The fabricated nanocomposite membranes were investigated using Fourier Transform Infrared (FTIR), thermal gravimetric analysis (TGA), X-ray diffraction (XRD) and scanning electron microscope (SEM). The membrane hydrophilicity was estimated using contact angle measurements, which revealed that the 4% loaded nanochitosan had the highest hydrophilicity. Additionally, the water uptake, porosity, water contact angle and water flux of the nanocomposite membranes were assessed. The membrane filtration performances were explored for the removal of CR and CV as anionic and cationic dyes, respectively, at different concentrations and various applied pressures (1 bar to 4 bar). The experimental data revealed a high rejection (<i>R</i>) performance for CR (<i>R</i>≃100%) with a high water flux of about 150 L/(m²·h) to 183 L/(m²·h) for the optimized membrane with 2% nanochitosan at an applied pressure of 4 bar. The rejection for CV showed a variant rejection (70%–99%) at different dye concentrations with fluxes ranging from 93.6 L/(m²·h) to 149.5 L/(m²·h) for the same composite membrane. The composite membrane showed enhanced flux recovery after fouling by bovine serum albumin and was resistant to widespread gram-positive (<i>Staphylococcus aureus</i>) bacteria.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>","PeriodicalId":807,"journal":{"name":"Waste Disposal & Sustainable Energy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142268496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Persulfate technology has a good treatment effect in reducing soil organic pollutants. Analyzing the feasibility and prospects of the applications of persulfate technology in soil organic pollution is conducive to the development of soil remediation. The activation method of persulfate treatment of soil organic pollutants is as follows: thermal activation, microwave activation, ultrasound activation, alkali activation, material activation, electroactivation and photoactivation. The influencing factors of persulfate treatment of soil organic pollutants are as follows: coexisting substance effects, persulfate initial concentrations, treatment time, soil temperature, soil pH value and soil moisture content. Persulfate technology can effectively deal with the problem of organic pollution in soil, which can be developed in the following aspects: (i) Coupling different persulfate activation technologies; (ii) Applicating activated persulfate with non-metallic activated materials in soil remediation; (iii) Coupling different soil remediation technologies with persulfate; (iv) Preparating persulfate sustained-release materials for soil remediation.

These tiny particles are derived from a wide array of human activities, including industrial processes, urban centers, and even our daily routines. To devise effective mitigation measures, it is essential to comprehend the sources and the complexity of their distribution across terrestrial, aquatic, and atmospheric domains, which adversely affect ecosystems worldwide. Extraction methods have been cultivated and established to remove MPs from the environment with higher efficiency. This paper elucidates the complexity of their dispersal and sheds light on the extraction methods along with their degradational strategies. It also discusses the use of machine learning models in MP identification, detection, and classification. The integration of machine learning, particularly with features extracted from holographic images and spectroscopic data offers a precise and efficient method for identifying MPs. The toxicological effects of MPs on organisms and ecosystems are also discussed, emphasizing the need for further research to mitigate their impact. The exploration of degradation strategies offers a promising solution to combat the pervasive presence of MPs. While several mechanisms contribute to MP degradation, microbial-driven processes have emerged as a dominant factor. This review delves deep into the realm of microbial degradation, highlighting its potential to transform the fate of these pollutants. The paper showcases the latest research and innovations, paving the way for an environmentally sustainable future. This comprehensive review emphasizes the urgency of addressing the MP predicament and presents a refined roadmap towards a sustainable future.</p><h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>\u0000","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":null,"pages":null},"PeriodicalIF":2.52,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142266799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

The treatment involved using sand filters combined with lime and eucalyptus sawdust. Key physicochemical parameters, including pH, electrical conductivity (EC), biological oxygen demand (BOD₅), mineral matter (MM), organic matter (OM), and total organic carbon (TOC), were analyzed for both untreated OMW and the filtrates produced by the treatment. The results showed that the use of lime, alone or with eucalyptus sawdust, in the filtration process significantly increased the pH and EC, while leading to a highly significant reduction in BOD₅, MM, OM, and TOC. Germination tests indicated that the highest germination rates, 80% for both wheat and barley, were achieved with specific treatment filtrates.

Our results showed that substrates with lower concentration of tailings had an increase in organic matter content and higher acidity. In contrast, substrates with higher tailings concentration showed increased levels of toxic metals; yet these metals seemed not to be readily available to plants, as evidenced by the enhanced biomass accumulation and improved seedling quality in these subtracts. Conversely, the reference soil, being nutritionally deficient and acidic, may have led to increased absorption of toxic metals by the plants. This resulted in reduced growth and increased activity of antioxidant enzymes and synthesis of flavonoids.

This review examines existing research on carbon mitigation through AUPMOW to guide future decisions on its implementation. It explores the mechanisms of carbon flow in agriculture and the characteristics of processed municipal organic waste (PMOW). Additionally, environmental, managerial, and systemic factors affecting AUPMOW efficacy are analyzed. Furthermore, it discusses the impact of policies and regulations on AUPMOW implementation. Some recommendations are made for optimizing current AUPMOW practices, including strengthening regulatory frameworks, managing soil contamination risks, reducing CH₄ and N₂O emissions during storage, considering long-term environmental impacts, selecting suitable locations, and employing minimally invasive farming methods. This review demonstrates how PMOW can improve soil carbon sequestration and offers a sustainable agricultural solution. It provides an overview of current research on the carbon mitigation potential of AUPMOW, recommends best management practices (BMPs) for future implementations, and identifies key insights for policymakers, emphasizing reduced reliance on chemical fertilizers and highlighting areas for future research.</p><h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>\u0000","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":null,"pages":null},"PeriodicalIF":2.52,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142266805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}
