Exhaust gas regulations for harmful components have been established in most countries of the world. In order to establish reduction technology for harmful components in exhaust gas, technology is required for the real-time detection of trace heavy metal components. In this paper, a method for the detection of trace heavy metal components using laser induced breakdown spectroscopy (LIBS) was examined with respect to powder and gas phase samnles. Detection characteristics were obtained for Pb and Cr in real ash, and measurement sensitivity under 500 mg/kg was confirmed, Detection characteristics were also obtained for As, Be, Cd, Co, Cr, Hg, Mn, Ni, Pb, Se, and Sb in gas, and measurement sensitivity under 0.1 mg/Nm^3 was confirmed for these elements, except for As and Se. Future use of high sensitivity techniques is expeded to reach a sensitivity level under 0.1 mg/Nm^3 for As and Se.
