Notes:
A method is described for the analysis of contaminated building dust samples and surface swab samples for octachlorodibenzo-p-dioxin (OCDD) and heptachlorodibenzo-p-dioxins (HpCDDs). The samples were analyzed by fused silica capillary GC combined with electron capture detection. Analysis was preceded by a short HPLC cleanup step designed to remove polychlorinated biphenyls (PCBs) and other compounds that might interfere. The method was found to work successfully on surface swab and dust samples known to contain PCBs, OCDD, and HpCDDs. The overall recovery of the analysis procedure for OCDD was found to be approximately 80%. The detection limit for the method was sample dependent, but for one typical set of surface swab samples was 0.2 μg/m2 of OCDD.
