Microplastics (MPs) and per- polyfluoroalkyl substances (PFASs) are ubiquitous contaminants in environments, yet their co-occurrence interactions remain insufficiently understood. In this study, we confirmed the concurrent presence of MPs PFASs distinct distribution patterns a wastewater treatment plant (WWTP) through comprehensive sampling analysis effort. Significant correlations (p < 0.05) were observed between specific types PFASs, suggesting shared sources. Moreover, identified as carriers with PFAS concentration ranging 122 166 ng/g, predominantly consisting perfluorooctanoic acid (PFOA) perfluorobutanoic (PFBA). The laboratory verification experiment revealed that could be leached from aqueous which commercial exhibited higher leaching potential, highest combined perfluorooctanesulfonate (PFOS), PFOA, PFBA reaching 10.4 ng/mL. PFOS demonstrated desorption efficiency exceeding 120% sorption/desorption experiments, confirming its release themselves. These results highlighted dual roles both sources PFASs. contaminant profiles across different matrices WWTP provide valuable insights form basis for further research into proactive measures to effectively mitigate environmental contamination.

The widespread presence of plastic debris in marine ecosystems was first highlighted as a serious concern the United Nations Convention on Law Sea (UNCLOS) and 1972 London Convention. This realization identified pollution one major global environmental issues. Majorities are neither recycled nor incinerated, result, it eventually makes its way into lakes, rivers, oceans. Analysis water sediment worldwide indicates that microplastics nanoplastic ubiquitous soils, freshwater, ecosystems. Microplastic nanoplastics distributed throughout environments via processes such biofouling chemical leaching, contaminating both pelagic benthic species. Despite growing recognition hazards posed by nanoplastics, regulatory efforts remain hampered limited understanding their broader ecological impacts, particularly how diverse factors translate population declines ecosystem disruptions. review examines pathways microplastic pollution, interactions with other stressors climate change effects food webs. highlights urgent need for further research behavior fate which degradation product microplastics, owing to nano size they pose additional risks, unique properties, potential impacts. Studies have demonstrated smaller more toxic than larger microplastics. Additionally, serve vectors contaminants heavy metals, exacerbating toxicity. They also translocate through chains, posing health risks. While evidence impact continues grow, chronic toxicity remains poorly understood, emphasizing research, at cellular level, fully understand human health. concludes call standardized measurement methods, effective mitigation strategies, enhanced international cooperation combat this escalating threat.

Synergistic toxicity of nanoplastics and Helicobacter pylori on digestive system in mice

Ecotoxicology and Environmental Safety, Год журнала: 2025, Номер 290, С. 117757 - 117757

Опубликована: Янв. 1, 2025

Nanoplastics, in combination with pathogenic microorganisms or toxic substances, have been shown to induce oxidative stress and disrupt energy lipid metabolism, posing significant health risks. This study evaluated the effects of co-exposure nanoplastics Helicobacter pylori on digestive system mice. Transmission electron microscopy confirmed accumulation AuPS-NPs (Au-core polystyrene nanoplastics) stomach, colon, liver, while hematoxylin eosin staining revealed dose-dependent pathological damage these tissues. Enzyme-linked immunosorbent assays quantified interleukin-6 (IL-6), malondialdehyde (MDA), triglyceride (TG), lactate dehydrogenase (LDH) levels, which significantly increased groups compared single-exposure (P < 0.05). After 28 days, 100 mg/L H. pylori-AuPS-NPs group showed highest levels IL-6 (172.91 ± 1.51 pg/mL 188.31 1.49 174.85 0.26 liver) MDA (13.49 0.16 nmol/mg 14.39 0.20 15.61 0.63 liver). These increases, accompanied by elevated TG LDH suggest aggravated inflammation, stress, metabolic disruption. Accumulation analysis that content over time higher concentrations, reduced nanoparticle gastric intestinal results indicate exacerbates tissue damage, disruptions modulating accumulation. findings highlight synergistic pylori, underscoring importance understanding combined exposure risks for public health.
