The precision and accuracy of the Modified Method Five (MM5) sampling and analysis scheme for polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/PCDF) in municipal waste combustor stack gas have been determined. This was accomplished using a dynamic spiking system designed to continuously deliver stable isotopic PCDD/PCDF congeners into the MM5 sampling train upstream of the particulate filter during sampling of incinerator stack gas. Field validation tests to measure the recovery of statically and dynamically spiked PCDD/PCDF during stack gas sampling indicated that the resin effectively retained the static spike during operating conditions. Dynamic spike recoveries were inadequate, partially due to the use of dichloromethane as the extraction solvent. Toluene was subsequently shown to be more appropriate than dichloromethane for obtaining enhanced recoveries of PCDD/PCDF. The overall sampling and analysis scheme as recommended in the report was estimated as at better than 80% for the accuracy and as at + or - 35% for the precision.
