Current literature indicates a gap in optimizing carbon modification techniques to enhance FCDI efficiency. The research systematically investigates an optimal alkali-to-carbon ratio of 2:1, which significantly enhances the specific surface area and pore structure of activated carbon, correlating with improved adsorption capacities and lower effluent fluoride concentrations. Durability tests across multiple operational cycles show consistent fluoride removal efficiency and minimal conductivity variations in the effluent. Additionally, the effects of operational parameters such as voltage and hydraulic retention time (HRT) are explored, demonstrating that extended contact times and optimized electrical settings further enhance system performance. The findings indicate that the modified FCDI system offers significant potential for sustainable, large-scale applications in municipal and industrial wastewater treatment, combining high efficiency with robust performance.

Addressing this issue is crucial, and bioremediation stands out as a sustainable solution for remediating contaminated soils. This study evaluates the feasibility of bioremediation to mitigate soil contamination by petroleum hydrocarbons using laying hen manure as a biostimulating agent, in the forms of manure stabilized by simple drying and compost from fresh manure. The specific objectives included analyzing the interaction between manure and contaminants, evaluating the influence of physicochemical and microbiological variables, comparing the efficiency of different manure proportions, and assessing contaminant reduction rates. Physicochemical and biological monitoring and statistical analysis were conducted. The results indicate that the treatment with stabilized manure significantly differed from the control sample, achieving up to 98% reduction in total petroleum hydrocarbons concentrations within 60 days and microorganism populations of around 10⁷ CFU/mL. In contrast, the treatment with compost did not show significant differences from the control. Furthermore, while both treatments increased microbial populations, only the compost treatments maintained non-toxic conditions for soybean seed germination and root elongation, highlighting its potential for agricultural applications post-remediation. Stabilized poultry manure, though effective in total petroleum hydrocarbons degradation, resulted in soil toxicity due to high salinity and potassium levels, necessitating careful management. Its combined application with sawdust is recommended to improve soil structure and counteract compaction. These findings underscore the effectiveness of stabilized manure in accelerating bioremediation and the potential of compost to enhance soil health, suggesting tailored applications depending on specific remediation goals.</p></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":"235 8","pages":""},"PeriodicalIF":3.8,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141719108","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}

A reed length was divided into three equal parts at three consecutive stations, ST1, ST2, and ST3. Natural reeds had a dimension of 3.5 km long, 1.2 km wide, and 0.5 m deep between two consecutive stations. According to the study, natural reeds were effective in removing agricultural herbicides and improving agricultural drainage water quality. ST3, which was the furthest from the entry point, had the largest difference in agricultural herbicides concentrations compared to their initial concentrations, as well as the highest removal efficiency (100%) during all four retention times (1.26, 1.10, 1.30, and 1.60 days). Natural reed at this distance from the entry point significantly reduced TC and FC. The ST3 station had the highest removal efficiency of TC and FC, with average values of 62 and 83%, respectively, while ST1 had the lowest (with values of 9 and 34%). Due to the differences in performance between ST1, ST2 and ST3 stations, ST2 is considered the most efficient and cost-effective station. The Khuzestan province has a water shortage and agricultural drainage water problems. Treating drainage water with environmentally friendly methods, like natural reeds, will prevent contamination of water sources and result in a significant amount of water entering the system.</p></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":"235 8","pages":""},"PeriodicalIF":3.8,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141719109","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}

Due to the strong spatial and temporal correlation of air quality changes, existing air quality prediction methods often face the problem of low prediction accuracy due to insufficient extraction of spatio-temporal features. In this paper, we proposed a self-tuning spatio-temporal neural network (ST2NN) to enhance air quality prediction. ST2NN model consisted of four modules. First, ST2NN model constructed a temporal feature extraction module and a spatial feature extraction module based on gated recurrent unit (GRU) and graph convolutional neural network (GCN), respectively, and the two feature extraction modules adopted a parallel structure, which could effectively extract the spatio-temporal features in data. Additionally, ST2NN model constructed a feature fusion module based on gating mechanism to delineate the contribution of spatio-temporal features to the predicted values. Further, ST2NN model constructed a Hyperband hyperparameter optimization module based on Hyperband optimization algorithm to automatically adjust the network hyperparameters. The structure of ST2NN model endowed it with excellent spatio-temporal feature extraction and parameter adaptability. ST2NN model was evaluated and compared with existing models, including convolutional long short-term memory neural network (ConvLSTM), GRU, combined convolutional neural network and long short-term memory neural network (CNN-LSTM), and GCN-LSTM for air quality index (AQI) prediction using data from twelve monitoring stations in Beijing, China. Across all four evaluation indexes, ST2NN model outperformed the comparative models, improving prediction accuracy by 0.51%-10.18% (measured using <span>({R}^{2})</span>). From the experimental results, it can be seen that ST2NN model constructed from the perspective of spatio-temporal feature extraction has better prediction performance compared with the existing air quality prediction model, which provides a new method for air quality prediction and has certain application value.</p></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":"235 8","pages":""},"PeriodicalIF":3.8,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11270-024-07346-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141719101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Here, a systematized review was conducted to explore patterns and biases in studies examining the impacts of ash on freshwater fish. Out of the 43 studies included in this review, 38 reported harmful effects of ash exposure on fish traits. The median lowest concentration of ashes capable of inducing negative effects on fish traits was found to be 2 g/L.

In contrast, biomarkers related to reproduction (94.7%) and metabolism (66.4%) had the highest proportion of non-significant associations between fish traits and ash exposure. Statistical models indicate that the ash source does not determine the direction (positive or negative) of its effect on fish traits. Furthermore, no evidence supports the hypothesis of similar sensitivity levels to ash exposure among phylogenetically closely related fish species.

Dyes were extracted from plants, animals, and minerals until synthetic dyes came to the market, as synthetic dyes were more stable, readily available, and inexpensive. Despite being extremely important to the economy, they have been among the most significant global polluters. Textile dye industries have become the chief source of water pollution, with their effluents increasing the turbidity of water and reducing photosynthesis and dissolved oxygen levels. This leads to significant damage to aquatic biodiversity, threatening the survival of many species. Synthetic dyes have carcinogenic, mutagenic, and genotoxic effects on animals and human beings, posing a severe health risk. The degradation of dyes is essential for ensuring the sustainability of the environment for future generations. The traditional physicochemical means of dye treatment are not convenient because of the high solubility in water, cost of method utilisation and other disadvantages related to these techniques. To overcome the disadvantages of physicochemical treatment, biological methods or bioremediation can be used as an alternative. The objective of this review article is to study the mechanisms involved in the degradation of textile dyes by bacteria to obtain sustainable, economically and ecologically sound solutions for dye treatment. This paper will explain the various types of natural and synthetic dyes utilised in the textile industry, their chemistry, and how they affect water and soil ecosystems. The treatment of textile dye by various physicochemical methods and their advantages and disadvantages are also discussed. In bioremediation, the microorganisms utilize organic pollutants as a source of food or energy. Bioremediation uses biosorption and enzymatic activity for dye degradation, which does not disturb natural processes and is thus sustainable. The microorganisms secrete crucial extracellular and intracellular enzymes that carry out decolourisation and degradation through a series of events, which include hydrolysis, acidogenesis, and methanogenesis. We will discuss how aerobic and anaerobic microorganisms degrade these textile dyes through the process of biodegradation and bioaugmentation and how this technology provides a clean and eco-friendly method for removing textile dyes.</p></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":"235 8","pages":""},"PeriodicalIF":3.8,"publicationDate":"2024-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141585744","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}
