Abstract

Arsenic (As) uptake and distribution in the roots, shoots, and grain of wheat (Triticum durum) grown in 2 As polluted soils (192 and 304 mg kg -1 respectively), and an uncontaminated soil (14 mg kg-1 ), collected from Scarlino plain (Tuscany, Italy), was investigated with respect with phosphorus fertilization. Three different level of phosphorus (P) fertilization: PO [0 kg ha-1], Pl [75 kg ha-1], and P2 [150 kg ha-1], as KH2PO4 of P, were applied. The presence of high concentrations of As in soils reduced plants growth, decreased grain yield and increased root, shoot and grain As concentrations, especially in the absence of P fertilization. The P fertilization decreased the As concentration in all the tissues as well as the translocation of As to the shoot and grain. This observation may be useful in certain areas of the world with high levels of As in soils, to reduce the potential risk posed to human health by As entering the food-chain.
