“…Perchlorination (13) has been advocated as the best technique to find the total PCB content to minimize the problem of nonstandard peaks mentioned above. We did not use this technique since not all PCBs are equally toxic (3, 14), and 3,4,5,3,,4/,5'-hexachlorobiphenyl and the 3,4,5,3',4'-and 2,3,4,3',4'-pentachlorobiphenyls being regarded as the most toxic.…”

“…The problems encountered in the quantitation of PCB residues have focused the attention of the analytical chemist on methods by which the concentration of PCBs is related to the estimation of a single species. Such attempts have included: carbon-skeleton GC, where PCBs are reduced oncolumn (5% Pt at 180 °C with H2 as carrier gas) to biphenyl (24); perchlorination of PCBs by antimony pentachloride to yield decachlorobiphenyl (25); and microcoulometric determination of the total chlorine content as HC1 (26). These methodologies have been developed because EC-GC detector response is disproportionate, i.e., highly dependent on the degree of chlorination of the biphenyl nucleus.…”

PCBs Regulatory History and Analytical ProblemsSynthesis of polychlorinated biphenyls (PCBs) was first described by Schmidt and Schultz (i) in 1881, but the industrial application of that discovery was not fully developed until 50 years later by the Swan Corporation. Commercial introduction of PCBs as industrial chemicals for use as nonflammable oils, notably in connection with electrical transformers, condensers, and paint, was begun in 1930. Chlorination of the parent moiety, biphenyl, results in a series of

A suite of chemical and biochemical variables responsive to contaminant exposure was measured in three species of benthic flatfish (English sole, Parophrys vetulus, rock sole, Lepidopsetta bilineata, and starry flounder, Platichthys stellatus) sampled from up to five sites in Puget Sound, Washington, to assess the sensitivity of the parameters to differences in levels of contaminant exposure The examined indexes were levels of (a) polychlorinated biphenyls (PCBs) in liver, (b) fluorescent aromatic compounds in bile, (c) hepatic aryl hydrocarbon hydroxylase and ethoxy‐resorufin O deethylase, (d) total hepatic GSH and (e) hydrophobic DNA xenobiotic adducts in liver as measured by 32P postlabeling The sediment concentrations of PCBs and the sum of selected polycyclic aromatic hydrocarbons at the sampling sites ranged from 21 to 570 and 21 to 5,300 ng/g wet weight sediment, respectively The results showed (a) that all the examined indexes could discriminate among sites exhibiting different degrees of chemical contamination, (b) that species differed in the range of response of most of the measured indexes, and (c) that the use of the indexes in concert appeared to enhance the assessment of contaminant exposure and sublethal effects
