The Role of irrigation techiniques in Cd bioaccumulation in rice (Oryza sativa L.)

The bioaccumulation of toxic elements in rice is of great concern worldwide because rice is the staple food for billions of people. The uptake of toxic elements (like As, Cd and Pb) in rice comes mainly from their interaction with system soil/water, and the reducing conditions typical of paddy fields play often a decisive role in the mobilization of specific chemical forms of these elements.Our results demonstrate that sprinkling irrigation may be an alternative and promising method in order to produce rice containing low amounts of toxic elements in kernels.
