摘要: The distribution of Cd, Co, Cu, Ni, Pb, Zn, Mn, and Fe in soils dedicated to rice crops have been studied. Total content extractable fraction determined by acid digestion extraction with EDTA, respectively. A method selective sequential (SSE) has applied determine the metals bound organic matter, soluble plus exchangeable, precipitated carbonates, associated Mn amorphous oxides, sulfides, residual; all elements show their most important as precipitates, mainly forms sulfides carbonates. available plants matter are less represented, except for Cu Ni.
