Here we hypothesized that polystyrene microplastics could enhance the phototransformation of silver chloride nanoparticles and modify their toxicity. We conducted phototransformation of silver chloride nanoparticles with polystyrene microplastics under light irradiation. The photo-dissolution of silver chloride nanoparticles and photo-reduction of silver ions were determined in both double-distilled-water and environmental waters. We found that polystyrene microplastics highly enhanced the phototransformation of silver chloride nanoparticles by hydroxyl radicals, singlet oxygen, and triplet state microplastics, leading to the release of silver ions and chloride ions. Subsequently, the silver ions were reduced to silver nanoparticles by superoxide radicals. Consequently, the silver species transformation increased the toxicity of silver chloride nanoparticles even at environmental concentration, as evidenced by survival rate of zebrafish larvae reduced from 100% to 23.3%. This is the first study to show that polystyrene microplastics can enhance the phototransformation of silver chloride nanoparticles to silver nanoparticles, thereby increasing the environmental risks of silver chloride nanoparticles in environmental waters.</p></div>","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"23 1","pages":"13 - 19"},"PeriodicalIF":15.0,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142397703","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}

Separation science techniques including sample preparations and chromatography require large amounts of solvent and power to separate, identify, and quantitate pure constituents from their matrices. Recent advancements to green analytical chemistry have now provided comprehensive metrics, such as the analytical method greenness score (AMGS), that allow researchers to better understand their method’s environmental burden, compare it to other methods, and indicate what areas can be addressed to enhance sustainability. Here, we review approaches and technologies that can be used to green analytical separations with a focus on improving the method’s analytical figures of merit. Approaches to green sample preparation are first considered including microextraction techniques in liquid, solid, and supercritical phases and the ability to automate such techniques. We focus on high-performance liquid chromatography and sub- or super-critical fluid chromatography, where it is shown that changing the column dimensions and packing can reduce environmental impact while preserving chromatographic resolution. We review equations to calculate the greenest flow rate at which to operate a separation method, then we discuss of modern ultrafast and high throughput separations. Finally, we describe digital signal processing for analytical signals as a major green technology for the first time. We observed that, using digital signal processing, an ultrafast liquid chromatographic separation of 101 components in just one minute produced an AMGS of 0.12 which is, to our best knowledge, the lowest ever reported.</p></div>","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"22 6","pages":"2753 - 2775"},"PeriodicalIF":15.0,"publicationDate":"2024-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142377263","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}

Photocatalysis utilizing semiconductors like graphitic carbon nitride (g-C₃N₄) is cost-effective for antibiotic degradation, however its efficiency is limited by rapid charge carrier recombination. This can be mitigated by forming heterojunctions with compatible semiconductors. Metal oxides, commonly employed for this purpose, are typically deposited on g-C₃N₄ surfaces, and often agglomerate, resulting in uneven distribution and reduced number of active-sites. Here we present a facile approach for in situ polymerization of g-C₃N₄ sheets onto bimetallic oxide surfaces, facilitating their seamless integration. CoNiO₂ was utilized as substrate for growth of g-C₃N₄, which improved crystallinity and surface area of g-C₃N₄-CoNiO₂ composite. Optimized g-C₃N₄-CoNiO₂-3% achieved a tetracycline degradation efficiency of 95.6%, markedly exceeding 61.3% degradation observed with pristine g-C₃N₄. Extended X-ray absorption fine structure spectroscopy confirmed synergistic interaction between CoNiO₂ and N-coordinating sites of g-C₃N₄ by interfacial Ni–N₂ bond, enhancing electron transport. This interaction is further evidenced by energy-resolved distribution of electron trap patterns from reversed double-beam photoacoustic spectroscopy, which reveal that while g-C₃N₄ displays significant electron trap density peaks around 2.7–2.9 eV. The g-C₃N₄-CoNiO₂ enhances this density, indicating formation of an electrical interface heterojunction that improves electron and hole migration across interfacial boundary. Electron spin resonance measurements confirmed that superoxide anion radicals and holes were main active species in promoting tetracycline degradation. Integration of g-C₃N₄ with bimetallic oxides enhances antibiotic degradation efficiency, presenting a promising and impactful strategy for environmental remediation.</p></div>","PeriodicalId":541,"journal":{"name":"Environmental Chemistry Letters","volume":"23 1","pages":"33 - 39"},"PeriodicalIF":15.0,"publicationDate":"2024-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142276729","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}
