Aroclor 1248

Abstract Columns of activated carbon dispersed on shredded polyurethane foam were used to separate non-o,o´-chlorine (Cl) substituted polychlorinated biphenyls (PCBs) from mg quantities of Aroclors 1016, 1242, 1248, 1254, and 1260. Aroclor 1248 contained the highest concentration (3400 μg/g) of highly toxic 3,4,3´,4´tetrachlorobiphenyl (TCB). Lesser amounts of 3,4,3’,4’-TCB were also found in Aroclors 1242 and 1254. However, we were unable to detect 3,4,3’,4’-TCB in Aroclors 1016 and 1260. Varying amounts of the non-o,o´-Cl substituted 3,4,4´-trichlorobiphenyl and 3,4,3´,4´,5´-pentachlorobiphenyl were found in most of the Aroclor mixtures. No residues of 3,4,5,3´,4´,5´-hexachlorobiphenyl were detected in the Aroclor mixtures examined. Using carbon-foam chromatography and high resolution capillary gas chromatography, 0.11 μg 3,4,3´,4´-TCB/g was detected in 3 subsamples of a composite of 5 carp from the Ohio River.
