<p>A method of easily and rapidly cleaning a soil contaminated with organic contaminants such as hydrocarbon compounds and organohalogen compounds while preventing the abnormal proliferation of microorganisms preferably feeding on low-molecular nitrogenous substances and the generation of an offensive odor; and a cleaning material for use in the method. The cleaning method comprises adding to a soil contaminated with organic contaminants at least one material for cleaning selected between (a) a material for cleaning comprising wheat bran and/or tail flour and (b) a material for cleaning comprising wheat bran and/or tail flour and a microorganism material comprising an aerobic microorganism, or comprises adding to the soil a combination of either of the materials for cleaning and at least one compound selected among acetic acid, lactic acid, and methanol. The cleaning material is a material for cleaning comprising wheat bran and/or tail flour, a material for cleaning comprising wheat bran and/or tail flour and a microorganism material comprising an aerobic microorganism, or a cleaning material comprising either of the materials for cleaning and incorporated therein at least one compound selected among acetic acid, lactic acid, and methanol.</p> |
