Wastewater is one of the major crises in depletion of the environment. Photocatalysis is considered as the best way to remove pollutants. Therefore, in this study, pure and g-C₃N₄-SnWO₄ nanocomposites were produced employing hydrothermal route. Prepared composites were studied by various techniques. SnWO₄ band gap were altered by introduction of g-C₃N₄. The morphology was uniformly developed by the addition of g-C₃N₄ to the SnWO₄. Evans Blue dye was employed as model pollutant. The photocatalytic action was improved by adding g-C₃N₄, which formed a heterojunction with SnWO₄. The calculated rate constant was 0.000878, 0.0068, 0.01 and 0.0122 min^-1 for EB, SnWO₄-EB, 0.1g g-C₃N₄-SnWO₄-EB and 0.2g g-C₃N₄-SnWO₄-EB. The rate constant increased for 0.2 g g-C₃N₄-SnWO₄ photocatalyst. A heterojunction appeared between g-C₃N₄ and SnWO₄ facilitated SnWO₄ for better e^-/h⁺pair's separation and a lower recombination rate, which increased photocatalytic action of product. 0.2 g of g-C₃N₄-SnWO₄ is a promising candidate for future wastewater degradation.</p>","PeriodicalId":93933,"journal":{"name":"Chemosphere","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142607759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Effects of biochar on the dissipation of tobacco alkaloids in soil-crop systems remain poorly understood. In this study, a 40-day pot experiment was conducted to explore the effect of cow dung biochar (CDBC) and maize straw biochar (MSBC) on the uptake of nicotine and nornicotine by pea (Pisum sativum L.) and their dissipation in an agricultural soil. The results revealed that the bioaccumulation of nicotine and nornicotine by pea shoots in the soils added with CDBC and MSBC at 1.5% and 3.0% significantly decreased by 46.97-79.13% and 33.64-71.59%, respectively. CDBC more effectively decreased the uptake and bioaccumulation of nicotine and nornicotine by pea shoots than MSBC due to the higher soil pH and nutrient content. In addition, the enhanced relative abundances of soil nicotine-degrading bacteria belonging to the genera Arthrobacter and Gemmatimonas also contributed to the decreasing uptake of nicotine by pea plants. The decreased bioavailability in the soils due to the increased adsorption was the key factor for the reduced bioaccumulation of tobacco alkaloids.

Historic emissions and the subsequent atmospheric deposition of perfluorooctanoic acid (PFOA) and GenX (hexafluoropropylene oxide-dimer acid / HFPO-DA) from the FCPP have resulted in the nearby environment being contaminated with per- and polyfluoroalkyl substances (PFASs). This research aimed to investigate the levels of PFASs in garden produce and whether a gradient can be observed in relation to distance from the FCPP. Furthermore, differences between certain types of fruits and vegetables were explored, as well as a potential relation between the measured concentrations in garden produce and soil. 737 fruit and vegetable samples were collected from 17 allotments and 4 gardens up to 20 kilometres from the FCPP, along with soil and water samples. Garden produce included fruits, potatoes, fruiting vegetables, brassicas, leafy vegetables, root vegetables, bulb vegetables, legumes and stem vegetables. PFASs concentrations in the samples were quantified using a very sensitive UPLC-MS/MS method. PFASs were detected in most samples above the analytical limit of detection (0.3 to 12.5 pg/g ww). PFOA and GenX were found in the highest concentrations (up to 5280 pg/g ww GenX and 3020 pg/g ww PFOA) in garden produce sampled downwind and close to the FCPP. Other PFASs were also found, but at (much) lower levels. Field-derived bioaccumulation factors (BAFs) were calculated for PFOA and GenX. The BAFs for PFOA were shown to be approximately 1 order of magnitude lower than BAFs from other studies. This may be explained by aging of the PFASs contamination and the intense cultivation of the garden plots. This study shows that PFOA and GenX can end up in garden produce and this will result in human exposure when the garden produce is consumed.</p>","PeriodicalId":93933,"journal":{"name":"Chemosphere","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142549445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Efforts to evaluate and implement MP removal processes are underway, with membrane technologies often recommended as an \"ideal\" solution. A key challenge in evaluating these technologies involves efficiently quantifying MP concentrations in samples. Here, flow cytometry (FC) is demonstrated as an effective technique to obtain concentration measurements of plastic microbeads (MBs; 1-5 μm) suspended in water with/without added humic acid. Regardless of solution conditions, MB concentrations were easily quantified via FC. Subsequently, two microfiltration membranes were challenged to these suspensions. As measured via FC, the 0.45 μm membrane demonstrated effective MB rejection (>99%) whereas the 5 μm membrane exhibited a broad range of rejections (40% to >95%) depending on solution conditions and filtration time. Finally, a model was formulated utilizing FC forward light scattering intensity measurements to estimate MB sizes in samples. Using the model, a 33% reduction in median MB size, on average, was noted across the 5 μm membrane when filtering MBs suspended in humic acid solution, affirming a preferential permeation of smaller particles.

Here we used RNA-sequencing to characterize persistent hepatic transcriptional effects one week after the conclusion of five weeks oral exposure to 10 mg/kg/day or 100 mg/kg/day DBP in male mice. The exploratory transcriptome analysis demonstrated five differentially expressed genes (DEGs) in the 10 mg/kg/day group and thirteen in the 100 mg/kg/day group. Gene Set Enrichment Analysis (GSEA), which identifies affected biological pathways rather than focusing solely on individual genes, revealed nine significantly enriched Reactome pathways shared by both DBP treatment groups. Additionally, we found 54 upregulated and one downregulated Reactome pathways in the 10 mg/kg/day DBP group, and 29 upregulated and 13 downregulated pathways in the 100 mg/kg/day DBP group. According to the DEGs and the GSEA findings DBP exposure disrupts several key biological processes, including protein translation, protein folding, apoptosis, hedgehog signaling, degradation of extracellular matrix and alterations in the energy/lipid metabolism. Subsequent liver tissue analysis corroborated these findings, showing that DBP exposure induced tissue disorganization, oxidative stress, lipid accumulation, increased TNF-α, ATP and glucokinase levels. In addition, several proteins central for the metabolic system were affected, mostly in a dose-response pattern.

This study investigated the toxicity of three single BPs and their mixtures' effects on the survival of Daphnia magna.

Bismuth oxyiodides (BiOI), which are known for their visible-light photocatalytic properties, demonstrate considerable potential for removal of pharmaceutical pollutants. This study examines the synthesis and performance of BiOI-based composites with barium ferrite (BFO) nanoparticles for enhanced PMS activation under visible light. BiOI and Bi₅O₇I were synthesized via solvothermal and electrodeposition methods, respectively, and their morphologies and crystalline structures were observed to exhibit distinctive characteristics following annealing. The formation of the composite with BFO resulted in an improvement in the catalytic properties, which in turn enhanced the surface area and availability of active sites. The objective of the photocatalytic studies was to evaluate the degradation and mineralization of tetracycline (TC) under visible light, PMS, and combined conditions. The Bi₅O₇I(ED)-BFO catalyst was identified as the optimal candidate, achieving up to 99.8% TC degradation and 99.4% mineralization within 90 min at room temperature. The synergistic effect of BFO in BiOI-based composites significantly enhanced performance across all conditions, indicating their potential for efficient remediation of pharmaceutical pollutant. The material's performance was further evaluated in tap water, where the degradation efficiency decreased to 56.4% and mineralization to 38.2%. These results reflect the challenges posed by complex water matrices.
