<p><P>PROBLEM TO BE SOLVED: To solve the problems such as uncertainty in a microbial method, the poorness of work efficiency in a vacuum extraction method, the large quantity consumption in a method for mixing slaked lime and/or calcium aluminate with soil or the like, in a cleaning method for soil polluted with an organohalogen compound. <P>SOLUTION: The polluted soil cleaning agent for soil containing the organohalogen compound is characterized in that calcium aluminosilicate and water are contained. A method for injecting the polluted soil cleaning agent in the ground is disclosed. Since the organohalogen compound such as trichloroethylene, carbon tetrachloride, tetrachloroethylene, methylene chloride or the like can be effectively cleaned using this polluted soil cleaning agent, soil polluted over a wide range with a dry cleaning solvent and a degreasing agent of an electronic component and a metal product or the like can be efficiently cleaned. <P>COPYRIGHT: (C)2003,JPO</p> |
