SOIL DECONTAMINATING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a soil decontaminating method by which the soil contaminated with heavy metals can be decontaminated efficiently and safely against the peripheral environment by using a specific additive when the heavy metals are absorbed into a plant grown in the contaminated soil to decontaminate the soil. SOLUTION: L-glutamic acid-di-acetic acid is made to coexist with the heavy metals in the contaminated soil when the heavy metals in the soil are absorbed into the plant and accumulated in the body of the plant to decontaminate the soil.
