PROBLEM TO BE SOLVED: To provide a metal powder for decomposing organic halogen compounds, which is capable of decomposing persistent organic halogen compounds contained as pollutants in soil, underground water and the like at a high speed. SOLUTION: As the metal powder for decomposing the organic halogen compounds capable of decomposing and cleaning at a high speed the persistent organic halogen compounds, such metal powder is prepared as a metal powder having an adhesion metal phase 2 in which metal particles 3 composing a metal powder 4 contain nickel as a main component and a base metal phase 1 in which iron is a main component, the metal powder 4 having an adhesion metal phase 2 containing manganese as a main component and a base metal phase 1 containing aluminum as a main component, or a metal powder composed of aluminum dross generated in an aluminum smelting process. The organic halogen compounds in an environment are decomposed and cleaned at a high speed using the methods of mixing any of the above metal powders with the soil polluted with the organic halogen compounds.
