In this context, the use of a UV-LED strip light surface modified with TiO₂/graphite as a flexible photoanode has shown promise as an efficient tool for wastewater treatment. In this study, a systematic investigation of the operating variables affecting the performance of the flexible photoanode was conducted, aiming to maximize the photo-electrocatalytic production of hydroxyl radicals (^•OH). A 2³ factorial design was employed to evaluate the individual and combined effects of cell potential, electrolysis time, and light intensity on photo-electrocatalytic coumarin removal, monitored by UV–Vis spectroscopy. The concentration of ^•OH was determined indirectly through its reaction with coumarin, measured using fluorescence spectroscopy. Given the high oxidative potential and non-specific reactivity of ^•OH towards organic molecules, the optimal operational conditions were subsequently applied to assess the system’s capacity to degrade sulfamethoxazole, a representative emerging contaminant, determined by high-performance liquid chromatography. The results indicate that adaptable and scalable photo-electrocatalytic devices employing internally illuminated LED-based photo-active electrodes enhance semiconductor activation, offering an effective approach for the treatment of organic pollutants in water.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":"236 12","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144853642","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}

While the fine characterization of DNAPLs migration process in porous media is crucial for remediating the contaminated sites. In order to finely characterize the migration process of DNAPLs in porous media, trichloroethylene (TCE) was selected as a typical DNAPLs pollutant in this paper. Then, based on the laboratory sand box model, image method and electrical resistivity tomography (ERT) technology were used to monitor the migration process of DNAPLs in saturated heterogeneous and homogeneous porous media, and the migration rules of TCE in different porous media were discussed and verified to achieve fine characterization of pollutant. The results of the sand box experiment indicated that when the particle size of heterogeneous quartz sand was small, TCE mainly migrated horizontally, and with the increase of quartz sand particle size, the vertical migration gradually dominated. For the homogeneous quartz sand media, TCE was also mainly horizontally migrated, supplemented by vertical migration. With the increase of pollutant injection time, TCE was mainly vertically migrated. When approaching the bottom of the sand box, the vertical migration speed of TCE in both heterogeneous and homogeneous quartz sand media slowed down, and the DNAPLs contamination pool could be formed at the bottom of the sand box. Generally, this paper uses the image method to visually reflect the migration of DNAPLs, and indirectly characterizes the distribution characteristics of DNAPLs by ERT technology, which is of great significance for studying the migration rule of DNAPLs and determining the pollution scope and degree, and can provide certain guiding value for fine characterization and low-cost remediation of DNAPLs pollutants in actual contaminated sites.</p></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":"236 12","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144853644","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 one-step method combined both chemical and thermal activation in a single process which reduced the complexity involved with the traditional approach where initial carbonisation step is followed by chemical activation before another carbonisation. Adsorption process parameters, such as phenol concentration (50–250 ppm), adsorbent dosage (50–250 mg), contact time (5–50 min), and pH (2–12) were optimized for both activated chars using Box Behnken design (BBD) response surface methodology design. The BBD statistical tool showed that the quadratic model describing the adsorption efficiency was significant with an R² ≥ 0.98. The maximum adsorption efficiency and capacity were 95% and 360 mg/g for KAC-1 and 99% and 467 mg/g for KAC-2 activated char. The SEM image showed a porous morphology with a BET-specific surface area of 956 m²/g for KAC-1 and 1404 m²/g for KAC-2. Quantum chemical DFT analysis revealed that KAC-2 lowered the HOMO–LUMO energy gap (ΔE) for the KAC-2 phenol complex and enhances the adsorption capacity with a relative free energy of 60.05 kJ/mol. The regeneration study showed that both KAC-1 and KAC-2 can be used up to five cycles maintaining a removal efficiency of &gt; 85%. Hydrogen bonding and π-π interaction between phenol and adsorbent surface were the main adsorption mechanisms identified. The adsorption isotherms for KAC-1 followed Langmuir (monolayer) while it was Freundlich (multilayer) for KAC-2.

The NIOSH Method 600 was used for PM₄ sampling, while NIOSH Method 800 was employed for bioaerosol sampling in these environments. Pulmonary Function Tests (PFT) were administered to 23 podiatrists and 19 office workers.

PFT analysis revealed notable differences between podiatrists and office workers with similar smoking habits. A negative correlation was identified between PFT results and bacterial and PM₄ concentrations in the workplace environment, indicating that as PM₄ and bacterial concentrations increased, certain PFT spirometry tests decreased (DLCO, FEF_25-75, FEV₁, FVC). Taken together, these findings suggest that the presence of bioaerosols and PM₄ in the workplace may impact employee health.
