摘要
PROBLEM TO BE SOLVED: To provide a method for achieving a standard elution value 11 at which at least a contaminated soil can be disposed of at a controlled disposal site by insolubilizing heavy metals in a soil contaminated with at least one kind or plural kinds of heavy metals of hexavalent chromium, arsenic, selenium, cadmium, total mercury and lead whose elution characteristics are individually different from each other to inhibit the elution of the heavy metals. SOLUTION: A heavy metal elution inhibitor is the one, which inhibits the elution of heavy metals in the soil contaminated with at least one kind or plural kinds of heavy metals of hexavalent chromium, arsenic, selenium, cadmium, total mercury and lead and is the heavy metal elution inhibitor of the heavy metal contaminated soil which comprises alkali materials (L) containing fine powder of a blast furnace slag (S), gypsum (G) and calcium.
