Despite their environmental importance, the environmental effect of BTEX remains underexplored, especially in near-road atmosphere, as most studies have focused on particulate matter and nitrogen oxides. This study continuous observed the variations in BTEX at four roadside sites under different traffic emission scenarios before and after the Spring Festival in near-road atmosphere in Shanghai, which purpose to better understand their environmental dynamics. Results indicated that BTEX and NMHCs concentrations declined substantially (41–63% and ~60%, respectively) during the Spring Festival with reduced traffic, while source apportionment using ternary diagrams and B/T ratios revealed distinct shifts from traffic-dominated to non-traffic contributions during the holiday period. However, Benzene remained at a high level and the corresponding estimated carcinogenic risk remained above the acceptable threshold in both periods. This study demonstrated that short-term traffic emission reductions not only lower VOCs levels but also significantly alter BTEX composition, but benzene still had prolonged effects, which explained that identifying BTEX from different sources is crucial for developing effective strategies to control urban environmental ozone and secondary aerosols.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"43 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145043417","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 process involves high-volume injection of hydraulic fracturing fluid (HFF) into deep rock formations, initiating a sequence of geochemical reactions that alter shale mineralogy and mobilize potentially hazardous trace elements over several timescales. These laboratory experiments reported herein explore how interactions between HFF and shale during stages of the fracking process—including the shut-in period, initial flowback, long-term gas production, and post-closure—affect the release and redistribution of a large suite of trace elements. Experimental results show that during shut-in, acid additions rapidly dissolve carbonates and sulfides, subsequently allowing sulfide oxidation; evidence of clay transformation, barite precipitation, and secondary iron mineral precipitation is seen. During the initial production phase, most elements are released via direct acid dissolution to flowback waters; oxoanion forming elements (P, As, Mo, Th) are mobilized somewhat later. These processes lead to the partial or complete loss of some trace elements (such as lanthanides, Zn and Sr) from the solid phase. Others such as As, Mo, and U are redistributed into more labile mineral forms, raising concerns about their long-term environmental mobility and potential for drinking water contamination, particularly as well networks expand and age.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"67 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145043418","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, metal oxide semiconductor sensors for TEA detection generally suffer from limitations such as sluggish response and recovery speed, limited selectivity, poor humidity resistance, and ambiguous sensing mechanisms, restricting their practical applications. Herein, SnO₂ nanofibers doped with different Cd contents were fabricated via electrospinning and calcination technologies for TEA detection. Among them, the sensor with a Cd content of 3.65 at% exhibited the highest response (R_a/R_g ≈ 32.0@100 ppm TEA), ultra-short response time (3<!-- --> <!-- -->s), good selectivity, and excellent moisture resistance at 180 °C. The enhanced performance arises from heterovalent Cd doping, which regulates the Fermi level and oxygen vacancies of SnO₂, thereby optimizing surface chemisorbed oxygen and enhancing charge transfer efficiency, significantly promoting the gas-sensing reaction. Further, density functional theory (DFT) calculations revealed the interfacial interactions, charge density distributions, and surface adsorption energies between oxygen vacancies and TEA, enabling atomic-scale analysis of the sensing mechanism in Cd-doped SnO₂ toward TEA molecules. This work demonstrates Cd-doped SnO₂ sensors' significant application potential in environmental monitoring and industrial safety systems.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"67 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145043083","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}

This study systematically compared the sulfamethoxazole (SMX) removal performance of three electrochemical CWs: microbial fuel cell CW (MFC-CW), micro-electrolysis CW (ME-CW), and electrolytic cell CW (EC-CW). Results demonstrated that SMX removal efficiency in electrochemical CWs increased by 18.6 %–33.4 % due to the synergistic effects of electrochemical oxidation, hydroxyl radical (·OH) oxidation, and microbial degradation.

Further, it promoted the formation of low-toxicity transformation products, mitigating potential ecological risks.
