Ferroferric oxide nanoparticles (Fe3O4 NPs) are widely utilized as nanoenabled agrochemicals and soil remediation agents, with functional modification significantly enhancing their stability biocompatibility. However, excessive use of Fe3O4 NPs may pose unassessed ecological risks in soils, particularly concerning the regulatory role two most common surface modifiers polyvinylpyrrolidone (PVP) citric acid (CA) which influence interactions organisms potential toxicity. This study evaluated nanotoxic effects bare (B-Fe3O4 NPs), CA-Fe3O4 NPs, PVP-Fe3O4 on Eisenia fetida ecosystems. After 7 days exposure, B-, CA- decreased weight earthworms, caused oxidative stress tissue damage. Functional showed increased accumulation earthworms while alleviating homeostatic imbalance by accelerating activation related enzymes. Moreover, hyperspectral pathological observations indicated that CA PVP modifications effectively alleviated damage via an improvement NP biocompatibility, dispersion evidenced levels inositol metabolites, has been upregulated more B-Fe3O4 NPs. Significant metabolic disturbances were observed, indicating forced to adjust amino metabolism consume energy detoxify repair work supplements toxic assessment provides crucial insights for optimizing safety through functionalization.
