Description Many sites in the USA are contaminated with polychlorinated biphenyls (PCBs). Chemical analysis to determine total PCBs traditionally used Aroclor based analytical methods that can be problematic due to many reasons including identification and fate and transport issues. More recent methods using high resolution gas chromatography/mass spectrometry (HRGC/MS) can analyze 209 PCB congeners and provide better detection and quantification of total PCBs. Therefore, many new investigations are using congener analysis in addition to old Aroclor data. This poster looks into the relationship between paired Aroclor and congener data, shows methods to translate these data from one to another, and discusses the usefulness of such transformation.
