Magnesium oxide nanoparticles (MgONPs) are non-toxic, eco-friendly, and highly stable materials that have wider opportunities for their production at the nanoscale. Differently synthesized MgONPs have been found to induce plant resistance against these stresses <em>via</em> a combination of physiochemical and molecular pathways that strengthen the structural barriers, improve nutrient availability, osmoregulation, photosynthetic efficiency, hormonal regulation, activate antioxidant defense systems, stress-responsive genes, thereby enable plant adaptation to environmental stressors.

Various herbicides belong to the frontline agrochemicals. Trifluralin is one of them. Although the use of herbicides can drastically increase the production of foodstuffs, the widespread use of these organo-toxins increases the concern for food safety and human health security. Hence, it is imperative to detect their presence and accurately measure their concentrations in food products. To overcome these challenges, herein, for the first time, we have constructed a reusable and environment friendly nanoscale Hf(<small>IV</small>)–organic framework (<strong>1</strong>) which can act as a selective sensor and promising adsorbent for one of the most widely used herbicide, trifluralin. In addition to rapid response time (&lt;5 s) and ultralow detection limit (LOD = 16.3 nM) for trifluralin, this innovative framework material is capable of detecting and quantifying the targeted herbicide across a diverse range of environmental soil and water samples and multiple pH media. Moreover, the current MOF also serves as an exceptionally effective adsorbent for trifluralin from aqueous media. Its distinctive features include a remarkably short equilibrium time (&lt;5 min), an unprecedentedly high adsorption capacity (164 mg g<small>⁻¹</small>) and the ability to adsorb trifluralin efficiently even in the presence of various other contaminants such as metal ions, anions, and other herbicides. This remarkable adsorption capability remains preserved in a wide range of environmental water sources and diverse pH levels. Furthermore, for the first time, MOF@starch@cotton composites have been fabricated utilizing the biopolymer starch as a binding agent. These composites have been successfully employed for both visual nanomolar-level determination and efficient adsorption of trifluralin. The most possible reason behind selective sensing and adsorption was deeply investigated with the help of appropriate analytical tools and theoretical simulations.</p>","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":null,"pages":null},"PeriodicalIF":5.8,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141495699","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}

We assessed potential toxic effects of repeated oral exposure to silver nanoparticle (AgNP) embedded nanocomposites and compared them to individual component materials using a transparent strain of the fish model Japanese medaka (<em>Oryzias latipes</em>).

Adult fish were exposed to AgNPs, silver nitrate, abraded PETG microplastics, or abraded nanocomposites <em>via</em> 7 oral gavages over the course of 2 weeks. <em>In vivo</em> observations showed alterations in the liver and gallbladder of fish exposed to pristine AgNPs and nanocomposites.

Similarly, alterations of the head kidney were also observed in fish exposed to silver and its composites, with both tubules and glomeruli affected. In both of these organs, many of the changes occurred adjacent to large blood vessels, suggesting material translocated from the bloodstream to adjacent tissues. TEM of the liver supported histological findings, with increased glycogen as well as hepatocellular swelling and abundant lipid vesicles in exposure groups.

However, the underlying mechanism of microRNAs (miRNAs) in regulating transgenerational nanoplastic toxicity remains largely unclear. We aimed to determine the miRNA-mediated mechanism for the induction of transgenerational nanoplastic toxicity. In <em>Caenorhabditis elegans</em>, although germline RNAi of both <em>mir-240</em> and <em>mir-36</em> suppressed polystyrene nanoparticle (PS-NP) toxicity, exposure to PS-NPs (1–100 μg L<small>⁻¹</small>) only increased <em>mir-240</em> expression.

Among the predicted target genes of <em>mir-240</em> in the germline, the exposure to PS-NPs (1–100 μg L<small>⁻¹</small>) decreased <em>rab-5</em> and <em>rab-6.2</em> expressions, whereas the germline RNAi of <em>mir-240</em> only increased <em>rab-5</em> expression in PS-NP exposed nematodes.

Here, 50 mg kg<small>⁻¹</small> cerium oxide (CeO<small>₂</small>) NMs had the greatest promotion on carrot growth, and 5 days was the initial time for promoting taproot thickening. The application of CeO<small>₂</small> NMs to soil first stimulated the secretion of organic acids, amino acids, fatty acids, phenols, and carbohydrates (such as citric acid, asparagine, and alpha-linolenic acid), as well as growth regulators indole-3-acetic acid (IAA) and jasmonic acid, from the roots to the rhizosphere.
