Moreover, approximately 10% of rice Cd levels posed potential health hazards, with some samples presenting lifetime carcinogenic risks.

The derived reference values for dietary Cd were 0.149 and 0.018 micrograms per kilogram of body weight per day for adults and children, respectively. The lowest concentrations of Cd in rice consumed by adults and children were also observed, which indicated that current Cd limit standards appear insufficient to protect public health, indicating a
