Nineteen specimens of earthquake-disaster waste taken from Ishinomaki, Shiogama and Kamaishi were analysed. The heavy metal contents and magnetic parameters (SIRM : saturated isothermal remanent magnetization andχ : magnetic susceptibility) of wood chip specimens processed from the specimens were measured. All of the obtained concentration values met the European Standard EN 14961-2. Characteristics of contamination and magnetic data was significantly different in each city. Specimens in Kamaishi had extremely large values of the concentration of Fe and magnetic data compared to those in other two cities. A simple correlation analysis revealed high correlations between magnetic parameters and some metals in Ishinomaki and Kamaishi specimens. It was shown that a simple inspection of heavy metal contamination in the woody waste in the two cities may be performed by measuring its SIRM or magnetic susceptibility.
