ABSTRACT:
The invention provides a remediation method of soil, water and/or gases by prompt dehalogenation of halogenated hydrocarbons by allowing the halogenated hydrocarbons contained at least in one of the soil, water and/or gases to contact an iron powder containing about 0.03 to about 2% by mass of sulfur preferably on the surface, and an iron powder for use in the remediation method.
