  • Arsenic is found naturally in some foods, including fish and shellfish, and in waters and soils.

    Inorganic arsenic is found in industrial materials and gets into water—including water used to submerge rice paddies.

    Rice is easily inundated with weeds and other crops, but it has one advantage: It grows well in water. So farmers germinate the seeds, and when the seedlings are ready, plant them in wet soil. They then flood their fields, which suppresses weeds, but allows the rice to flourish. Rice readily absorbs the water and everything in it—including arsenic, either naturally occurring or not. Most of the world’s rice is grown this way.

    “What happens in rice, because of complex biogeochemical processes in the soil, when temperatures and CO2 go up, inorganic arsenic also does,” Ziska said. “And it’s this inorganic arsenic that poses the greatest health risk.”

    If I’m understanding correctly, the risk is from flooding the fields with contaminated water

    A farm that relies on flooding the field with rain from a rainy season should be unaffected? Or minorly affected, right?
