PROBLEM TO BE SOLVED: To provide a method for analyzing hazardous material content in soil, capable of obtaining measurement results which are quite similar as by the stripping method and of performing simple and quick analysis, in analyzing hazardous materials in the soil. SOLUTION: In this method for analyzing hazardous material content in the soil, the hazardous material content is analyzed by the fluorescent X-ray analysis method using the sampled soil as a sample for a front analysis process. In an elusion process, an aqueous solvent is added and mixed to the soil to elute hazardous materials from the soil used as the sample, and then liquid-solid separation is carried out. In a post-analysis process, the hazardous material content is analyzed by the fluorescence X-ray analysis method using a solid component after the liquid-solid separation as the sample. In an elusion quantity calculation process, the hazardous material content analyzed in the post-analysis process is subtracted from the hazardous material content analyzed by the front analysis process, and the content of the eluted hazardous material is calculated.
