Description:
Stack emissions of metals from stationary sources are of present interest to the United States Environmental Protection Agency (USEPA), to state and local governments, to industries, and to the public. hen regulations require limitation of metals stack emissions, it follows logically that measurement methodology is necessary for determining compliance to the established limits. his presentation presents a broad overview of measurement methodology for the purpose of determining multiple metals stack emissions of up to sixteen metals using one sampling train developed by the Atmospheric Research and Exposure Assessment Laboratory of USEPA. sokinetic sampling from a grid of points produces a representative sample from which the multiple emissions of up to sixteen metals can be measured in the sample from one train. etals in the stack particulate matter and in the gases are measured separately. he samples are prepared by digestion for subsequent instrumental analysis by inductively coupled plasma or atomic absorption spectroscopy. he sixteen metals are total Cr, Cd, As, Ni, Mn, Be, Cu, Zn, Pb, Se, P, T1, Ag, Sb, Ba, and Hg. mission factor development, research requiring quantification of metals emissions, and determining emission compliance are important potential applications of this methodology.
