The pervasive presence of microplastics (MPs) in agroecosystems poses a significant threat to soil health and plant growth. This study investigates the effects varying concentrations sizes polystyrene (PS-MPs) on Solanum lycopersicum L.'s height, dry weight, antioxidant enzyme activities, physicochemical properties, rhizosphere microbial communities. results showed that PS0510 treatment significantly increased height (93.70 cm, +40.83%) weight (2.98 g, +100%). Additionally, activities improved across treatments for S. L. roots. Physicochemical analyses revealed enhanced organic matter nutrient levels, including ammonium nitrogen, phosphorus, effective potassium. Using 16S rRNA sequencing molecular ecological network techniques, we found PS-MPs altered structure function community associated with PS1005 notably diversity displayed most complex network, while PS1010 led reduced complexity more negative interactions. Linear discriminant analysis effect size (LEfSe) identified biomarkers at various taxonomic reflecting impact structure. Mantel tests indicated positive correlations between activity, as well relationships properties activity. Predictions gene PS-MP modified carbon nitrogen cycling pathways, enhancing methanogenesis genes (mcrABG) negatively affecting denitrification (nirK, nirS). provides evidence agroecosystem functioning, highlighting their potential alter communities, thereby

Toxicity enhancement of microplastics released from food containers through thermal aging: Absorbing more serum proteins thus activating the innate immune response via actin polymerization

Environment International, Год журнала: 2025, Номер 197, С. 109358 - 109358

This study examined the effects of hot high-fat simulants on physicochemical properties microplastics (MPs) from polypropylene (PP)-, low-density polyethylene (LDPE)-, and polylactic acid (PLA)-based single-use food container (SUFC) leachates those aging their immunomodulatory effectors. Scenario studies have demonstrated that MPs were released these three types SUFCs. LDPE- PLA-based SUFCs also cellulose. Among SUFCs, only PP particles exhibited a new absorption peak at 1725 cm-1, which phenomenon may be attributed to presence unstable tertiary carbon atoms. Subsequently, we investigated removing additive both thermal-aged with polystyrene (PS) carboxyl-modified PS (PS-COOH) polymer backbones as reference materials. The findings indicated PS-COOH induced comparable innate immune responses, exhibiting similar size SUFC percolates. Consequently, selected original MPs, respectively, evaluate immunity. results revealed thata protein corona formed particle types, more adsorption observed particles. complex enhanced phagocytosis RAW264.7 macrophages increased expression pro-inflammatory genes NOS2 TNF-α through an actin polymerization cross-linking mechanism. In this study, how affect responses using model system, emphasizing importance comprehensive safety evaluations MPs.

Micro/Nanoplastics in plantation agricultural products: behavior process, phytotoxicity under biotic and abiotic stresses, and controlling strategies

Journal of Nanobiotechnology, Год журнала: 2025, Номер 23(1)

Опубликована: Март 21, 2025

With the extensive utilization of plastic products, microplastics/nanoplastics (MPs/NPs) contamination not only poses a global hazard to environment, but also induces new threat growth development and nutritional quality plantation agricultural products. This study thoroughly examines behavior MPs/NPs, including their sources, entry routes into plants, phytotoxicity under various biotic abiotic stresses (e.g., salinity, polycyclic aromatic hydrocarbons, heavy metals, antibiotics, plasticizers, nano oxide, naturally occurring organic macromolecular compounds, invasive Botrytis cinerea mycorrhizal fungi.) controlling strategies. MPs/NPs in systems mainly originate from mulch, sewage, compost fertilizer, municipal solid waste, pesticide packaging materials, etc. They enter plants through endocytosis, apoplast pathways, crack-entry modes, leaf stomata, affecting phenotypic, metabolic, enzymatic, genetic processes such as seed germination, metabolism, photosynthesis, oxidative stress antioxidant defenses, fruit yield nutrient quality, cytotoxicity genotoxicity. can interact with other environmental stressors, resulting synergistic, antagonistic, or neutral effects on phytotoxicity. To address these challenges, this review highlights strategies mitigate toxicity, novel green biodegradable plastics, plant extraction immobilization, exogenous regulator interventions, porous nanomaterial modulation, biocatalysis enzymatic degradation. Finally, identifies current limitations future research directions critical field.
