AN323: Extraction of Polychlorinated Dibenzo-p-dioxins and Polychlorinated Dibenzofurans from Environmental Samples Using Accelerated Solvent Extraction (ASE)
DescriptionPolychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are toxic at low concentrations and therefore highly regulated. Additionally, these contaminants are difficult to extract. Accelerated Solvent Extraction (ASE) is an equivalent extraction method for U.S. EPA Methods 3545. ASE uses solvents at elevated temperatures and pressures, thereby increasing the extraction efficiency while consuming small amounts of solvent at significantly less time. Here ASE has been used to extract PCDDs and PCDFs from ground chimney brick, urban dust, fly ash, and sediment samples.
