Microplastics are a prolific environmental contaminant that have been evidenced in human tissues. Human uptake of microplastic occurs via inhalation airborne fibres and ingestion microplastic-contaminated foods beverages. Plastic PTFE-coated cookware food contact materials may release micro- nanoplastics into during preparation. In this study, the extent to which non-plastic, new plastic old releases microplastics prepared is investigated. Jelly used as simulant, undergoing series processing steps including heating, cooling, mixing, slicing storage replicate preparation undertaken home kitchens. Using non-plastic did not introduce simulant. Conversely, using resulted significant increases contamination. comprised PTFE, polyethylene polypropylene particulates fibrous particles, ranging 13-318 μm. Assuming meal was daily per prescribed methodology, be contributing 2409-4964 annum homecooked food. The health implications ingesting remains unclear.

Growing attention is being directed towards exploring the potential harmful effects of microplastic (MP) particles on human health. Previous reports exposure to MPs have primarily focused inhalation, ingestion, transdermal routes, and, potentially, transplacental transfer. The intravenous transfer MP in routine healthcare settings has received limited exploration existing literature. Standard hospital IV system set up with 0.9 % NaCl a laminar flow hood contamination precautions. Various volumes passed through system, some volumetric pump. Fluid filtered Anodisc filters washed isopropyl alcohol. cannula was immersed Mili-Q water for 72 h simulate vein conditions. Subsequently, and washed. Optical photothermal infrared (O-PTIR) microspectroscopy used examine particles. All examined from infusion contained particles, including polymer materials manufacture delivery systems (polydimethylsiloxane, polypropylene, polystyrene, polyvinyl chloride) arising plastic resin additives (epoxy resin, polyamide polysiloxane-containing MPs). geometric mean extrapolated result data indicated that approximately 0.90 per ml solution can be administered conventional absence However, implementation pump, this value may increase 1.57 ml. Notably, over h, single found release 558 polydimethylsiloxane, MPs, epoxy resin. Routine microplastics. are also released around cannulas, suggesting into circulatory during standard procedures.

Nano-Iron Oxide (Fe₃O₄) Mitigates the Effects of Microplastics on a Ryegrass Soil–Microbe–Plant System

ACS Nano, Год журнала: 2023, Номер 17(24), С. 24867 - 24882

To understand microplastic–nanomaterial interactions in agricultural systems, a randomized block 90-day pot experiment was set up to cultivate ryegrass seedings typical red sandy soil amended with compost (1:9 ratio). Polyvinyl chloride (PVC) and polyethylene (PE) microplastic (MP) contaminants were added into soils at 0.1 10%, whereas nano-Fe3O4 (as nanoenabled agrochemicals) 0.1% 0.5% comparison chemical-free controls. The combination of MPs significantly increased the pH (+3% + 17%) but decreased total nitrogen content (−9% – 30%; P < 0.05). treatment group both PE had highest C (29 g kg–1 vs 20 control) C/N ratio (13 8 control). Increased rhizosphere concentrations promoted growth (+42% dry weight) by enhancing chlorophyll (+20%) carotenoid (+15%) activities. Plant leaf root peroxidase enzyme activity more affected PVC than (+6%). Nano-Fe3O4 changed bacterial community structure from belowground (the rhizoplane endosphere) aboveground phylloplane). Under MP contamination, addition diversity (+0.35%) abundance (+30%) phylloplane further intensified connectivity networks (positive association 17%). structural equation model showed that change plant microbiome associated microbiome. Overall, these findings imply positive influences on soil–microbe–plant system establish method alleviate harmful effects accumulation soils.

Understanding the pathways of human exposure to micro(nano)plastics (MNPs) is crucial for assessing their health impacts. Intravenous infusion can induce MNPs direct entry into blood, posing serious risks on health, but remains unclear. Herein, we developed comprehensive analytical methods detect polyvinyl chloride (PVC) down 20 nm, and found about 0.52 μg equal 105-1011 particles PVC-MNPs released from intravenous products (IVIPs) during each 250 mL injection. The amounts IVIPs were dependent plastic materials, injection volume composition. These findings indicated that should be directly introduced blood circulatory system, causing impacts health. Our study reveals a previously ignored important pathway MNPs, calls further research potential these

Fish gills are highly sensitive organs for microplastic (MP) and nanoplastic (NP) invasions, but the cellular heterogeneity of fish to MPs NPs remains largely unknown. We employed single-cell RNA sequencing investigate responses individual cell populations in tilapia Oreochromis niloticus MP NP exposure at an environmentally relevant concentration. Based on detected differentially expressed gene (DEG) numbers, most affected immune cells by were macrophages, while stimulus primarily targeted T cells. In response NPs, H+-ATPase-rich exhibited distinct changes as compared with Na+/K+-ATPase-rich pavement Fibroblasts identified a potential cell-type biomarker interaction O. gills, evidenced reduced counts mostly DEGs among 12 populations. The MP-sensitive fibroblast subpopulation was lipofibroblasts. Cell–cell communications between fibroblasts cells, neurons, neuroepithelial significantly inhibited exposure. Collectively, our study demonstrated provided markers their toxicological mechanisms resolution.
