To simulate Daihai's topography and compare the driving mechanisms of the lake area and water storage (WS), this study utilized Extreme Gradient Boosting (XGBoost) to correct the Digital Elevation Model (DEM) of the lake. Subsequently, the Long Short-Term Memory (LSTM) neural network model was utilized to delineate the topography of Daihai, constructing a time series of WS from 1990 to 2022. Furthermore, the Random Forest was used to assess the impacts of the de Martonne Aridity Index, Precipitation Intensity, Surface Water Resource Utilization (SWU), and Groundwater Resource Utilization (GWU) on Daihai's area and WS from a watershed perspective. The results demonstrate that, based on the corrected DEM, the LSTM model's terrain prediction accuracy (RTK mean absolute error MAE=0.71 m) is much higher than that of the simple bowl-shaped model (MAE=6.23 m) and XGBoost (MAE=1.41 m). From 1990 to 2022, SWU contributed 0.58 and 0.75 to the shrinkage of Daihai's area and WS, respectively, while GWU contributed 0.38 and 0.22 to the shrinkage of area and WS, respectively. Compared to WS, during the shallow water shrinkage stage, the area tends to overestimate the primary factors and underestimate the secondary factors. In contrast, during the deep water shrinkage stage, it underestimates the primary factors and overestimates the secondary factors. Exploring the causes of lake shrinkage from the perspective of WS allows for a comprehensive consideration of the impact of topography on lake shrinkage.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"13 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142986449","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}

Regional differences and interactions among various elements enhance the complexity of addressing these issues, which not only makes resource and environmental management challenging, but also requires flexible and dynamic management strategies to cope with multilevel and multidimensional conflicts and uncertainties. Moreover, effective management of resources and environmental impacts requires the integration of numerous factors and adaptative strategies to respond to the continuously changing environmental conditions and evolving societal needs. Here, we introduce a conceptual framework and evaluation index system for resource and environmental carrying capacity (REECC) from \"production-living-ecology\" spaces(PLES) perspective. We used this framework to quantitatively evaluate REECC in the western Jilin Province and to conduct in-depth analyses of its internal drivers and climate impacts. The REECC and direction of movement of the center of gravity of different land-use types were also assessed. Spatial and temporal changes in REECC in this region over the period of 2005-2020 were particularly striking. In 2005, areas with an REECC between 0.4-0.5 accounted for 47.89% of total areas, but this fell to 37.16% in 2010 before leveling off at 41.76% in 2015–2020. Population density was the primary influencing factor, followed by EVI and PM2.5. Precipitation was significantly positively correlated with REECC, whereas temperature was significantly negatively correlated with REECC. The direction of the REECC trend was found to be consistent with that for grasslands, and the position of the center of gravity was shifted.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"7 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142986453","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}

Malachite green (MG) is one of the refractory contaminants that is frequently found in textile effluent. This study focused on examining the photocatalytic degradation of MG dye with the use of a heterogeneous hybrid citric acid modified Hydroxyapatite and Zinc oxide (CA@HAp/ZnO) photocatalyst. The CA@HAp/ZnO photocatalyst was synthesized and characterized through various analytical techniques such as FTIR, SEM, EDX, XRD, XPS, BET, TGA, PL, and UV-DRS. Optimization of parameters including solution pH, dose of the prepared photocatalyst, irradiation time, and initial dye concentration was carried out using the batch method. The enhanced photocatalytic performance is observed due to the direct Z-scheme mechanism which successfully separated electron-hole pairs, acquired within a minimum dosage of 10 mg and after 40 min at near neutral pH, reached its maximum degradation efficiency of 98.75% under visible light. Additionally, in five consecutive cycles CA@HAp/ZnO demonstrated excellent photocatalytic-stability for the degradation of MG with a negligible decrease in catalytic activity. The application of LC-MS enabled the identification of potential oxidative pathways for MG, along with the detection of reaction intermediates. This research offered a realistic arrangement and boosted photocatalytic activity for the beneficial clean-up of dyes from contaminated water without generating any secondary pollution.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"26 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142986496","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}

To address these issues, this study proposes a novel approach, the 7Q dynamic frequency method, which calculates ecological flow by integrating basic and characteristic hydrological frequencies, based on the dynamic stability criterion of flow over seven consecutive days. The hydrological data used for the calculations is derived from the natural runoff restored by the Sliding-GRU model, with the previous period treated as the natural period based on the division of hydrological periods determined through hydrological mutation analysis. Furthermore, the health status of the river is assessed by the ecological flow guarantee rate at different time scales, after evaluating the suitability of the 7Q dynamic frequency method through the construction of an evaluation system. Taking the lower reaches of the Fuhe River as the study area, the results indicate that the flow series of the river can be divided into four hydrological periods with an overall low degree of hydrological alteration. The ecological flows calculated for each hydrological period using the 7Q dynamic frequency method are both reliable and highly suitable for the river’s hydrological characteristics, ensuring the basic water conditions of the river ecosystem. Overall, the guarantee degree of ecological flow in the river is low, decreasing from the natural period to the impact period, with an upward trend during the transition period. Moreover, the long-term guarantee rate is higher than the short-term guarantee rate across all hydrological periods. This study provides valuable theoretical and methodological support for the scientific determination of ecological flow.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"14 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142988249","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 the empirical context of cheating on emissions by a major car manufacturer, survey research was conducted, and data were collected. The findings of this study reveal that moral disengagement acts as a shield that partially protects a firm’s reputation for sympathy against news about environmental transgressions.

However, further investigation is needed to optimize the balance among phosphorus recovery, heavy metal leaching, residual hydrochar utilization to enhance overall process benefits. In this study, acid leaching on hydrochar was conducted using HCl, H<sub>2</sub>SO<sub>4</sub>, citric acid at 0.1 – 1.0 M acid concentration for 10 – 1440 min, the liquid-to-solid ratio between 50 to 500 mL/g. Employing single-factor experiments, response surface methodology, various characterization techniques, the impacts of acid leaching on the leaching rates of phosphorus and heavy metals, along with residual rate and properties of the remaining hydrochar, were quantitatively assessed. The results indicate leaching parameters directly impact the phosphorus leaching rate. HCl and H<sub>2</sub>SO<sub>4</sub> achieve their corresponding maximum phosphorus leaching rate within 60 min at acid concentration 0.5 M, liquid-to-solid ratio 500 mL/g, while using citric acid requires 360 min. When H<sub>2</sub>SO<sub>4</sub> is used as the extractant, the corresponding maximum phosphorus leaching rate can be maintained within a wider leaching time and acid concentration range. A moderate acid concentration, prolonged leaching time, higher liquid-to-solid ratio lead to increased levels of heavy metal concomitant leaching. Compared to HCl and citric acid, using H<sub>2</sub>SO<sub>4</sub> as extractant results in lower heavy metal leaching and lower sensitivity to leaching parameters. The residual rates of hydrochar range from 59.3% to 77.3%, with H<sub>2</sub>SO<sub>4</sub> and HCl as extractant yielding higher residual rates than citric acid. The properties of the remaining hydrochar were altered by acid leaching, resulting in a decrease in specific surface area and pore number, but an increase in oxygen-containing functional groups and calorific value, which affects its subsequent utilization. Finally, based on the aforementioned results and potential process scenarios, the selection of optimal acid leaching parameters was discussed.

However, the efficiency of P recovery is often hindered by homogeneous crystallization. This study aims to elucidate the role of homogeneous crystallization in hydroxyapatite (HAP) formation and its influence on P recovery efficiency. We employed pH monitoring to assess the induction time for homogeneous crystallization, while simultaneously tracking changes in calcium and P concentrations during both formation and transformation stages. Our findings indicate that adjusting operational parameters significantly influences P removal efficiency and the induction time for phase transition in the crystallization process. Specifically, increasing the pH from 8 to 10 resulted in an enhancement of P removal efficiency, rising from 36 % to 99 %. However, this increase in pH corresponded with a substantial prolongation of the induction time for phase transition, extending from 0.53 h to 15.8 h. In contrast, raising the temperature from 15 °C to 35 °C improved P removal efficiency from 23.62 % to 56.80 % while concurrently decreasing the induction time for phase transition from 10.45 h to 1.31 h. The transformation to HAP occurs primarily through the dissolution-recrystallization of ACP. By carefully regulating operational parameters, we can control the formation and transformation of the homogeneous precipitate, thereby enhancing P recovery efficiency. This research provides valuable insights into the composition, formation, and transformation mechanisms of fine particles during P recovery, while also offering a novel perspective for assessing the risks associated with homogeneous precipitates.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"55 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142988250","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}
