Abstrakt: Foliar application of zinc (Zn) or silicon nanoparticles (Si-NPs) may exert regulatory effects on cadmium (Cd) accumulation in rice grains, however, their impact on Cd bioavailability during human rice consumption remains elusive. This study comprehensively investigated the application of Zn with or without Si-NPs in reducing Cd accumulation in rice grains as well to exactly evaluate the potential risk of Cd exposure resulting from the rice consumption by employing field experiment as well laboratory bioaccessibility and bioavailability assay. Sole Zn (ZnSO 4 ) or in combination with Si (ZnSO 4 +Si and ZnO+Si) efficiently lowered the Cd concentration in rice grains. However, the impact of bioaccessible (0.1215-0.1623 mg kg -1 ) and bioavailable Cd (0.0245-0.0393 mg kg -1 ) during simulated human rice consumption depicted inconsistent trend. The straw HCl-extractable fraction of Cd (F HCl-Cd ) exhibited a significant correlation with total, bioaccessible, and bioavailable Cd in grains, indicating the critical role of F HCl-Cd in Cd accumulation and translocation from grains to human. Additionally, foliar spraying of Zn+Si raised the nutritional value of rice grains, leading to increased protein content and reduced phytic acid concentration. Overall, this study demonstrates the potential of foliar application of ZnSO 4 +Si in mitigating the Cd levels in rice grains and associated health risks upon consumption.
