High‐density polyethylene microplastics in agricultural soil: Impact on microbes, enzymes, and carbon‐nitrogen ratio

Journal of Environmental Quality, Journal Year: 2024, Volume and Issue: 53(5), P. 711 - 726

Published: July 28, 2024

Abstract Microplastics (MPs), recognized as emerging pollutants, pose a significant threat to diverse organisms and have adverse effects on agricultural soil. High‐density polyethylene (HDPE) holds prominent position among prevalent forms of MPs. In the current investigations, impact HDPE was assessed at four different concentrations (0.25%, 0.5%, 0.75%, 1.0%) soil, microbial population, exoenzymes activities including amylase, cellulase, invertase, alteration in carbon‐to‐nitrogen (C/N) ratio. Both bacterial fungal populations exhibited non‐concentration‐dependent response over time. this study, we refer 0.25%, 1.0% HT1, HT2, HT3, HT4, respectively. Initial MP application significantly reduced colony counts for while HT3 showed no change. On 60th day, HT1 higher count compared control. other hand, increased maximum day 1 but displayed distinct time‐dependent trend from days 15 60. Furthermore, enzyme decreased with increasing MPs an extended period. Molecular docking studies suggest that can hinder activity by forming hydrogen bonds enzymes. The C/N ratio found be MP‐treated soils relative control, suggesting relatively slower degradation carbon compounds soils.

Microplastics or micro-bioplastics released by wrinkling paper cup

The Science of The Total Environment, Journal Year: 2024, Volume and Issue: 945, P. 174123 - 174123

Published: June 20, 2024

Paper cups have been widely used such as in the fast-food industry for drinking and are generally made of disposable material. To make paper cup waterproof prevent leakage, a thin layer plastic polylactic acid (PLA) is commonly coated onto inner wall surface. This can potentially release debris microplastics, particularly when wrinkled/crumpled to break peel off coating layer, which tested herein. Using scanning electron microscope (SEM), broken be clearly observed. We then identify material using mass Raman spectra. further employ imaging released fallen down microplastics. cross-check image with SEM benefit each other increase analysis certainty, because via hyper spectrum signal-to-noise ratio, while visualise high resolution micro-/nano- size. particle algorithm estimate amount, at approximate 180 microplastic/wrinkle, or micro-bioplastic if considering main PLA bioplastic. Overall, we should not wrinkle avoid potential microplastics micro-bioplastics before during process, characterisation this report might helpful research on

Lactate exacerbates lung damage induced by nanomicroplastic through the gut microbiota–HIF1a/PTBP1 pathway

Experimental & Molecular Medicine, Journal Year: 2023, Volume and Issue: 55(12), P. 2596 - 2607

Published: Dec. 1, 2023

Abstract Exposure to nanomicroplastics (nano-MPs) can induce lung damage. The gut microbiota is a critical modulator of the gut–lung axis. However, mechanisms underlying these interactions have not been elucidated. This study explored role lactate, key metabolite microbiota, in development damage induced by nano-MPs (LDMP). After 28 days exposure (50–100 nm), mice mainly exhibited lungs and intestinal mucosa dysbiosis microbiota. Lactate accumulation was observed lungs, intestines serum strongly associated with imbalance lactic acid bacteria gut. Furthermore, no lactate germ-free mice, while depletion using cocktail antibiotics produced similar results, suggesting that may due changes components. Mechanistically, elevated triggers activation HIF1a/PTBP1 pathway, exacerbating nano-MP-induced through modulation epithelial–mesenchymal transition (EMT). Conversely, conditional knockout Ptbp1 ( flfl ) PTBP1 -knockout -KO) human bronchial epithelial (HBE) cells showed reversal effects signaling pathway. These findings indicate potential target for preventing treating LDMP.
