This method is for the quantitative determination of polyhalogentated dibenzo-p-dioxins and dibenzofurans (PHDDs/PHDFs) in ambient air, which include the polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDDs/PCDFs), polybrominated dibenzo-p-dioxins and dibenzofurans (PBDDs/PBDFs), and bromo/chloro dibenzo-p-dioxins and dibenzofurans (BCDDs/BCDFs). The method uses a high volume air sampler equipped with a quartz-fiber filter and polyurethane foam (PUF) adsorbent for sampling 325 to 400 m³ of ambient air in a 24 hour sampling period. The samples are analyzed using high resolution gas chromatography-high resolution mass spectrometry (HRGC/HRMS). The analytical portion of this method is similar to SW-846 8290.
The most common use of the method is for the collection and analysis of polychlorinated dioxins and furans.
