Abstract

This study was performed to establish new methods for hazardous substances and to develop an analytical method in specified wastes for preventing the environmental pollution caused by hazardous wastes. Therefore, the trends of international management, regulatory criteria, and items of hazardous wastes in various countries were investigated. Based on this study, target priority of new hazardous substances in specified wastes was established. An analytical method was developed using the waste standard reference materials of sludge, oil, bottom ash, etc., which contain the new hazardous substances (Ba, Be, Cr(VI), F, Ni, Sb, Se, and V). A total of 37 waste samples from the representative facilities, which are emitting new hazardous substances, were analyzed.
