AbstractAn outdoor pot experiment was conducted to study the control effects of zero-valent iron (Fe0) on arsenic (As) uptake by rice (Oryza sativa L.) and its relationship with iron (Fe), As, and phosphorus (P) in soil and Fe plaque. The results showed that Fe0 reduced total and inorganic As in root, husk, and grain but had no significant effect in straw, and almost all contents of As species in rice plant were decreased by Fe0. Total As contents in root, husk, and grain were decreased (54.8%, 39.9%, 30.1%), while reductions of inorganic As were 59.2%, 30.8%, and 30.3%, respectively. The inor...
