The oxidative metabolism of CPs by fish is an important pathway for the degradation of CPs present in aquatic ecosystems. However, the factors affecting the oxidative metabolism of CPs by fish are poorly understood, with only a few studies having examined CP metabolites in fish; research that focuses on fish from the natural environment is even more scarce. In the present study, single and mixed CP standards were incubated in vitro with fish liver microsomes to study the formation of CP metabolites. In addition, the presence of CPs and associated metabolites were analyzed in marketable freshwater fish. The in vitro fish liver microsome experiments showed the metabolic elimination ratio of short-chain CPs ≈ medium-chain CPs > long-chain CPs. Both mono- and di-hydroxylated oxidative metabolites of CPs were identified. Importantly, although both monohydroxylated CPs (monoOH-CPs) and CP ethers were detected in the tested marketable fish, only monoOH-CPs were confirmed as oxidative metabolites of CPs; moreover, a large amount of false positive C14H24Cl6 was detected. This study provides valuable insights into the biotransformation of CPs in fish. The results highlight the importance of chromatographic separation when analyzing CPs and associated metabolites in fish. Further, assessments of the ecological/health risks of CPs should pay special attention to monoOH-CPs since these species may have higher toxicities than the parent compounds.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"24 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143418177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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 comprehensive approach combing biochemical analyses and multi-omics techniques was employed to investigate the mechanisms underlying amantadine-induced toxicity in L. japonica gametophytes. The development rate of algal cells was less than 3 % from 103 to 107 ng/L of amantadine.

Key genes (e.g., SOD2) and metabolites (e.g., arachidonic acid and α-linolenic acid), associated with the antioxidant system and arachidonic acid metabolism, were identified, leading to oxidative stress in the algae. Furthermore, the downregulation of genes and metabolites involved in porphyrin metabolism, photosynthesis, carbon fixation, glycolysis, and the pentose phosphate pathway may inhibit ATP supply and NADPH generation, negatively affecting metabolic processes and inhibiting algal cell growth. In contrast to disrupting protein synthesis in juvenile sporophytes, amantadine primarily interferes with photosynthesis and carbohydrate metabolism in gametophytes.

Improving the sulfur capacity of H2S is a crucial challenge to reduce the operation cost. NiFe layered double hydroxide (LDH) adsorbents were synthesized using the hydrothermal method to strengthen the adsorption of H2S, achieving a high sulfur capacity of 133.6 mg/g at 50 °C. Characterization studies have revealed that the reaction pathway of H2S on the NiFe LDH surface involves adsorption, dissociation and oxidation. It has been clarified that the high sulfur capacity can be attributed to the abundant H2S dissociation sites and the excellent O2 activation sites. The dissociation sites of H2S encompass metal sites, -OH and CO32-. The interaction between O2 and the bridge site of asymmetric metal atoms significantly enhances the dissociation of O2. Strengthening the dissociation of H2S and O2 improves the sulfur capacity. The deactivation of adsorbents comes from the continuous consumption of oxygen species mainly composed of -OH and the deposition of sulfur species in the smaller mesopores ranging from 2-10 nm. This work provides useful insights into designing highly efficient iron-based adsorbents for the desulfurization of blast furnace gas.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"63 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143417665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Nonlinear interfacial rheology was used to quantitatively distinguish effects of nanoparticles at different stages of breathing cycles. Oscillation studies which simulated the breathing cycles in different human ages showed that both crystalline structures of TiO2 nanoparticles made nanoparticles-dipalmitoyl phosphatidylcholine (DPPC) system more viscous, dissipative and irreversible during the oscillations, thus affecting the normal operation of lung surfactant. At the least concentration of nanoparticles studied, i.e., 0.01 wt %, the anatase ones significantly affected the expansion part of the cycle, whereas the rutile ones affected both expansion and compression phases. Interactions between DPPC and TiO2 nanoparticles under dynamic conditions of breathing cycles were affected by the crystalline structures and concentrations of nanoparticles and breathing conditions, with key factors including physical properties, such as sizes, shapes, and zeta potentials of nanoparticles.

The results demonstrated that high doses of PE-MPs significantly inhibited S. nigrum growth and reduced Cd concentration and accumulation in plants. Meanwhile, the decrement of bioavailable Cd content and the formation of C-H and -COO in rhizosphere soil were observed with the presence of PE-MPs. The simultaneous exposure of PE-MPs and Cd caused the significant increase in the proportions of Proteobacteria and Acidobacteriota, indicating that certain PE-degrading microorganisms may play a pivotal role in aforementioned processes. More importantly, the relative abundance of the genera Pseudolabrys, DEV008, and Flavobacterium was significantly elevated, likely contributing to the response of S. nigrum to combined toxicity. Co-exposure caused a significant downregulation of biosynthetic processes, involving carbohydrates and adenosine. Additionally, the biosynthesis of ABC transporters, phenylpropanoids, flavonoids, and organic acids was also significantly affected.

Covalent organic frameworks (COFs) have emerged as promising candidates for amine sensing due to their exceptional stability when exposed to corrosive amines. While several COF-based sensors have recently been developed for amine detection, to the best of our knowledge, fluorescent “turn-on” sensors have been limited to imine-linked COFs. However, the relatively low stability of imine linkages may compromise structural integrity in the presence of corrosive amines. Here, for the first time, we constructed a cationic C−C single bond linked COF (CSBL-COF-4) through the reaction between cationic porphyrin TMPyP and terephthaldicarboxaldehyde. The abundant cationic sites distributing throughout the networks not only improved the dispersity of CSBL-COF-4 in aqueous solution but also provided numerous acidic sites to enhance the affinity with alkaline amines via Lewis acid-base interaction. CSBL-COF-4 exhibited an efficient response to amine solutions or vapors and was further utilized to evaluate the freshness of meat samples, highlighting its potential for practical applications. Our result would thus open up a new avenue towards constructing a broader class of COF-based sensors for the fluorescence “turn-on” detection of amines.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"62 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143401375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}
