Abstract

The Codex Alimentarius Commission has decided a Maximum Level for inorganic As in polished rice in 2014 to protect consumers’ health risk. Flooding cultivation increases As concentration in rice grains, whereas aerobic treatment increases the concentration of Cd. Our strategy is a combination of flooded cultivation to decrease Cd and the application of iron materials to decrease As. Applications of materials lowered the As concentration in rice grain under flooded conditions. Using nontransgenic rice mutants which had nearly non-detectable levels of Cd in the grains, we have been testing the hypothesis that growing the low Cd cultivar aerobically simultaneously reduce As and Cd.
