Herein, geopolymers were prepared using TMT, FS and flue gas desulfurization gypsum (FGDG) to immobilize heavy metals, and their compressive strength and heavy metal leaching toxicity were investigated. It was first determined that T4F5 (TMT:FS = 4:5) sample exhibited the highest compressive strength (7.83 MPa). T4F5 achieved 95% immobilization efficiency for As and Cr, and nearly 100% for Cu, Zn and Mn, showing good immobilization performance. A series of characterization analyses showed that heavy metal cations can balance the charge in the geopolymer and replace Al in the geopolymer structure to form covalent bonds. In addition, about 2%–20% of heavy metal Fe was immobilized in hydration products, heavy metal hydroxides and non-bridging Si–O and Al–O coordination with silica-aluminate matrices. AsO<sub>3</sub><sup>3−</sup> was oxidized into AsO<sub>4</sub><sup>3−</sup>, which may form Ca–As or Fe–As precipitates. Cr<sub>2</sub>O<sub>7</sub><sup>2−</sup> was converted to CrO<sub>4</sub><sup>2−</sup> under alkaline environment and then combined with OH<sup>−</sup> to form Cr(OH)<sub>3</sub> precipitates. Mn<sup>2+</sup> may react directly with dissolved silicate to form Mn<sub>2</sub>SiO<sub>4</sub> and also form Mn(OH)<sub>2</sub> precipitates. The unstable Mn(OH)<sub>2</sub> can be further oxidized to MnO<sub>2</sub>. The heavy metal cations were immobilized in the silicoaluminate lattice, while the anions tended to form insoluble precipitates. These results may benefit the industry and government for better handling of TMT, FS and solid wastes containing the abovementioned five heavy metals.\u0000</p>","PeriodicalId":12720,"journal":{"name":"Frontiers of Environmental Science & Engineering","volume":"144 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2024-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139555184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Additionally, compared to original NPs, photodegraded NPs would pose higher toxicity. This is because their relatively higher specific surface areas and the presence of additives which can more easily leach. How original NPs and aged NPs affect plant growth has not been widely investigated. This work chose polyvinyl chloride NPs (PVC-NPs) that were subjected to up to 1000 h UV light radiation to explore the impact of PVC-NPs on the growth of pea seedlings (<i>Pisum Sativum</i> L.). The results indicated the existence of PVC-NPs with longer UV light radiation time and higher concentrations had more negative influences on pea seedlings’ growth such as germination rate (decreased by 10.6%–22.5%), stem length (decreased by 2.8%–8.1%), dry weight (decreased by 6.3%–7.1%) and fresh weight (decreased by 6.7%–14.8%). It was also noted that photodegraded PVC-NPs resulted in damage to leaf stomata and roots, hindering photosynthesis and absorption of nutrients and hence the decrease in chlorophyll and soluble sugar contents. According to transcriptomic investigation results, the presence of aged PVC-NPs primarily influenced protein processing in endoplasmic reticulum (upregulated metabolic pathway) and phenylpropanoid biosynthesis (downregulated metabolic pathway) of pea seedlings. These results provide an in-depth understanding of how NPs influence the growth of plants.\u0000</p>","PeriodicalId":12720,"journal":{"name":"Frontiers of Environmental Science & Engineering","volume":"172 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2024-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139471079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Wastewater treatment plants (WWTPs), acting as a link between human activities and the environment, create ideal conditions for the selection and spread of antibiotic resistance genes (ARGs) and antibiotic-resistant bacteria (ARB). Unfortunately, current treatment processes are ineffective in removing ARGs, resulting in the release of large quantities of ARB and ARGs into the aquatic environment through WWTP effluents. This, in turn, leads to their dispersion and potential transmission to human through water and the food chain. To safeguard human and environmental health, it is crucial to comprehend the mechanisms by which WWTP effluent discharge influences the distribution and diffusion of ARGs in downstream waterbodies. In this study, we examine the latest researches on the antibiotic resistome in various waterbodies that have been exposed to WWTP effluent, highlighting the key influencing mechanisms.
