The treatment by cryoconcentration consists of four steps: cooling, freezing, sweating, and melting. The operation purifies the ice in depth by partially melting the impure zones trapped in the pockets of concentrated solutions formed in the ice. Cryoconcentration yields five types of fractions liquid solutions with different concentrations of organic and mineral matter: two highly concentrated solutions compared to the raw OMW, a solution with a similar concentration to the initial one, and two purified solutions with significantly lower concentrations than the initial solution. In three cycles, the technique increased the concentration of total phenols from 22.9 to 103.2 g L^-1. The cryoconcentrated solutions have been applied to tanning hides in static mode without stirring and in rotary mode. The study revealed the significant impact of the polyphenolic compounds concentration in cryoconcentrated OMW and the duration of tanning on the rise in the shrinkage temperature of the leather product. The shrinkage temperature of leather tanned with cryoconcentrated OMW is between 75 °C and 80 °C. Tanning with cryoconcentrated OMW produces leathers having good mechanical properties (tear strength, tensile strength, and elongation) and a darker color than that of mimosa- and chestnut-tanned leathers. Finally, cryoconcentrated OMW can be considered a new source of tannins for the ecological tanning of leather, which is aligned with the Sustainable Development Goals (SDG) adopted by the United Nations for the management of natural resources and the reduction of environmental impact, through the valorization of waste and by-products.</p>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143490151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

In the present work, activated carbon (AC) produced from coffee waste after activation with sodium hydroxide (NaOH) and pyrolysis at 800 °C (CWAC-NaOH-800) is tested as adsorbent of LIND, and as substrate for the synthesis of hybrid adsorbent/photocatalytic materials of titanium oxide with activated carbon (TiO₂/AC) via the sol-gel method, aiming at the synergistic adsorption and photocatalysis of LIND. Three different TiO₂/AC materials were synthesized at mass ratio of TiO₂ to AC equal to 2.0 (material TiO₂/AC-0.2), 4.0 (material TiO₂/AC-0.1), and 8.0 (material TiO₂/AC-0.05). As the TiO₂ to AC mass ratio increases, the specific surface area and total pore volume of the composite materials decrease, the meso-/macro-porosity are reduced and a pore-and-throat microporous network is created within the agglomerates of TiO₂ nanoparticles. The adsorption of LIND onto the CWAC-NaOH-800 is pH-independent and follows the Langmuir model with a maximum adsorption capacity equal to 9.74 mg/g. The adsorption mechanism is likely to be the hydrophobic interactions as generally ACs tend to repel water molecules and preferentially adsorb non-polar or hydrophobic compounds such as LIND. The mass transfer multi-compartment model was used to describe the LIND sorption dynamics in CWAC-NaOH-800 and TiO₂/AC-0.1, by accounting for the film/pore/surface diffusion and instantaneous linear sorption, and it was found that the contribution fraction of surface diffusion and microporosity to the total LIND sorption was enhanced with the presence of TiO₂, due to the decrease of meso-/macro-porosity. For the study of the adsorptive-photocatalytic capacity of composite materials, two experimental setups were tested and compared: an ultraviolet-A (UVA) oven with LEDs (power = 22 W, λ = 375 nm) radiating from the periphery to the center of the reactor, and a UVA lamp (power = 6 W, λ = 375 nm) radiating radially from the center to the reactor walls. The material TiO₂/AC-0.1 showed LIND sorption capacity comparable to that of CWAC-NaOH-800 and photocatalytic performance better than that of TiO₂ nanoparticles, due to the presence of AC and the \"co-adsorption\" effect. During the synergistic adsorption-photocatalysis process, the TOC removal efficiency reached 90% after 3 h of photocatalysis, which is indicative of the in situ regeneration of the material. From the inverse modeling of the adsorption-photocatalysis experiments, it was found that the kinetic constant of TiO₂/AC-0.1 photocatalyst was highest in the experimental setup of the UVA lamp, showing a good balance between adsorptive and photocatalytic capacity.</p>","PeriodicalId":545,"journal":{"name":"Environmental Science and Pollution Research","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143497661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 synthesized photocatalysts were evaluated for adsorption and photodegradation of oil well-produced water pollutants. Remarkably, the ternary heterostructure composite with 20 wt% of nr-GCN exhibited superior photocatalytic performance compared to nr-GCN and the MIL-Cr/F@S binary composite. Under visible-light illumination, the maximum removal efficiency of chemical oxygen demand for synthetic oil well-produced water reached 97.4% under optimized conditions (pH 4, illumination time 90 min, photocatalyst dosage 0.6 g/L, and pollutant initial concentration 754 mg/L). Adsorption studies revealed adherence to the pseudo-second-order kinetic and Freundlich isotherm models The ternary composite displayed degradation rates 2.8 and 2 times higher than nr-GCN and MIL-Cr/F@S, respectively. This enhanced activity was attributed to the double Z-scheme configuration, providing high specific surface area (653 m²/g), appropriate bandgap energy (1.6 eV), and efficient charge carrier separation. Moreover, the ternary photocatalysts demonstrated excellent reusability over five cycles without Cr ions leaching into the water.

However, no clear link has yet been established between alternative plasticizers and preterm births. Among these substitutes, DINCH (used as a phthalate replacement) and its metabolite, MINCH, appear to be promising options, although their health impacts remain largely unexplored. This study aims to assess the potential effects of DINCH and MINCH on the physiology of fetal membranes, focusing on the nuclear receptor PPARγ, which plays a critical role in pregnancy maintenance. An amniotic epithelial cell model was used to evaluate DINCH and MINCH influence on cytotoxicity, cell viability, and PPARγ activity, including its anti-inflammatory properties.

The initial treatment by aeration resulted in COD, color, and Abs₂₅₄ removal efficiencies of 54%, 61%, and 55%, respectively. The efficiency of the AOP was statistically evaluated, and the optimal operating conditions were determined by Box-Behnken design (BBD) to investigate the effects of three operating variables (pH, [S₂O₈^2-], and [H₂O₂]) on three target responses: COD, Abs₂₅₄, and color removal. The statistical and graphical analyses indicated that the sequential process with aeration as pretreatment and subsequent application of the HP-PS-US-UV-A system achieves cumulative maximum removal of 89% of COD, 99% of color, and 96% of Abs₂₅₄, under the optimal operating conditions of the H₂O₂/S₂O₈^2-/UV-A/US process as [H₂O₂] = 500 mg/L, [S₂O₈^2-] = 1671 mg/L, and pH = 3.

These properties, particularly yield stress and viscosity, may be significantly affected by the presence of sulfide minerals like pyrite in tailings from hard rock mines. Pyrite's oxidative capacity alters the chemistry of mixtures, impacting their rheological behavior. However, comprehensive studies on the effects of pyrite on UPT/LCPT rheology are lacking, despite their importance for effective transport and disposal. This study experimentally assesses the influence of varying pyrite concentrations (0%, 5%, 15%, and 45%) on the rheological properties of UPT and LCPT, prepared with two binder types (PCI and Slag) and analyzed at room temperature (20 °C) over curing times (0, 20, 60, and 120 min). Key assessments included yield stress, viscosity, electrical conductivity, pH, zeta potential, and microstructural analysis. Results show that pyrite content substantially affects the rheological properties of UPT and LCPT. The rheological properties of UPT increased as pyrite concentration rose, with yield stress and viscosity rising in the order of 5%, 15%, and 45% pyrite content. In LCPT mixtures, yield stress increased steadily over time with increasing pyrite content, while viscosity increased with pyrite content but decreased over time. The results also show that pyrite content causes microstructural and chemical changes in fresh LCPT, particularly, changes related to interparticle forces and inhibition of cement hydration.

The rampant destruction of natural habitats, mainly the urban wetlands in the Imphal Valley, has caused severe decline in the population of the indigenous breed. Therefore, as a part of conservation research, detailed encroachment status and impact of land use change on water quality of the urban wetlands in the Imphal Valley, i.e. Lamphel and Heingang pats, were assessed during 2022-2023. The land use/land cover analysis of the last three decades, viz. between 1988 and 2023, showed that the urban wetlands have lost 26.38 and 64.36% of its areas to human encroachment in the form of built-up or agricultural and pisciculture farms. The wetlands size got reduced by 132.3 ha for Lamphel pat and 76.8 ha for Heingang pat, respectively. Moreover, vegetation cover of the wetlands got reduced by 50.73% for Lamphel pat and 12.01% for Heingang pat, thereby forcing the pony breed to move from natural habitats. As a result, majority of pony populations today are found sheltering on busy roads of the Imphal urban region. Furthermore, the land use change has caused severe deterioration of wetland water quality. The Water Quality Index (WQI) for most of the sampling locations have WQI values in poor and unsuitable category, which unfortunately is the only source of water for the pony population in their habitat. Moreover, wetland vegetation or food plants of pony are exposed to high sodium percentage, sodium adsorption ratio, magnesium hazard and Kelly's ratio stress, which is injurious.

However, the intricate interplay of anthropogenic activities with hydrological, climatic, and fluvial processes presents significant challenges in developing robust models for predicting water quality parameters. This study develops novel deep learning (DL) models, leveraging bidirectional-LSTM (Bi-LSTM) networks and advanced ensemble-based approaches using bootstrap aggregating (BA) combined with alternating model tree (BA_AMT), to predict key water quality parameters, including daily turbidity (TU) and dissolved oxygen (DO). The proposed hybrid models were applied to the Clackamas River, USA, and their performance was benchmarked against standalone AMT models. The dataset comprised daily records of water discharge (Q), gage height (GH), water temperature (T_w), specific conductance (SC), and pH. Model performance was evaluated under six input combination scenarios to determine optimized input configurations. Results demonstrated the superior predictive accuracy of Bi-LSTM for both TU (Root mean square error-RMSE = 0.172 mg/L, Nash-Sutcliffe efficiency-NSE = 0.985, Percent of IAS-PBIAS, 0.01% and ratio of RMSE to the standard deviation of observation (RSR)-RSR = 0.11) and DO (RMSE = 1.37 mg/L, NSE = 0.713, PBIAS, 1.90% and RSR = 0.53).

Among these, Q and GH showed the strongest correlation with TU, while T_w, SC, and GH were most influential for DO prediction. While Bi-LSTM outperformed BA-AMT in overall accuracy, the BA-AMT model demonstrated superior capability in capturing extreme values.
