The elution behavior and control of hazardous trace elements from coal ash which was produced from the coal fired power plant were investigated. When the leaching test was carried out for seven coal ashes, the elution of As and Hg was not observed. However, the concentrations of B and Se in the leachate frequently exceeded the environmental quality standards for soil pollution in Japan. Also, the elution control of hazardous trace elements was examined. The elution of B and Se from coal ash was effectively inhibited by an acid washing using 0.1M HCl.
