| | Abstract | | Waste home appliances contain useful metal. However, prior to the enactment of the Basic Law for Establishing the Recycling-based Society in 2000, these wastes were dumped into landfills without preprocessing. Some of the rare metals are considered possible to move in the layer and form the metal-enriched zones due to the internal environment in the landfills. In order to identify the metal-enriched zones, it is necessary to visualize the condition in landfills. Therefore, we adopted electric prospecting as the visualization method, and examined its effectiveness by some experiments for the water reclamation waste site. In the field experiment, we measured the resistivity and the chargeability, and obtained the profiles. In the laboratory experiment, the resistivity, the percent frequency effect (PFE) and the chargeability were measured using each drilled sample. Also, we analyzed some metal concentrations with each core. |
