Tire wear particles (TWPs) have caused increasing concerns due to their detrimental effects on the soil ecosystem. However, role of weathering in altering toxicity TWP organisms is poorly understood. In this study, original and photoaged was compared using earthworms (Eisenia fetida) as model organisms. The obtained results indicated that photoaging resulted an increase environmentally persistent free radicals (EPFRs) from 3.69 × 1017 5.20 spin/g. Meanwhile, induced changes toxic endpoint E. fetide, i.e., weight loss death ratio 0.0425 0.0756 g/worm 23.3 50% under a 10% concentration, respectively. Analyses transcriptomics, antioxidant enzyme activity, histopathology demonstrated enhanced mainly oxidative damage, which by disruption defense system. Free-radical quenching correlation analysis further suggested excessive production ex vivo reactive oxygen species, EPFRs, led exhaustion Overall, work provides new insights into potential hazard weathered environment has significant implications for recycling proper disposal spent tire particles.

Reactive oxygen species (ROS) are ubiquitous in the natural environment and play a pivotal role biogeochemical processes. However, spatiotemporal distribution production mechanisms of ROS riparian soil remain unknown. Herein, we performed uninterrupted monitoring to investigate variation at different sites Weihe River zone throughout year. Fluorescence imaging quantitative analysis clearly showed soils.

Photochemically generated reactive oxygen species (ROS) are widespread on the earth's surface under sunlight irradiation. However, nonphotochemical ROS generation in water (e.g., paddy overlying water) has been largely neglected. This work elucidated drivers of and its spatial distribution undisturbed water, by combining imaging technology with situ monitoring. It was found that H2O2 concentrations formed three waters could reach 0.03–16.9 μM, profiles exhibited heterogeneity. The O2 planar-optode indicated redox interfaces were not always at soil–water interface but also possibly layer, depending soil properties. facilitated a rapid turnover reducing oxidizing substances, creating an ideal environment for ROS. Additionally, electron-donating capacities increased 4.5–8.4 times compared to top layers. Importantly, field investigation results confirmed sustainable •OH through pathways constituted significant proportion total daily production (>50%), suggesting comparable or even greater role than photochemical generation. In summary, process reported this study greatly enhances understanding natural processes soils.
