The use of urease-producing bacteria (UPB) to hydrolyze urea and drive SRB to treat AMD addresses these two key limitations. Based on the pollution characteristics of AMD from an abandoned sulfur iron mine in Southwest China, this study investigates the feasibility of the combined UPB-SRB treatment for simulated AMD, explores the synergistic mechanism, and evaluates the practical application of this synergy in the treatment of real AMD. The UPB-SRB combination outperforms the individual use of UPB or SRB. When UPB neutralized the pH of simulated AMD from 2 to 5, the highest cost-effectiveness was observed: the solution’s pH increased to 7.2, with removal efficiencies for SO42-, Fe, Fe2+, and Mn2+ reaching 89.18%, 95.59%, 95.81%, and 88.2%, respectively. The reaction products of the UPB-SRB synergy included FeOOH, Fe2O3, FeS, Fe, and MnS. UPB utilized ammonia generated from urea hydrolysis to improve the acidic environment, while its metabolic by-products, including amino acids, organic acids, alcohols, and vitamin B, provided carbon and nitrogen sources for SRB. In the treatment of real AMD, the synergistic effect of UPB-SRB achieved removal efficiencies of 96.89% for SO42-, 100% for Fe, and 99.89% for Mn2+, and raised the pH from 2 to 8. The treated AMD showed no bio-toxicity or potential risks and demonstrated agricultural reuse potential. By replacing traditional carbon/nitrogen sources with urea-containing wastewater, the combined use of UPB and SRB provides an efficient, safe, and cost-effective solution for AMD disposal, offering a novel approach to optimizing SRB-based AMD treatment and urea wastewater resource utilization.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"27 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144145662","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}

However, uncertainty still exists regarding the degradation characteristics of TPhP in the presence of cadmium (Cd). Therefore, this research was conducted to elucidate the impacts of Cd on TPhP degradation in sediments. Results showed that the biodegradation efficiency of TPhP in sediments exceeded 90%. The identified degradation products of TPhP indicated that the degradation pathway primarily involved oxidative cleavage, hydroxylation, and methylation, which was further supported by condensed dual descriptors (CDD). However, the presence of Cd significantly inhibited TPhP degradation, with greater inhibition at higher concentrations of both TPhP and Cd. Transcriptomic analysis revealed that xenobiotic metabolism was significantly suppressed. Furthermore, pathways associated with cell motility, membrane transport, and energy metabolism were impaired. These disruptions likely contributed to the decreased degradation efficiency and prolonged half−life of TPhP. Interestingly, biomarkers in Firmicutes were enriched in the high−concentration TPhP + Cd treatment and strongly correlated with degradation−related gene expression, suggesting their significance in TPhP degradation under heavy metal stress. Overall, this research provides insights into the inhibitory effects of Cd on TPhP degradation and offers theoretical support for the bioremediation of TPhP−contaminated sediments with heavy metals.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"172 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144145657","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}

Shearwaters showed elevated PFAS levels, with higher ratios of C4 and C7 perfluorosulfonic acids, C7−C9 and C13 perfluorocarboxylic acids and F-53B, but lower ratios of perfluorooctanesulfonic acid and perfluoroundecanoic acid than gulls. PFAS levels in gulls were positively correlated with the body condition index, rather than δ13C or δ15N, aligning with their age (fledglings) and narrow isotopic niche.

However, the effects of organic Se on plant immunity and flowering remain poorly understood. In this study, we employed physiological, transcriptomic, and metabolomic approaches to investigate the impact of organic Se on rose plants. Our findings revealed that organic Se inhibited bud production and corolla unfolding. Individual metabolites, including jasmonic acid (JA) and glutathione (GSH), were found to significantly influence flowering. As Se concentrations increased, the levels of ABA and JA in flowers also elevated. Furthermore, Se upregulated genes involved in the pentose phosphate cycle (e.g., galm and idnk), and metabolites such as D-gluconate and glucose, which are early signals for flower induction. Phytohormones were observed to regulate sugar metabolism, linking Se-induced changes to flowering processes. Se application also altered linoleic acid and α-linolenic acid metabolism, affecting JA synthesis. Key genes encoding LOX2S (Rru01G000760, Rru05G070200, Rru05G070220) and AOS (Rru06G051490) were significantly upregulated. Interestingly, metabolites that increase disease resistance were found to inhibit flowering, suggesting that abnormal flowering may be a plant response to stress resistance. Moreover, low concentrations of Se promoted photosynthesis, with the upregulation of genes encoding NADH dehydrogenase, petA, Ppa, petC, petH, and ATPF1G. Se also modulates antioxidant enzymes, phytohormones, and key metabolites, which are critical signaling molecules in the regulation of disease resistance. These findings provide a scientific basis for the application of organic Se in green agriculture and crop health improvement.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"57 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144145596","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}

The sensor exhibits a rapid response, high selectivity, high sensitivity, and a large Stokes shift. Both experimental and theoretical calculations indicate that PFOA/PFOS induced aggregation of the sensor ES through electrostatic and hydrophobic interactions, thereby activating its aggregation-induced emission (AIE) effect. The sensor ES can be further utilized for the detection of PFOA/PFOS in real water samples, and a portable smartphone-based analyzer system has been developed for rapid on-site detection. In addition, ES demonstrates low biotoxicity, which enhances its applicability in detecting PFOA/PFOS in living cells, zebrafish, and mice.

This study investigates the spatiotemporal accumulation and mobility of arsenic and thallium in stream sediments under seasonal runoff variations. The results showed that runoff variations during the normal season (NS) and wet season (WS) significantly influence arsenic and thallium concentrations and mobility in stream sediments at the mining watershed. Elevated water levels during NS and WS increased As and Tl concentrations in sediments to 4.49-7.45 times and 0.52-1.09 times compared to dry season (DS), respectively. Furthermore, As predominantly accumulated in surface sediments (0-20 cm depth), whereas Tl showed greater enrichment in deeper layers (20-60 cm). Notably, active fractions of As and Tl in the upper sediment layer (10-20 cm) during NS and WS were 2-8% higher than those observed in the DS. Fine sediment particles (50-250 µm) serve as the key transport medium for As and Tl during NS and WS, demonstrating 6-21% higher active fractions compared to DS. Increased runoff velocity reduced channel contamination duration from 57.12 h in the DS to 12.96 h and 4.8 h in the NS and WS, respectively, with the highest potential risk occurring in stream curved zones. Runoff-induced hypoxic conditions elevated As and Tl concentrations in sediment porewater during NS and WS, which quinone-mediated organic matter transformation and acidophilic microbial community biogeochemistry were identified as primary regulators of As and Tl mobility.

Furthermore, the sensing mechanism of the RFID tag sensor was investigated in terms of the field-effect transistor (FET) transfer curve and antenna reflection coefficient. The charge density in the sensing component was altered by Pb2+, reducing resistance and modifying the tag antenna impedance. Impedance mismatch between the antenna and RFID chip was thereby induced, with varying degrees of mismatch directly altering the light-emitting diode (LED) luminous intensity on the tag sensor. Rapid detection (<2 s) via luminous intensity monitoring eliminated a vector network analyser (VNA), achieving a detection limit of 1.96 μg/L.
