Ecological and Health Risk Mediated by Micro(nano)plastics Aging Process: Perspectives and Challenges

Environmental Science & Technology, Год журнала: 2025, Номер unknown

Опубликована: Март 19, 2025

Aged micro(nano)plastics (MNPs) are normally the ultimate state of plastics in environment after aging. The changes physical and chemical characteristics aged MNPs significantly influence their environmental behavior by releasing additives, forming byproducts, adsorbing contaminants. However, a systematic review is lacking on effects ecological human health regarding increasing but scattered studies results. This Review first summarizes unique methods for quantifying aging degree. Then we focused potential impacts organisms, ecosystems, health, including "Trojan horse" under real conditions. Through combining meta-analysis analytic hierarchy process (AHP) model, demonstrated that, compared to virgin MNPs, would result biomass decrease oxidative stress increase organisms lead total N/P greenhouse gas emissions ecosystems while causing cell apoptosis, antioxidant system reaction, inflammation health. Within framework risk assessment, used quotient (RQ) physiologically based pharmacokinetic (PBK) models as examples illustrate importance considering degree data acquisition, model building, formula evaluation. Given risks our urgent call more understand hazards real-world environments.

Enhanced bioaccumulation and toxicity of Fenpropathrin by polystyrene nano(micro)plastics in the model insect, silkworm (Bombyx mori)

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

Опубликована: Янв. 23, 2025

Nano(micro)plastics (NMPs) and agrochemicals are ubiquitous pollutants. The small size physicochemical properties of NMPs make them potential carriers for pollutants, affecting their bioavailability impact on living organisms. However, little is known about interactions in terrestrial ecosystems. This study investigates the adsorption Fenpropathrin (FPP) onto two different sizes polystyrene examines impacts an insect model, silkworm Bombyx mori. We analyzed systemic effects acute exposure to FPP, individually combined, at organismal, tissue, cellular, gut microbiome levels. Our results showed that can adsorb with smaller particles having higher capacity, leading size-dependent increases bioaccumulation toxicity FPP. These led mortality, reduced body weight, delayed development, decreased cocoon production silkworms. Additionally, pollutants caused physical oxidative damage midgut altered gene expression related juvenile hormone (JH) silk protein synthesis. analysis revealed significant changes abundance potentially beneficial bacteria. Thus, aggravated induced by was size-dependent, (NPs) a greater impact. demonstrates role as contaminants, increasing findings have implications ecosystem health biodiversity.

Specific soil factors drive the differed stochastic assembly of rhizosphere and root endosphere fungal communities in pear trees across different habitats

Introduction Pyrus betulifolia is tolerant to diverse environmental conditions and commonly planted in infertile habitats (such as beaches ridges) conserve arable land for cereal crops. Symbiotic fungi the rhizosphere root endosphere benefit host plants by enhancing their resilience nutritional deficiencies under stressful conditions. However, mechanisms underlying assembly of these symbiotic fungal communities roots P. across different remain poorly understood. Methods 30-year-old were selected from five sites northern China investigate endosphere. Soil samples collected assess heterogeneity environment surrounding each plant. Procrustes analysis, variance partitioning ordination regression analysis employed explore ecological relationships between soil factors community composition. Results The exhibited higher richness, greater diversity lower structural variability compared Additionally, supported a network with abundance stronger connectivity than composition varies significantly among regions. In both communities, number genera specific mountainous regions was larger those plain areas saline-alkali areas. Null model-based analyses indicated that mainly governed stochastic processes. Specifically, non-saline-alkali soils, primarily driven dispersal limitation, whereas dominated drift. influenced Conclusion root-associated not only physicochemical properties but also compartment niche topography. Moreover, impact intensity alkaline nitrogen (AN) phosphatase (ALP), while more strongly affected pH sucrase (SUC). These findings could provide valuable insights design beneficial microbiomes enhance fruit tree performance.
