METHOD FOR DETERMINING PURIFICATION PROCESSING OF OIL CONTAMINATED SOIL

摘要

PROBLEM TO BE SOLVED: To provide a new determination method capable of accurately determining necessity of purification processing for oil contaminated soil and a purification target value independently of an oil type and an oil concentration.

SOLUTION: The determination method includes: a step (S10) for analyzing the oil concentration of soil contaminated with oil; a step (S20) for preparing a plurality of simulated contaminated soils; a step (S30) for growing plants by using the prepared simulated contaminated soils; a step (S40) for measuring a chlorophyll concentration of leaves of each grown plant; and a step (S50) for determining the necessity of purification processing of contaminated soil and its purification target value on the basis of relation between the chlorophyll concentration of each plant and the oil concentration of each simulated contaminated soil.
