With a maximal EDA conversion of 82 % and EU selectivity of 99 % at 160 °C for 2 h, Mn₂O₃ catalysts had the best catalytic activity among them, which was superior to the reported catalysts. In the following order: Mn₂O₃ &gt; MnO₂ &gt; Mn₃O₄, the catalytic activity for the synthesis of EU from CO₂ and EDA decreased. Further characterization showed the Mn₂O₃ catalyst possessed a greater Mn³⁺/Mn⁴⁺ ratio and more surface oxygen vacancies than the MnO₂ and Mn₃O₄, which improved its capacity to adsorb and activate CO₂ and EDA. After four recycling runs, the EDA conversion slightly declined from 82 % to 56 % on Mn₂O₃ catalyst, while no obvious change in EU selectivity was observed. The loss of surface O_v contents and Mn³⁺ proportion were concluded as main reasons for the decrease in catalytic activity over Mn₂O₃ catalyst.

These composite pollutants can migrate rapidly with water flow, which are usually difficult to degrade and remove by traditional methods. Aiming at suspended contaminated waterbodies, this study introduced a multilevel loading method to prepare carbon nanotube/sulfur doped carbon nitride (CNT/SCN) composite photocatalytic purification beads. The surface of the obtained core-shell structured purification beads is loaded with CNT/SCN photocatalysts which exhibit three-dimensional conductive and porous characteristics. TC<img>HCl was introduced as the target pollutant, and the removal efficiency of the composite purification beads under different water turbidity and hydrodynamic conditions were investigated. The results showed that during 15 h of degradation process, at the depth of 20 cm, with the flow rate of 0.015 m³/h and water turbidity of 10.3 NTU, the purification beads achieved a removal efficiency of 54.9% for tetracycline hydrochloride (TC<img>HCl), which was 2.03 times higher than that of SCN purification beads. The three-dimensional porous structure of the surface exhibited excellent adsorption and trapping capabilities for suspended colloidal particles. The introduction of carbon nanotubes enhanced charge transfer ability of the surface layer and reduces the local charge accumulation effect caused by surface adsorption, which effectively enhances the adsorption of suspended colloid, and also significantly improved the degradation efficiency of TC<img>HCl.

In this study, we investigated the impact of NPs at concentrations found in the environment on the gut flora, intestinal barrier function, liver pyroptosis, and inflammation in mice following 12 weeks of exposure. To further validate the involvement of gut flora in inflammatory liver damage caused by NPs, we utilized antibiotics to remove the intestinal flora and performed fecal microbiota transplantation. We confirmed that NPs exposure altered the gut microbiota composition, with a notable rise in the proportions of <em>Alloprevotella</em> and <em>Ileibacterium</em> while causing a decrease in the relative proportions of <em>Dubosiella</em>. This disruption also affected the gut barrier, increasing lipopolysaccharides in circulation and promoting liver pyroptosis. Importantly, mice receiving fecal transplants from NPs-treated mice showed intestinal barrier damage, liver pyroptosis, and inflammation. However, NPs effects on the intestinal barrier and liver pyroptosis were attenuated by antibiotics depletion of the commensal microbiota. In summary, our current research revealed that extended exposure to environmentally relevant concentrations of NPs resulted in inflammatory damage to the liver. Additionally, we have identified for the first time that imbalances in intestinal flora are crucial in liver pyroptosis induced by NPs.</div></div>","PeriodicalId":15788,"journal":{"name":"Journal of Environmental Sciences-china","volume":"155 ","pages":"Pages 250-266"},"PeriodicalIF":5.9,"publicationDate":"2024-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143158382","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Special emphasis was paid on the analysis of thermal effects through a robust modeling approach.

The thermal activation of PDS mainly occurred near the hole where the fitting temperature was around 340 K, while •OH was generated in the bubble collapse region downstream the hole, where the temperature was much higher and favorable for the cleavage of water molecular. The average temperature under different external physical conditions was in good consistence with the degradation rates.

During the wet weather, the concentrations of most investigated ECs, e.g., microplastics, per- and polyfluoroalkyl substances, and vehicle-related compounds, significantly increase in surface water, indicating that stormwater may be a critical source of these contaminants. Furthermore, the potential pathways of ECs from stormwater enter surface water are outlined. Studies demonstrate that surface runoff and combined sewer overflows are important pathways for ECs, with discharges comparable to or exceeding those from wastewater treatment plants. Illicit connection also plays an important part in elevated EC concentrations in surface water.

However, knowledge gaps remain in the bromination processes of emerging phenolic pollutants in plants, which may increase the potential health risk associated with food exposure. Our study discovered that light induced generation and accumulation of more toxic brominated organic compounds (Br-org) in lettuce leaves under the stress of acetaminophen (ACE) than that without light, as evidenced by an increase in C-Br bond intensity in FTIR analysis. This result can be explained by the oxidation of bromide ions (Br^-) by reactive species (ROS and ³Chl*) of chloroplast into reactive bromine species (RBS). The main mechanism is that the redox of Br^- reduced the oxidative damage of ACE to the structure and function of chloroplasts, providing good conditions for light energy uptake and utilization and promoting the increase of pigments and active species. Compared with the dark group exposed to 5 mg/L Br^-, the pigment content, H₂O₂ and ¹O₂ level of the light group increased by 56%, 84% and 69%, respectively. On the other hand, RBS attacks certain electrophilic organic compounds in leaves to generate Br-org. Triple excited state of chlorophyll (³Chl*) was the dominant species for the transformation of ACE, while RBS is a key factor in the generation of Br-org in the Br^-/light/chlorophyll system. A total of six transformation products were identified by HPLC-MS/MS, which were involved in three transformation pathways: methylation, hydroxyl oxidation and hydroxylation followed by bromination. This is the first report that Br^- could enter the chloroplast and improved chloroplast structure under ACE stress, and elucidated the bromination mechanism of organics in terrestrial plant involving of biophotochemical bromination in chloroplast besides enzyme-catalyzed bromination.

As observed, a rapid and complete mitigation 100 mg/L of tylosin was achieved within 15 min by the catalysts. Acidic cleavage of tylosin was fulfilled by sulfonic groups in the composites, and microwave thermal accelerated the hydrolysis reactions due to the dielectric and magnetic-loss effects. Differentiating the dielectric and magnetic-loss effects through electromagnetic analyses indicated that the latter contributed more in converting microwave energy to heat. The interactions under multiple operational conditions were quantitatively fitted using the Behnajady model and visually demonstrated, which indicated that a synergic effect of microwave thermal- and acidic-hydrolyses contributed to the efficient mitigation of tylosin. The transformation products were identified and the pathways were supposed. Cleaving deoxyaminosugars groups and destructing lactone structures led to reduced antibacterial potential and toxicity reduction.
