| 摘 要： | 用气相色谱-质谱联用仪测定了一只中国东海海域抹香鲸(Physeter macrocephalus)皮脂24种多氯联苯(PCBs)同系物的含量,并分析了其组成特征以及国际毒性当量.结果表明,东海海域抹香鲸皮脂PCBs的湿重含量为1.12μg.g-1;PCBs同族体中以含6和5个氯原子的化合物为主,高氯代PCBs占总量的92.10%;PCBs同系物中以PCB153、PCB138、PCB101和PCB149居多,分别占到PCBs总量的21.28%、15.97%、10.29%和10.23%;抹香鲸皮脂的TEQs含量为1663.07 pg.g-1,其毒性主要来自PCB126,其次是PCB123和PCB118;初步推断中国东海海域的抹香鲸受PCBs污染程度较轻.

| Abstract: | Residues of 24 polychlorinated biphenyls(PCBs) in the blubber of a sperm whale(Physeter macrocephalus) from East China Sea were analyzed by GC/MS.The composition characteristics and toxic equivalency of PCBs in the blubber of sperm whale were analyzed.The results showed that the total PCBs content in the blubber was 1.12 μg · g-1 wet weight.Hexachlorobiphenyls and pentachlorobiphenyls were the main PCBs congeners.More than 92.10% of the PCBs congeners contained five chlorine atoms or more.The concentrations of PCB153,PCB138,PCB101 and PCB149 were 21.28%,15.97%,10.29% and 10.23%.The TEQ of PCBs in blubber was 1663.07 pg · g-1.Preliminary inference was that the sperm whale from East China Sea was mildly contaminated by PCBs. |
