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.

Polychlorinated biphenyls (PCBs) are persistent organic pollutants that are linked to adverse health outcomes. PCB tissue levels are determinants of PCB toxicity; however, it is unclear how factors, such as an altered metabolism and/or a fatty liver, affect PCB distribution in vivo. We determined the congener-specific disposition of PCBs in mice with a liver specific deletion of cytochrome P450 reductase (KO), a model of fatty liver with impaired hepatic metabolism, and wildtype (WT) mice. Male and female KO and WT mice were exposed orally to Aroclor 1254, a technical PCB mixture. PCBs were quantified in adipose, blood, brain and liver tissues by gas chromatography-mass spectrometry. PCB profiles and levels in tissues were genotype and sex dependent. PCB levels were higher in the liver from KO compared to WT mice. PCB profiles showed clear differences between tissues from the same exposure group. While experimental tissue : blood partition coefficients in KO and WT mice did not follow the trends predicted using a composition-based model, the agreement between experimental and calculated partition coefficients was still reasonable. Thus, a fatty liver and/or an impaired hepatic metabolism alter the distribution of PCBs in mice and the magnitude of the partitioning of PCBs from blood into tissues can be approximated using composition-based models.<br>
