Abstract An in-laboratory validated method for identification and quantitation of sterols and triterpene diols was used to determine the relative composition of identifiable sterols and triterpene diols in 13 vegetable oils and quantitate these components in multiple samples of 6 vegetable oils: extra virgin olive, pomace olive, corn, cottonseed, canola, and evening primrose oils. Erythrodiol, a triterpene diol present in all olive oils, was also found in cottonseed oil.

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.
