“…This conclusion is understandable when results are reported on a gravimetric basis without adjusting for loss of water and fat during cooking. Increases in PCBs as high as 36% have been reported in carp when calculated using a mass-balance approach that accounts for weight loss in the fillet (Zabik et al 1982). Initially, they reported that extractability of PCBs is lower in raw tissue than in cooked tissue and recommended four solvent extractions on raw fish to obtain maximum PCB yields.…”

“…We believe these three extractions adequately removed the majority of the available PCBs. Zabik et al (1982) also suggested that extractability of PCBs was related to a high percentage of lipid in the tissue. Their early work with lake trout indicated significant reductions in total PCBs due to cooking when expressed on a mass basis.…”

“…They have been detected in fish (Brunn and Manz, 1982;Wickstrom et al, 1981;Zabik et al, 1982), birds (Barbehenn and Reichel, 1981), and humans (Safe, 1984). Incidents of PCB poisoning have occurred in Japan in 1968 (Urabe and Asahi, 1984) and in Taiwan in 1979 (Lu and Wong, 1984) as a result of ingestion of contaminated cooking oil.…”

The effects of acute exposure to polychlorinated biphenyls (PCBs) on porphyrin synthesis and cytochrome P-450-dependent monooxygenases in the small intestine and liver were studied in male Japanese quail. The birds were dosed orally with the PCB mixture, Aroclor 1242, or the individual PCB isomers, 2,4,2',4'-tetrachlorobiphenyl (2-TCB) and 3,4,3',4'-tetrachlorobiphenyl (3-TCB), and were killed 48 h later. All the PCB compounds caused a significant increase in porphyrin content and delta-aminolevulinic acid synthetase (ALA-S) activity in the small intestine and liver. Increases in porphyrins were greater in the small intestine than in liver. However, a smaller increase in ALA-S activity occurred in the small intestine than in liver, suggesting that ALA-S induction is not a major mechanism for the increased porphyrin content of small intestine. All the test compounds significantly increased the cytochrome P-450 content of liver. In the small intestine, cytochrome P-450 content was increased by Aroclor 1242 and 2-TCB but not by 3-TCB. The activity of 7-ethoxyresorufin O-deethylase, however, was increased by all test compounds in both liver and small intestine. In contrast, there was a striking difference between small intestine and liver in the induction of 7-ethoxycoumarin O-deethylase (ECOD) activity by Aroclor 1242. In the liver, ECOD activity was unchanged or decreased, but in the small intestine, ECOD activity increased linearly with dose. No tissue difference in ECOD activity was observed after treatment with 2-TCB or 3-TCB. These findings suggest that acute exposure to a given PCB results in marked differences between small intestine and liver in porphyrin metabolism and in the induction of cytochrome P-450 isozymes and associated monooxygenases.

“…In preliminary studies using charbroiling of three carp fillets from Michigan rivers, extremely variable but substantial losses of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) ranging from 30 to 70% were recorded (Kaczmar, 1983). This contrasts to the less than 10% loss of polychlorinated biphenyls (PCBs) and chlorinated hydrocarbons during the cooking of carp fillets and salmon steaks from the Great Lakes (Zabik et al, 1982;Smith et al 1973). Nevertheless, Puffer and Gossett (1983) reported that panfrying white croaker reduced DDT compounds by 74% and 39% for fish caught from Santa Monica Bay and in Orange County, respectively.…”
