The environmental and health challenges posed by petroleum-based biodegradable plastics, such as polybutylene succinate (PBS) polybutyleneadipate-co-terephthalate (PBAT), are a significant concern because they increasingly present in the environment contribute substantial proportion of microplastics (MPs) or nanoplastics (NPs). In this study, ultraviolet (UV)-aged PBS-NPs PBAT-NPs found to have higher propensity accumulate within body Caenorhabditis elegans (C. elegans) prolonging defecation interval, which could induce severe neuronal damage compared pristine NPs. increased accumulation (BNPs) subsequent impairments neurobehavior highly attributed their reduced particle size altered surface properties, including changed chemical bonds functional groups after photoaging. Aged BNPs also cause more GABAergic neurons neurotransmitter receptors, resulting disrupted homeostasis behaviors. Overall, both PBS PBAT components show no differences biological mechanisms neural damage, highlighting commonalities characteristics adverse effects on nervous system. Our study opens up exploration impacts photoaging degradation state that environment.

Adsorption of Macrolide Antibiotics by Aged Microplastics of Different Sizes: Mechanisms and Effects

Nanomaterials, Год журнала: 2025, Номер 15(6), С. 467 - 467

Опубликована: Март 19, 2025

Microplastics (MPs) and antibiotics are widely detected in water bodies. However, the adsorption behavior mechanism of different particle size polystyrene (PS) MPs on macrolide under natural aging remain to be elucidated. In this study, potassium persulfate (K2S2O8) was used simulate process PS MPs. The (80 400 μm) toward azithromycin (AZI), clarithromycin (CLA), erythromycin (ERY) were investigated. Results SEM showed that surface roughness aged increased with appearance cracks, pits, pores. XPS FTIR analyses enhanced C=O functional groups process. isotherm models revealed processes AZI, CLA, ERY tendency, as evidenced by highest capacity for aged-80 μm (645, 665, 184 mg/kg) > original-80 (412, 420, 120 mg/kg), aged-400 (280, 330, 110 original-400 (197, 308, 100 mg/kg). Kinetic model fitting occurred three stages: rapid, slow, saturation. Adsorption kinetic curves original conformed pseudo-second-order model. contrast, data fit Langmuir model, indicating primarily involved uniform monolayer chemical adsorption. Our findings provide insights into substantial changes interactions between processes.

Enhanced the interaction of biodegradable microplastics with tetracycline by persulfate oxidation process

Environmental Technology, Год журнала: 2025, Номер unknown, С. 1 - 11

Опубликована: Май 22, 2025

The interaction of biodegradable microplastics with pollutants has raised widespread public attention recently. However, investigation on the under oxidation process is limited. In this study, polyhydroxyalkanoates (PHA-MPs) tetracycline (TC) persulfate-based systems was investigated. Characterization results indicated that persulfate not only changed surface morphology PHA-MPs, but also produced many oxygen-containing functional groups. Meanwhile, through application 2D-COS analysis, sequence groups in PHA-MPs clearly identified. adsorption capacity maximized at pH = 7, and high salinity inhibited capacity, while addition Co(II), Ni(II), Cu(II) could significantly promote capacity. addition, kinetics fitted well pseudo-second-order kinetic model, isothermal followed Freundlich which belonging to multi-layer adsorption. above were helpful further assess risks associated combined pollution MPs organic pollutants.
