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.

The global threat of antimicrobial resistance (AMR) is exacerbated by the mobilization genes (ARGs) occurring in different environmental niches, including seawater. Marine environments serve as reservoirs for resistant bacteria and ARGs, further complicated ubiquity microplastics (MPs). MPs can adsorb pollutants promote bacterial biofilm formation, creating conditions favorable to dissemination ARGs. This study explores dynamics ARG transfer marine bivalve

New Horizons in Micro/Nanoplastic-Induced Oxidative Stress: Overlooked Free Radical Contributions and Microbial Metabolic Dysregulations in Anaerobic Digestion

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 5, 2024

Excessive production of reactive oxygen species (ROS) induced by micro/nanoplastics (MPs/NPs) is highly toxic to microbes. However, the mechanisms underlying ROS generation and metabolic regulation within anaerobic guilds remain poorly understood. In this study, we investigated effects environmentally relevant levels polypropylene (PP)-MPs/NPs on oxidative stress microbial ecology during digestion (AD). Electron paramagnetic resonance spectroscopy revealed that PP-MPs/NPs elevated concentrations persistent free radicals (EPFRs) derived hydroxyl (•OH). EPFRs were identified as primary contributors •OH generation, evidenced a high Spearman correlation coefficient (r = 0.884, p < 0.001) radical-quenching studies. The formation enhanced 86.2–100.9%, resulting in decreased cellular viability methane (by 37.5–50.5%) at 100 mg/g TS PP-MPs/NPs. Genome-centric metagenomic metatranscriptomic analyses suggested reassembly community structures, re-evolution functional traits, remodeling interspecies interactions. Specifically, shift methanogen consortia from hydrogenotrophic Methanofollis sp. acetoclastic Methanothrix soehngenii, primarily because latter's diverse ingestion patterns, electron bifurcation complexes, ROS-scavenging abilities. Downregulation genes associated with antioxidative defense systems (i.e., sodN, katA, osmC) ROS-driven redox signal transduction pathways (c-di-AMP phosphorylation signaling pathways) provided insights into ROS-induced dysregulation. Our findings enhance understanding ecological traits under MPs/NPs stressors, facilitating control toxicity stabilization AD processes.
