The effect of fresh and aged nZVI on Cd uptake and translocation by Noccaea plant in two contrasting soils from industrial areas (Spain and the Czech Republic)

Original language description

A promising approach for managing cadmium (Cd) contamination in soils is the combined use of chemical stabilization using nano zero-valent iron (nZVI) and phytoextraction with hyperaccumulator plants, which also serve as bioindicators to assess immobilization effectiveness. This study addresses a critical knowledge gap in understanding how nZVI amendments influence Cd uptake and isotope fractionation in hyperaccumulator plants across contrasting industrial soils. By integrating Cd stable isotope tracing with soil-specific treatments of fresh and aged nZVI, we elucidate the mechanistic interplay between chemical stabilization, soil properties, and plant-driven processes, enabling tailored remediation strategies. These insights advance nano-enabled phytoremediation beyond traditional approaches by linking nanoparticle aging and soil organic matter interactions to Cd bioavailability and translocation. We show that nZVI's modulation of Cd bioavailability and isotope signatures varies with soil properties and particle aging. In alkaline arenosol (low organic matter), aged nZVI reduced Cd bioavailability by 68 % through Fe-oxide formation, adsorbing lighter isotopes (Delta 114/110Cdpore water-soil = +0.352 %o) and reducing root uptake. In acidic, high-organic fluvisol, Noccaea caerulescens reduced Cd in pore water by 25 times but maintained consistent root-soil fractionation (Delta 114/110Cdroot-soil approximate to -0.29 to -0.406 %). Roots accumulated lighter, shoots heavier isotopes (Delta 114/110Cdshoot-root up to +0.372 %), suggesting vacuolar sequestration and selective xylem transport. Despite lower Cd uptake in nZVI-treated arenosol, translocation factors increased in fluvisol, indicating enhanced shoot Cd allocation. Overall, the study highlights the synergy of chemical stabilization and phytoextraction, emphasizing soil-specific strategies integrating nanoparticle aging and organic-inorganic interactions.
