With the increase in traffic due to urbanization, tire wear particles (TWPs) derived compounds persistently accumulate soil environment. This study addresses critical knowledge gaps regarding ecotoxicological effects of TWP-derived contaminants, N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD) and its precursor, 6PPD-quinone (6PPD-Q), on soil-dwelling organisms. The findings demonstrated that 6PPD-Q accumulated at a higher concentration (6.77 ± 0.124 ng/g) earthworms (Eisenia fetida) compared 6PPD (5.41 0.002 ng/g), triggering more severe oxidative stress cellular homeostatic imbalance. Specifically, 100 ng/g significantly elevated reactive oxygen species (ROS) levels by 180.77% suppressed acetylcholinesterase (AchE) Ca2+-ATPase activities 17.14% 44.70%, respectively. Notably, uniquely disrupted nitrogen balance disturbed energy supply strongly inhibiting fatty acid degradation peroxisome proliferator-activated receptor (PPAR) signaling pathways. Additionally, profoundly altered abundance key microbes microbial network stability, affecting intestinal functions such as bile secretion, hormone synthesis, lipid digestion, thus exacerbating metabolic imbalance earthworms. deciphers molecular toxicity mechanisms contaminants earthworms, providing crucial insights for developing risk assessment frameworks mitigation strategies ecosystems.
