When disturbed by loading operations and wind, these rock piles release considerable dust, leading to significant environmental pollution. This study aims to develop an environmentally friendly and cost-effective method for dust control in disturbed areas of open-pit coal mines, using Sporosarcina pasteurii as a microbial dust suppressant to explore its potential application and development. Laboratory experiments were conducted to simulate the growth characteristics of Sporosarcina pasteurii in the microenvironment of blast pile dust. The effectiveness of the microbial dust suppressant was evaluated under conditions of impact disturbance and rainfall erosion through wind and rain erosion tests. Results showed that under optimal conditions, the wind erosion resistance of treated samples improved significantly, with an increase of 98.24%, 86.99%, 64.08%, and 40.98% after 1, 2, 3, and 4 impact disturbances, respectively. Additionally, rain erosion resistance improved by 75.55% after 35 min of simulated rainfall. The growth conditions of Sporosarcina pasteurii in blast pile dust leachate were similar to those in sterile water, demonstrating robust growth and consistent urease activity of 7.78 mmol L⁻¹ min⁻¹ after 24 h. The mineralization product was calcite-type CaCO₃ with uneven particle sizes.

However, the appropriate P/E ratio for BSFL in the waste treatment process has remained unknown so far. This study utilized several common production chain residues to prepare diets with varying P/E ratios, to observe growth performance, nutritional components, fatty acid composition, fatty acid conversion, amino acid composition, waste-to-biomass conversion, and nitrogen emission levels of the BSFL. The results indicated that by adjusting the P/E ratio within the range of 9.79-17.8 mg/kJ, biomass conversion increased from 8.79% to 11.60% (an increase of 31.97%), nitrogen conversion enhanced from 27.31% to 40.99% (an increase of 50.10%), while nitrogen emissions reduced from 2.69 g to 0.48 g (a reduction of 82.16%). Compared to other reported methods, adjusting the P/E ratio proved more effective and cost-efficient. The P/E ratio 11.67 mg/kJ is relatively more suitable for using BSFL in organic waste treatment. Due to the significant variation in nitrogen levels within typical organic waste, our research findings advocate for the mixed treatment of multiple waste types to ensure the P/E ratio close to 11.67 mg/kJ.

Using a two-tier supply chain framework, the study examines the differences in cost-sharing across various types of innovation and the impact of game players on product greenness. A stochastic differential game model involving a shared supplier and two competing manufacturers is constructed. Main findings are as follows: (1) In green product innovation, when market preference for greenness is relatively low, the formation of cost-sharing contracts is less influenced by the intensity of greenness-based market competition. In such scenarios, government subsidies emerge as a crucial tool to effectively guiding the market mechanism towards achieving its intended objectives. (2) As the market competition intensifies, manufacturers' incentives towards suppliers will shift from reducing costs to increasing demand. (3) When the intensity of green competitive is low, and supplier process innovation efficiency is high, manufacturers should bear a greater share of costs; Conversely, suppliers should bear more costs. When supplier process innovation efficiency is higher and market competition is stronger, suppliers should bear more costs if consumer green preferences are lower. (4) Over time, considering consumer preferences, a marginal increase in price exceeds the marginal increment in greenness with respect to contributing to stabilise price fluctuations. Conversely, it tends to raise the mean value of the price. (5) The increase in market competition intensity accelerates suppliers' and manufactures' strategy adjustments for green product innovation, but decelerates the strategy adjustment for suppliers' green process innovation.</p>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"373 ","pages":"123545"},"PeriodicalIF":8.0,"publicationDate":"2024-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142826992","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}

This paper constructs a quasi-natural experiment based on the issuance of green municipal bonds, and empirically examines its carbon emission reduction effects by using the staggered difference in differences approach. The issuance of green municipal bonds can substantially diminish the level of carbon intensity and pass a series of robustness tests. Green municipal bonds can generate green project financing effect, greening effect and industrial structure allocation effect to promote the reduction of carbon emission level in a region. At the same time, there exists heterogeneity in local governments' emphases on environmental protection, economic development, carbon peaking progress and urban resource endowment. Further research found that green municipal bonds have significant spatial spillover effect, which not only promotes the reduction of local carbon intensity, but also leads to the reduction of carbon intensity in the surrounding cities. The proposed policy implications include: increase the proportion of green municipal bonds in local government bonds; establish standardized issuing criteria of green municipal bonds, accelerate credit rating and improve performance management of green municipal bonds; design green municipal bonds according to local conditions; and strengthen green finance and its supporting services.</p>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"373 ","pages":"123692"},"PeriodicalIF":8.0,"publicationDate":"2024-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142826905","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}

These impacts include hydrological instability, which can cause severe damage, especially where infrastructures are present. Post-rehabilitation measures can be useful in reducing or preventing erosion or hydrogeological risks. Decision-makers are called on to prioritize post-fire intervention areas and allocate public funds for this purpose. This work focuses on the assessment of erosion and hydrological risk potential in forested slope areas affected by wildfire using a Multi-Criteria Decision Analysis (MCDA) approach integrated with a GIS environment on a regional scale. Expert perception was considered using the pairwise comparison method as part of the Analytical Hierarchy Process (AHP). This allows expert stakeholders to rank relevant criteria, providing a quantitative metric (weight) for qualitative data. Two MCDA methods are used and compared: Weighted Linear Combination (WLC) and Ordered Weighted Averaging (OWA). Fire frequency, slope (gradient and length), and proximity to infrastructures were found to be the most important factors by the stakeholders. The WLC method provides evidence classified into high and moderate suitability class areas characterized by high values for fire frequency or slope gradient. Conversely, the OWA method, ranging from low to high risks, makes it possible to adapt the method and obtain a range of suitability maps. Novelties of the MCDA-GIS combined methodology adopted in this work are its application on a regional scale and the combination of vulnerability and driving-force factors (namely presence of grey infrastructures, fire frequency). The MCDA-GIS methodology can be suitable for public administrations in that it allows for mapping a regional area more quickly and thus facilitates sector planning.</p>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"373 ","pages":"123672"},"PeriodicalIF":8.0,"publicationDate":"2024-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142826921","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}

This study examined the impact and efficacy of biomethanization processes on the biodegradation of Equisetum alkaloids. To monitor the biodegradation in such complex matrices, a sample preparation method and a high-performance liquid chromatography electrospray ionization mass spectrometry (HPLC-ESI-MS/MS) method were established. The developed method was successfully employed to quantify the total residual content of Equisetum alkaloids in fermentation residues following biomethanization in batch experiments. It was demonstrated that under such conditions a degradation greater than 95 % was achieved. The biomethanization process described here is currently the most effective biological treatment for reducing Equisetum alkaloids.

These programs always operate under some degree of uncertainty, and adaptive management is often used as an iterative learning process to assist decision making under uncertainty. Monitoring plays a critical role in adaptive management as knowledge is gathered to evaluate the effectiveness of the interventions to resolve uncertainty and improve decisions. While there is extensive literature on improving adaptive management, little has focused specifically on monitoring. In this paper, we examine the role that different types of monitoring play in supporting adaptive management and how monitoring programs are conceived and evolve over time. We propose a novel double-loop framework that facilitates identification of critical uncertainties and iterative adjustment of the investment in monitoring to support management. It foreshadows a shift in monitoring resources away from filling knowledge gaps as understanding of ecosystem processes improves, towards other knowledge gaps or fundamental environmental outcomes. We demonstrate the framework through a case study on golden perch responses to environmental flows in the Goulburn River, Australia. After 8 years of monitoring, an initial knowledge gap regarding the flow-spawning relationship for golden perch has been filled, and we recommend now reducing monitoring effort in this area to redirect resources to other critical uncertainties. This framework is broadly applicable across various fields. It has the potential to enhance the efficiency and effectiveness of environmental management programs and strengthen purposeful learning within the adaptive management cycle.</p>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"373 ","pages":"123694"},"PeriodicalIF":8.0,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142823667","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}

This study utilizes the pilot implementation of the ECES as a quasi-natural experiment, integrating data from Chinese industrial firms and pollution statistics from 2003 to 2014. Employing a difference-in-differences approach with multiple time points, we conduct an empirical assessment of the ECES's impact on pollution reduction. The results indicate that the ECES effectively curtails corporate pollution emissions. Heterogeneity analysis reveals that the pollution reduction effects are more pronounced in state-owned firms, large-scale firms, and in regions with stringent environmental regulations and high public environmental awareness. Mechanism testing demonstrates that the ECES mitigates pollution emissions primarily by alleviating financing constraints and promoting positive environmental behaviors. In terms of proactive pollution prevention and end-of-pipe treatment, the latter is more significantly influenced by the incentives provided by the ECES. Further analysis indicates that specific features of the ECES, such as mandatory participation and the establishment of credit ratings, are particularly conducive to enhancing its pollution reduction efficacy.

In practice, small and medium-sized manufacturers have insufficient cash to balance equipment upgrades and daily production. Under a two-stage setting, this study examines a pull supply chain consisting of a capital-constrained manufacturer and a retailer, where the manufacturer can borrow bank loans. In the investment stage, the manufacturer chooses among the non-upgrading mode, purchasing mode, and leasing mode. In the following production stage, the manufacturer produces to satisfy the uncertain demand through a retailer. The results show that the preference of the three modes depends on the cost reduction coefficient, residual value of upgraded equipment, and revenue of moral hazard events. Due to increased liquidity risk, the manufacturer upgrades equipment by purchasing only when the residual value of upgraded equipment is relatively large. However, the manufacturer upgrades equipment by leasing even when the moral hazard events induce a penalty since leasing eliminates the liquidity risk over the investment stage. Simultaneously, there exists a cost reduction trap where the production's marginal profit is seized by the reduced wholesale price, and the manufacturer upgrades equipment only when the cost reduction coefficient is medium. For the environment, equipment upgrades do not always benefit the environment. If the cost reduction coefficient is relatively large, the increased production quantity offsets the unit emission reduction, leading to larger total emissions. To ensure a \"win-win\" situation for the manufacturer and environment, the leasing mode should be adopted when the turn-over times and transportation impact of returning equipment are controlled, since the agent friction effect is weaker.
