A simple, sensitive, precise and specific method for the isolation of planar PCB congeners having four, five and six chlorines in environmental samples is presented. On average, recoveries of 3,3,4,4; 3,4,4,5; 3,3,4,45 and 3,3,4,4,5,5 (IUPAC No 77, 81, 126 and 169) planar PCB congeners from spiked Aroclor mixtures were 947.2, 825.4, 933.9 and 962.5%, respectively; while recoveries from spiked dolphin blubber samples were 874.0, 702.3, 912.8 and 972.3%. As compared to previously published methods, this methodology saves both time and materials, i.e. solvents, and eliminate the use of benzene, a highly carcinogenic solvent, which requires extreme care in handling by the analyst. 1991.
