Nanoenabled agriculture technology exhibits potential in reducing arsenic uptake rice; however, a systematic understanding of the rice-soil-microorganism process nanomaterials (NMs) is lacking. Soil amendment metalloid NMs, including SiO2, hydroxyapatite, S0, and Se0 at 10-100 (0.1-5.0 for Se NMs) mg/kg, increased rice biomass by 76.1-135.8% arsenic-contaminated soil (17.0 mg/kg) decreased accumulation plant tissues 9.3-78.2%. The beneficial effects were nanoscale-specific NMs type- concentration-dependent; 5 mg/kg showed greatest growth promotion decrease As accumulation. Mechanistically, (1) optimized bacterial community structure, enhancing abundance arsM 104.2% subsequently increasing methylation 276.1% rhizosphere compared to arsenic-alone treatments; (2) metabolomic analyses that upregulated biosynthesis pathway abscisic acid, jasmonic glutathione, with subsequent downregulation transporter-related gene expression roots 42.2-73.4%, decreasing formation iron plaque 87.6%, detoxification 50.0%. Additionally, significantly enhanced arsenic-treated yield 66.9-91.4% grain nutritional quality. This study demonstrates excellent an effective sustainable strategy increase food quality safety.
