Microbeads used in personal care products have been one of the important sources microplastics (MPs), and little has reported on their environmental behaviors health risks. The characteristics environmentally persistent free radicals (EPFRs) toxicity assessment MPs (environmentally relevant concentrations) from cosmetics during photoaging remains largely unknown. In this study, formation EPFRs polyethylene (PE) microbeads facial scrubs under light irradiation were investigated using C. elegans as a model organism. results suggested that induced generation EPFRs, which accelerates aging process alters physicochemical properties PE microbeads. Acute exposure to (1 mg/L) at photoaged times 45-60 d significantly decreased physiological indicators (e.g., head thrashes, body bends, brood size). oxidative stress response stress-related gene expression also enhanced nematodes. addition N-acetyl-l-cysteine significant inhibition nematodes exposed PE. Pearson correlation showed concentration was correlated with indicators, stress, related-genes data confirmed combined heavy metals organics contributed by PE, might be involved regulating adverse effects elegans. study provides new insight into potential risks released environment photoaging. findings highlight necessity for considering role evaluating impacts

Generation of environmentally persistent free radicals on photoaged tire wear particles and their neurotoxic effects on neurotransmission in Caenorhabditis elegans

Environment International, Journal Year: 2024, Volume and Issue: 186, P. 108640 - 108640

Published: April 1, 2024

Tire wear particles (TWP) are a prevalent form of microplastics (MPs) extensively distributed in the environment, raising concerns about their environmental behaviors and risks. However, knowledge regarding properties toxicity these at environmentally relevant concentrations, specifically role persistent free radicals (EPFRs) generated during TWP photoaging, remains limited. In this study, evolution EPFRs on under different photoaging times adverse effects Caenorhabditis elegans were systematically investigated. The process primarily resulted formation reactive oxygen species (O2•−, ⋅OH, 1O2), altering physicochemical TWP. exposure nematodes to 100 μg/L TWP-50 (TWP with time 50 d) led significant decrease locomotory (e.g., head thrashes, body bends, wavelength) neurotransmitter contents dopamine, glutamate, serotonin). Similarly, expression neurotransmission-related genes was reduced exposed TWP-50. Furthermore, addition free-radical inhibitors significantly suppressed TWP-induced neurotoxicity. Notably, correlation analysis revealed negative between levels nematodes. Thus, it concluded that photoaged induce neurotoxicity by affecting neurotransmission. These findings elucidate mechanisms EPFRs, emphasizing importance considering contributions when evaluating risks associated
