摘要：
A method and composition for the remediation of environmental contaminants in soil, sediment, aquifer material, water, or containers in which contaminants were contained, wherein contaminants are reacted with a remediating composition comprising a metal and a sulfur-containing compound to produce environmentally-acceptable, chemically reduced products. The method is useful for treating contaminants such as halogenated hydrocarbons, pesticides, chemical warfare agents and dyes. The remediating composition preferably contains comminuted, commercial grade iron and iron sulfide. The addition of an alcohol to the reactants enhances the rate of the remediation reaction, particularly for contaminants of soils and sediments.
