|発明の名称||IN-SOIL HARMFUL ELEMENT ORIGIN DISCRIMINATION METHOD|
PROBLEM TO BE SOLVED: To provide an in-soil harmful element origin discrimination method for discriminating whether harmful elements such heavy metals in soil are originated from nature or human, and a method for discriminating whether, on the basis of the origin determination, the soil containing harmful elements is natural origin contaminated soil or human origin contaminated soil.
SOLUTION: The in-soil harmful element origin discrimination method discriminates whether harmful elements contained in soil are originated from nature or human, and uses an EF value acquired from a ratio of concentration of a first element and a second element in oxidation phase/a ratio of concentration of the first element and the second element in reduction phase in the same soil, as origin discrimination index of harmful elements contained in the soil.
