- Soil heterogeneity influences the biotoxicity of photoaged tire wear particles in Eisenia fetida: A comparative assessment. Zhou, Hanghai Wang, Xin Sun, Hong Li, Hua Wu, Zhou Li, Yongfu Yao, Xiaohong Zhou, Jianjiang Jiang, Lijia Wang, Yuan Jin, Junwei Zhang, Chunfang Tang, Jiangwu Oligochaeta Animals Soil Gastrointestinal Microbiome Soil Pollutants Oxidative Stress Reactive Oxygen Species Tire wear particles (TWPs) pose escalating environmental concerns owing to their aging-enhanced toxicity. However, the combined effects of photoaging and soil heterogeneity remain poorly understood. This study investigated the impact of virgin and photoaged TWPs on Eisenia fetida in three soil types (red, black, and loess), focusing on earthworm survival, weight loss, antioxidant responses, histopathological changes, and gut microbiota shifts. Results showed that photoaging significantly increased TWP toxicity, as evidenced by elevated surface environmentally persistent free radicals. High-dose exposure to photoaged TWPs caused the greatest reduction in earthworm survival (52.2 % vs. control, P
