Evaluation of Fenton, Photo-Fenton and Fenton-like Processes in Degradation of PE, PP, and PVC Microplastics

Water, Journal Year: 2024, Volume and Issue: 16(5), P. 673 - 673

Published: Feb. 25, 2024

The global problem of microplastics in the environment is “inspiring” scientists to find environmentally friendly and economically viable methods remove these pollutants from environment. Advanced oxidation processes are among most promising methods. In this work, potential Fenton, photo-Fenton, Fenton-like for degradation low-density polyethylene (LDPE), polypropylene (PP), poly(vinyl chloride) (PVC) water suspensions was investigated. influence three parameters on efficiency process tested: pH medium (3–7), mass added iron (10–50 times less than microplastics), H2O2 (5–25 more iron). effectiveness treatment monitored by FTIR-ATR spectroscopy. After 60-min treatments, PP microparticles were found be insensitive. Fenton PVC photo-Fenton LDPE PVC, changes FTIR spectra related observed. cases, optimized. It that a low (3) high (optimal values 1/12 1/10 respectively) favored all three. concentrations (25 higher iron), while significantly lower (11 15 treatment, respectively), suggesting scavenging activity occurs.

Polystyrene Nano- and Microplastic Particles Induce an Inflammatory Gene Expression Profile in Rat Neural Stem Cell-Derived Astrocytes In Vitro

Nanomaterials, Journal Year: 2024, Volume and Issue: 14(5), P. 429 - 429

Published: Feb. 27, 2024

Microplastics are considered an emerging environmental pollutant due to their ubiquitous presence in the environment. However, potential impact of microplastics on human health warrants further research. Recent studies have reported neurobehavioral and neurotoxic effects marine rodent models; however, underlying cellular physiology mammals remains unclear. Herein, we exposed neural stem cells cell-derived astrocytes, oligodendrocytes, neurons various sizes concentrations polystyrene nano- microplastics. We investigated uptake, cytotoxicity, alteration gene expression through transcriptome profiling. The cell type most affected by decreased viability were astrocytes after 7 days repeated exposure. Transcriptional analysis showed that 1274 genes differentially expressed 500 nm microplastics, but only 531 altered 50 nanoplastics. Both canonical pathway Kyoto Encyclopedia Genes Genomes upregulated pathways involved neuroinflammation, innate adaptive immunity, migration, proliferation, extracellular matrix remodeling, cytoskeleton structures. downregulated lipid metabolism, specifically fatty acid oxidation cholesterol metabolism. Our results show repeatedly for undergo changes hallmarks astrogliosis.

The gut microbiota, a key to understanding the health implications of micro(nano)plastics and their biodegradation

Microbial Biotechnology, Journal Year: 2022, Volume and Issue: 16(1), P. 34 - 53

Published: Nov. 22, 2022

Abstract The effects of plastic debris on the environment and plant, animal, human health are a global challenge, with micro(nano)plastics (MNPs) being main focus. MNPs found so often in food chain that they provoking an increase intake. They have been detected most categories consumed foods, drinking water, even feces. Therefore, oral ingestion becomes source exposure to MNPs, gastrointestinal tract, primarily gut, constantly interacts these small particles. consequences remain unclear. However, current vivo studies vitro tract models shown several types sizes impact gut intestinal bacteria, affecting homeostasis. typical microbiome signature MNP is associated dysbiosis loss resilience, leads frequent pathogen outbreaks, local systemic metabolic disorders. Moreover, micro‐ nano‐plastic particles animal tissues accumulated evidence microbial degradation plastics/MNPs by bacteria insect microbiota raise issue whether make key contributions bio‐transformation ingested MNPs. Here, we discuss issues unveil complex interplay between microbiome. elucidation biological this interaction both host undoubtedly challenging. It expected biotechnology research could help decipher extent which microorganisms diversify MNP‐determinant species, mechanisms, enzymatic systems, as well become important understand our response provide background information inspire future holistic studies.

The accumulation of microplastics (MPs) in the environment as well their presence foods and humans highlight urgent need for studies on effects these particles humans. Polylactic acid (PLA) is most widely used bioplastic food industry medical field. Despite its biodegradability, biocompatibility, "Generally Recognized As Safe" (GRAS) status, recent animal model have shown that PLA MPs can alter intestinal microbiota; however, to date, no been reported possible gut health consequences intake by This work simulates ingestion a realistic daily amount pass through gastrointestinal tract combining INFOGEST method simgi® evaluate human colonic microbiota composition (16S rRNA gene sequencing analysis) metabolic functionality (lactic short-chain fatty acids (SCFA) production). Although did not clearly microbial community homeostasis, increased Bifidobacterium levels tended increase millimetric particles. Furthermore, shifts detected at functional level suggest an alteration metabolism, biotransformation community.
