are required to develop the adaptive irregular mesh grid data assimilation method to overcome the resolution problems of current chemical reanalysis.</p></div>","PeriodicalId":528,"journal":{"name":"Current Pollution Reports","volume":"11 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40726-025-00355-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143877685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Intriguingly, the work also suggests an eCO&lt;sub&gt;2&lt;/sub&gt; stimulation of compensatory mechanisms that allow maintenance of plant P nutrition despite the reduction of plant available P in soil. The authors argue that these findings necessitate a reassessment of whether agricultural nutrient availability tests will be fit for purpose in a high CO&lt;sub&gt;2&lt;/sub&gt; future, and suggest a recalibration of such measurements. Furthermore, the findings of Beechey-Gradwell et al. (&lt;span&gt;2025&lt;/span&gt;) have parallels with recent eCO&lt;sub&gt;2&lt;/sub&gt; studies on P-limited ecosystems (e.g., Keane et al. &lt;span&gt;2023&lt;/span&gt;; Jian et al. 2024) that suggest eCO&lt;sub&gt;2&lt;/sub&gt; reduces plant-available P, likely through stimulation of microbial immobilisation of P, with consequences for ecosystem productivity and its feedback to climate regulation.&lt;/p&gt;&lt;p&gt;As atmospheric CO&lt;sub&gt;2&lt;/sub&gt; concentrations rise, the stimulation of greater rates of photosynthesis in plants can increase plant productivity and, consequently, increase ecosystem absorption of CO&lt;sub&gt;2&lt;/sub&gt;. Understanding this “CO&lt;sub&gt;2&lt;/sub&gt; fertilization effect” is critical for us to determine how agricultural and natural ecosystems will respond to rising CO&lt;sub&gt;2&lt;/sub&gt;, and to quantify how much the increased sequestration of C can help slow the rise of atmospheric CO&lt;sub&gt;2&lt;/sub&gt; and global warming.&lt;/p&gt;&lt;p&gt;A key constraint to the CO&lt;sub&gt;2&lt;/sub&gt; fertilization effect on plant productivity is the availability of nutrients in soil (Terrer et al. &lt;span&gt;2019&lt;/span&gt;). In the case of agricultural systems that are (co-)limited by soil P availability, phosphate fertilizer may be needed to realize the CO&lt;sub&gt;2&lt;/sub&gt; fertilization benefit. In contrast, should eCO&lt;sub&gt;2&lt;/sub&gt; stimulate immobilization of P in soil, this may limit the effectiveness of the P fertilizer, meaning eCO&lt;sub&gt;2&lt;/sub&gt; could create the need for more fertilizer addition along with the associated costs to farmers and increased environmental risk. The need to understand the interaction between eCO&lt;sub&gt;2&lt;/sub&gt; and P fertilizer application is therefore clear, and this need is heightened given the globally depleting and finite resource of P for use in fertilizers.&lt;/p&gt;&lt;p&gt;To address this, Beechey-Gradwell et al. (&lt;span&gt;2025&lt;/span&gt;) investigated P fertilizer and eCO&lt;sub&gt;2&lt;/sub&gt; effects on a species-rich pasture in New Zealand.
