Sampling and Analytical Methodologies for PCDDs and PCDFs in Incinerators and Wood Burning Facilities
Representative stack samples were taken from typical combustion sources and wood burning stoves using isokinetic sampling techniques. Each segment of the sampling trains and coincident collected flyash samples were analyzed for polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs). Analyses indicated that the bulk of the PCDDs/PCDFs were directly associated with particulate matter in the exhausted effluent and that woodstove effluents contained only components with high chlorine numbers. Samples were submitted to cytosol receptor bioassay and produced responses far higher than the expected values based on the 2,3,7,8-tetrachloro-dibenzo-p-dioxin (TCDD) concentrations measured. Results from solvent extraction and cleanup column recovery studies are reported. Data for PCDDs/PCDFs concentrations are reported and discussed.
