SW-846 Test Method 4025: Screening for Polychlorinated Dibenzodioxins and Polychlorinated Dibenzofurans (PCDD/PCDFs) by Immunoassay

This method is a procedure for the analysis of polychlorinated dibenzodioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) in soil at 500 parts per trillion (picograms per gram) using a simple one-step liquid phase oxidative cleanup or, at mid to low ppt levels, using a two step coupled column cleanup (oxidation and activated carbon binding) adapted from Method 8290.
