The extensive administration of antibiotics across domains such as human healthcare settings, agriculture, and aquaculture farming endangers the presence of antibiotics in diverse matrices including water, soil, and air. As a result, this dissemination significantly leads to the development of antibiotic resistance in the profuse sectors of the environment further provoking consequential health implications at different trophic levels. Owing to its significance, and to mitigate antibiotic pollution and its subsequential AMR, governmental guidelines and regulations are implemented across the globe to cultivate public awareness as concerted efforts for addressing this global predicament. Given the insufficient attention to the growing antibiotic pollution issues, prompt efforts must be taken to contemplate current circumstances and the rigor of the ongoing research. In this review, we endeavor to elucidate the escalation of antibiotic concentration and antibiotic-driven AMR in water, air, and soil environments with potential public health threats.

This study presents the successful fabrication of Nb<sub>2</sub>O<sub>5</sub>-MgAl layered double hydroxide (LDH) nanocomposites for the effective removal of methylene blue (MB) and Congo red (CR) dyes via a one-step hydrothermal method. Incorporating a small amount of Nb into MgAl-LDH proved to be an effective strategy for creating nanocomposite materials with dual characteristics. The material’s morphological and crystalline structures were confirmed using FESEM-EDS and XRD. Incorporating Nb during the material preparation led to a remarkable enhancement in the material’s adsorption capacity - up to 3.4-fold and 9.0-fold increases for CR and MB, respectively. The kinetic and point zero charge analysis confirmed that the adsorption of the dyes onto the adsorbent surfaces occurred via an ionic interaction mechanism. These findings offer a promising alternative for fabricating dual-functional adsorbents, enhancing the effectiveness of dye removal in wastewater treatment technologies.</p></div>","PeriodicalId":93463,"journal":{"name":"Journal of hazardous materials letters","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666911024000029/pdfft?md5=3d98ccad5a2853187e21d5626ec0a41a&pid=1-s2.0-S2666911024000029-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139732797","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}
