This study examines microplastic (MPS) presence and distribution in Bosten Lake and their interaction with microorganisms. We employed a Confocal Raman spectrometer to identify MPS types and 16S rRNA high-throughput sequencing to analyze microbial diversity and composition. In May, the lake's average microplastic concentration was 108.20 particles per liter (PCS/L), decreasing to 21.67 PCS/L by October. Transparent and yellow fibrous microplastics, predominantly 0.2–0.5 mm in size, were most common. Key microplastics in May included PEEK (27%), PMMA (25%), and PET (9%), while October saw a prevalence of PET (35%), PS (13%), and PA (9%). Higher microplastic concentrations correlated with reduced microbial diversity. In May, the high microplastic concentration group (MH) showed increased <em>Planctomycetota</em>, while in October, <em>Patescibacteria</em> and <em>Bacteroidota</em> rose significantly in the high plastic group (OH), known for microplastic degradation. MH also had a higher abundance of <em>Cryptomycota</em> compared to OH. Functional analysis indicated that MH had more genes related to bisphenol, benzene, and chlorine compounds, whereas OH had genes linked to methane, nitrogen, and organic matter degradation. Microplastic concentrations peaked near the lake inlet and tourist areas, affecting microbial quantity, diversity, structure, and function. This research enhances our understanding of MPS distribution and environmental microbial shifts in similar settings, providing essential data for environmental management strategies at Bosten Lake.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"481 ","pages":"Article 144157"},"PeriodicalIF":9.7,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142594449","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}

However, concerns have arisen regarding the lower durability of cold-mix asphalt when exposed to various environmental stressors, leading to the formation of cracks. This paper explores the benefits of a hybrid application of coarse and powdered slag to enhance crack healing in cold-mix asphalt through the use of microwave radiation. To do so, we quantified extent of microwave-induced healing in dry, wet and freeze-thaw conditioned cold mix asphalt containing steel slags. Latter healing is facilitated by heat generated via absorption of electromagnetic waves. Heat distribution within the specimens and crack zone found to be more uniform when the coarse slag (>4.75 mm) was supplemented with slag powder (∼0.075 mm) as evidenced by thermography analysis. It was further found that freeze-thaw conditioned specimens significantly benefited from microwave-induced healing as evidenced by a 74% recovery in semi-circular bending strength. This enhancement is attributed to the increased diffusion and contact area at heated crack surfaces. Overall, microwave treatment of cold mix asphalt specimens showed an increase in binder wettability and aggregate coating, resulting in improved performance. Notably, the most significant improvements were observed in the stiffness modulus, with increases of 23%, 46%, and 70% for dry, wet, and freeze-thaw conditioned specimens, respectively. Study outcomes support the vision toward the NetZero carbon emission pavements by promoting the durability of cold-mix asphalt to be a viable alternative to hot-mix asphalt.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"482 ","pages":"Article 144170"},"PeriodicalIF":9.7,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142594384","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}

Two types of rubber, natural rubber (NR) and butyl rubber (BR), were employed as matrices, and eight composites were fabricated by increasing SG loadings [0, 10, 20, and 30 parts per hundred rubber (phr)]. The effects of these SG loadings on the composites' morphological, physical, thermal, wettability, mechanical, dynamic mechanical, vibration-damping, and acoustic properties were thoroughly investigated. The findings demonstrate significant improvements with increasing SG loading, particularly in the BR/SG30 composite. By reinforcing 30 phr of SG into the BR matrix, the density, hardness, thermal degradation, and sound-insulating properties improved by approximately 3.50%, 15.64%, 6.05%, and 5%, respectively, compared to the NR/SG0 composite. The damping ratio (ξ) of MSBB + BR/SG30 was approximately 18.04 at the second vibration mode, and the overall sound power level of MSBB was reduced by about 12.20 dB(A) when the BR/SG30 composite layer was applied, highlighting its potential for real-world vibration and noise control applications. These results underscore the significant role of SG as a sustainable reinforcing filler in enhancing the properties of rubber composites, particularly in the BR matrix, making it a promising option for applications requiring effective vibration and noise control.

Although some reviews exist on ML in water resources, a systematic assessment of water quality in water distribution systems is lacking. The current review offers the first critical and comprehensive review of the application of ML in water quality management within water distribution systems, including water quality prediction, anomaly detection, and contamination source identification, and addresses the associated challenges and future directions. To be specific, for water quality prediction, the focus is on chlorine, disinfection by-products, microbial indicators, heavy metals, and sensory properties. The implementation of ML has the potential to reduce the cost of water quality monitoring and offer knowledge discovery. For anomaly detection, semi-supervised, supervised, and unsupervised models are reviewed. Changes in one or more surrogate water quality parameters measured by low-cost sensors can effectively indicate anomalous events. For contamination source identification, ML demonstrates its superiority in rapidly and accurately locating contamination sources. Additionally, dataset availability, interpretability, generalization capability, integrated models, real-time response and proactive decision have been identified as key areas for implementing ML.

The study uses China's “province-managing-county” reform (PMCR) as the starting point. Our results reveal that (Abbasi and Ahmadi Choukolaei, 2023) the PMCR has significantly promoted energy transitions through three mechanisms: increasing county-level governments' fiscal self-sufficiency and resource integration capabilities, enhancing the industrial structure and fostering green technological innovation, and increasing rural residents' income (Aziz and Bakoben, 2024). These effects are enhanced with increased agricultural mechanization, economic vitality, and provincial government attention to energy (Callaway and Sant’Anna, 2021). The PMCR contributes to reducing energy consumption disparities among counties and reducing carbon emissions (Chen et al., 2022). Clarifying county-level government expenditure responsibilities in the reform would further aid the energy transition. To promote green development, countries with decentralized systems should promote reforms for the rational distribution of revenue and expenditure responsibilities and capacity for the fiscal security of sub-provincial governments in central–local relations.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"481 ","pages":"Article 144156"},"PeriodicalIF":9.7,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142580374","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}
