2. Semi-quantitative Aroclor congener distributions

Abstract

Weight percents of PCB congeners in Aroclors 1221, 1016, 1242, 1254, 1260, and 1262 were determined by separately averaging resolved peaks quantified against standards of all 209 congeners in 9 HRGC-ECD and 9 HRGC-MS systems. A separate pair of systems provided nearly complete profiles of Aroclors 1232 and 1248. The tabulated values lack sufficient accuracy to qualify the Aroclors as secondary standards for comprehensive, quantitative, congener-specific analyses, but they provide more complete and accurate semi-quantitative characterizations of congener distributions for a larger number of Aroclors than prior publications.
