| Research Abstract |
Arsenic concentration not only in drinking water but also in cooking water could affect the arsenic intake. We provided cooking water that contain low arsenic to local people, and found that arsenic intake via food, especially via rice, was decreased. In Bangladesh, they use water for polishing rice as well as for cooking. We found that arsenic in the water used for polishing rice also affected the arsenic content in the rice. Generally, arsenic-contaminated well water also contain iron and the iron could co-precipitate with arsenic. The application of this co-precipitation process can reduce the arsenic concentration in polishing water and thus in polished rice.
