Physicochemical characterization revealed that CBBC possesses a mesoporous structure with a BET surface area of 78.9 m²/g and abundant oxygen-containing functional groups that provide active sites for metal binding. Batch experiments analyzed using the Langmuir model (<i>R</i>² = 0.99) confirmed the monolayer adsorption capability of CBBC. The effects of flow rate, starting lead concentration, and bed height on adsorption performance were evaluated in fixed-bed column experiments. The findings indicated that at an influent concentration of 100 mg/L, the maximum adsorption capacity was 151.35 mg/g, highlighting the effectiveness of CBBC. The adsorption mechanism was analyzed using the Thomas, Adams-Bohart, and Yoon-Nelson models, which agreed with the findings of earlier studies. CBBC effectively removes Pb(II) from water, making it a promising material for practical water treatment applications.

It is, however, sensitive to many different factors including operating conditions, the dynamics of electrodes and the characteristics of the wastewater being treated. In addition, these factors are correlated; therefore, there is an increasing need for the development of AI-based tools that can model non-linear (NL) systems and provide a more accurate optimization process. In real life applications, sensitivity has been reported not only in the efficiency of EC treatment, but also in the energy required per unit of wastewater treated, as well as difficulties when scaling up EC systems from laboratory to industrial applications. This comprehensive study of the basic principles; key process parameters; and the key processes of reactors, electrodes; etc., and their limitations will provide an overview of how various types of artificial intelligence (AI) algorithms, including artificial neural networks (ANNs), adaptive neuro fuzzy inference systems (ANFISs), support vector machines (SVMs), and combinations thereof, can provide the necessary tools to predict, analyze and optimize the results of electrochemical processes. An assessment of how some of the main operational variables that can impact EC performance (e.g., pH, current density, electrode type and configuration, and length of treatment time) impacts the efficiency of pollutant removal, energy use, and electrode life, will also be included. These methods of analysis are able to accommodate complexity, multivariate nature and NL relationships of all the operational variables that have an impact on EC performance. Rather than a simple review of methods, this paper provides a holistic perspective that connects the mechanisms of electrochemical processes with current modelling trends being used to predict performance based on the use of data-centric methods in conjunction with physicochemical theories.</p>\u0000 </div>","PeriodicalId":35327,"journal":{"name":"Environmental Quality Management","volume":"35 4","pages":""},"PeriodicalIF":1.3,"publicationDate":"2026-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147615323","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}

This multidisciplinary review critically examines conventional, advanced, and emerging technologies for the separation and treatment of O&amp;G-laden wastewater. It explores the environmental implications and health risks associated with O&amp;G-contamination, including aquatic toxicosis, bioaccumulation, and infrastructure degradation. Uses of traditional approaches are acceptable due to their simplicity and cost-effectiveness; but for emulsified and dissolved fractions require an integration of advanced techniques. Membrane filtration (UF, NF, RO), electrocoagulation, adsorption using novel materials, advanced oxidation processes (AOPs), and magnetic separation offer enhanced removal performance and adaptability. Applications of biological methods like microbial degradation, enzymatic treatment, constructed wetlands, etc., represent eco-friendly alternatives. This review emphasizes hybrid and integrated systems such as membrane bioreactors (MBRs), physico-biological combinations, and electrochemical-adsorptive setups, which leverage synergistic mechanisms to improve removal efficiency and operational robustness. Here, some key designs are considered, such as pH, temperature, O&amp;G concentration, sludge management, energy demands, etc. It emphasizes the potentiality of O&amp;G recovery and reuse, notably in biodiesel production and energy recovery. Surfactants and natural organic matter mainly stabilized oil and water emulsion, reduce droplet coalescence, and intensify membrane fouling and coagulant demand, and difficult to operate. Elevated salinity and divalent cations modify interfacial charge, and alter electrocoagulation efficiency, adsorption equilibria, and microbial activity. High suspended solids and colloidal loads further exacerbate pore blocking, sludge production, and hydraulic instability, thereby limiting flux, increasing energy consumption, and complicating scale-up. Despite significant progress, it faces some challenges. Future research may establish predictive design models and standardized performance benchmarks. Present review is strongly connected to current research gaps and future directions towards low carbon &amp; energy and resource-recovery-oriented treatment systems to address monitoring of O&amp;G pollution in wastewater.</p>\u0000 </div>","PeriodicalId":35327,"journal":{"name":"Environmental Quality Management","volume":"35 4","pages":""},"PeriodicalIF":1.3,"publicationDate":"2026-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147615301","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}

Due to their small size, microplastics can be ingested and accumulate in body tissues of organisms. This raises concerns about their toxicity being transferred to humans via food consumption. However, there are still a limited number of studies on microplastic pollution, especially conducted in Miri, Sarawak, Malaysia. This study aims to determine the abundance and characteristics of microplastics in commercial marine fish in city of Miri, Sarawak, Malaysia. Microplastic ingestion was observed in the gastrointestinal tract of 22 individuals from three commercial marine fish species collected from three different local Miri fish markets. Five grams of dissected gastrointestinal tract was extracted with alkali digestion, followed by density separation and filtration. Then, the sample was identified by multi-detection techniques such as stereomicroscope for quantification, and morphological analysis along with ATR-FTIR for chemical characterization. The abundance of ingested microplastics was within the range of 47.03–367.24 items/kg. The highest microplastics concentration was observed in Indian mackerel, implying the potential indicator species. The identified particles had fiber morphology, predominantly polyester (PET) with fiber (73%), black color (48%), and a size range of &lt;1 mm (59%). The observed polymer compositions observed were polystyrene (PS), PET fibers, silicon polymer, and polyamide (PA). Overall, this study established a pathway for utilizing marine fish as a biological indicator in monitoring marine pollution in Miri, Sarawak, Malaysia.

The present study analyses the occurrence, characteristics and human-health risk potential of MPs in Indian tap water (TW) and bottled water (BW) using bibliometry-based systematic review, compiled from various primary literatures published earlier and associated health-risk assessment. Concentrations of MPs in BW ranged from 0.67 to 10,000 MPs/L, with noncommercially bottled brands containing an average of 212 ± 100 MPs/L and commercially recognized brands contained between 0.67 ± 0.58 and 4.67 ± 3.06 MPs/L. In contrast, TW samples showed lower MP concentrations that varied from 4.3 to60MPs/L. Morphological analysis showed that the most frequent types found were those that were fiber and fragment in shape and dark blue, black, and transparent. Polyethylene (PE), polyethylene terephthalate (PET), and polypropylene (PP) were the most frequently observed polymer types, mainly found in plastic containers, bottle caps, packaging materials, and industrial wastes.

In addition to waste management efforts undertaken by authorities, individual-level commitment to reduce plastic consumption should be highlighted as part of consumer-level interventions. Societal factors, such as subjective norms, facilitate individual factors in motivating prosocial behaviors. The current study is examining the relationship between knowledge, attitude, and practice (KAP) toward single-use plastics (SUPs) and intention to stop using them, as well as the role of subjective norm as a mediator in the relationships. This study recruited 509 consumers in Malaysia to complete an online questionnaire. Cross-sectional design was used for the study. Based on structural-equation modeling analysis, attitude is the strongest predictor for intention to quit SUPs in comparison to knowledge and practice. However, all three factors in KAP are significantly related to intention to quit SUPs, with a positive association with knowledge and attitude, whereas a negative link with practice. Subjective norms strengthen the relationship between attitude and intention, but not knowledge and practice. This study suggests that consumer-level interventions should focus on increasing positive attitudes toward quitting SUP in conjunction with creating a subjective norm that promotes it from a societal level. Encouraging individuals to adopt sustainable habits helps create a ripple effect, where social influence and shared responsibility drive long-term behavioral change and policy compliance.
