Analytical methodology for polychlorinated dioxins and furans (PCDDs and PCDFs) in pulp and paper related matrices is not standardized. This paper consolidates the work done by many researchers in Canada, US and Europe over the past 10-12 years to develop reliable multi-media methodology at ultra-trace levels. The method presented here uses matrix-specific extraction and cleanup procedures for pulp and paper effluents and receiving waters and can easily be expanded to cover other pulp and paper related matrices and environmental samples. Analyte-specific quantitative analysis utilizes high-resolution capillary column gas chromatography - high resolution mass spectrometry technique for the determination of PCDD and PCDF isomers, with estimated detection limits of 10 Pg/L for 2,3,7,8-TCDD in reagent water.
