The extensive utilization of nano-zero-valent iron (nZVI) and its engineered derivatives has prompted significant environmental concerns, particularly regarding their phytotoxicological impacts, which remain inadequately characterized. This investigation systematically evaluated the responses induced by nZVI, Chlorella vulgaris biochar (BC), loaded with (BC/nZVI) on mung bean seed germination subsequent seedling development. experimental data revealed that both nZVI BC/nZVI treatments significantly suppressed indices, including rate, radicle plumule elongation, biomass accumulation, demonstrating most pronounced inhibitory effects. During vegetative growth phases, exposure substantially impaired plant morphogenesis, manifested through reduced vertical growth, diminished fresh dry production, onset premature foliar chlorosis, necrosis, desiccation, and, ultimately, mortality. A comparative analysis indicated composites exhibited less severe photosynthetic inhibition relative to pristine nZVI. Biochemical assays demonstrated elicited substantial upregulation in antioxidant enzyme activities, superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), concomitant abnormal ferric ion accumulation root tissues. Notably, partial mitigation these physiological disturbances. These empirical findings underscore excessive bioavailability from induces stress, while BC matrix incorporation provides amelioration adverse effects ontogeny.
