- Abstract
Results are reported of a pilot survey of concentrations of polybrominated diphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) in shark liver oil supplements. Eleven brands of dietary supplements were analysed using an isotope dilution GC/MS method. Total concentrations of 10 PBDE congeners (BDE-28, -47, -49, -66, -99, -100, -153, -154, -155 and -183) ranged from 0.1 to 53 ng g-1 oil weight and total concentrations of six PCB congeners (CB-28/31, -52, -118, -153 and -180) in the samples ranged from 16 to 340 ng g-1 oil weight (undetected values are not included). Two brands of Japanese deep-sea shark liver oil contained the highest levels of PBDEs (49-53 ng g-1 oil weight) and PCBs (290-340 ng g-1 oil weight). These results indicate that PBDEs may have entered Japanese deep-sea waters.
