The proposed PDC-ERH with hydraulic circulation showed overall improvement in heating performance and energy efficiency, as well as migration and removal of nitrobenzene. This new system improved the uniformity of PDC heating and achieved a temperature increase of ∼15°C compared to that using conventional alternating current (AC) of same voltage. Nitrobenzene migration out of the low permeability zone (LPZ) was intensified by the dual effects of heat-induced diffusion enhancement and electric field-induced electroosmotic flow, while subsequent removal was enhanced by electrochemical degradation and volatilization.

In addition, the concentrations of Cl-PFESAs in toilet paper were significantly higher than that in tissue (<em>p</em> < 0.05). However, no significant differences were observed in the concentrations of PFASs in tissue and toilet paper from different materials and origins. This suggests that PFASs, particularly emerging PFASs, are widely detected in tissue and toilet paper products across China, and their presence is a potential source of landfill contamination and human exposure.</p></div>","PeriodicalId":93463,"journal":{"name":"Journal of hazardous materials letters","volume":"5 ","pages":"Article 100109"},"PeriodicalIF":0.0,"publicationDate":"2024-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S266691102400008X/pdfft?md5=c09cb73bcc04b9742f6bb2998617ca08&pid=1-s2.0-S266691102400008X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140344709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
