By using internal standard method based on gas chromatography-electron capture detector （GC-ECD）, the contents of persistent or- ganochlorine pollutants polychorinated biphenyls （PCBs） and organochlorine pesticides （OCPs） in eggs of seabirds （ Catharacta Ionnbergi, Cathar- acta maccormicki, Pygoscelis papua and Macronectes giganteus） breeding on King George Island, Antarctica were detected, and their ecological environment significance was discussed. The results showed that the recovery of various compounds ranged from 68.6% to 90.8% ; relative stand- ard deviation （RSD） was 3.6%, and the lowest detection limits of PCBs and OCPs were 0.8 - 16 and 2 - 12 pg respectively, which could meet the demands for the residue analysis of trace persistent organochlorine pollutants in the eggs of Antarctic seabirds. The contents of PCBs, DDTs, HCB and HCHs in the eggs of Antarctic seabirds were 0.5 -515.5, 2.0 -304.4,0.5 -70.5, and 0.5 -2.0 ng/g respectively. In addition, the accumula- tion of PCBs and OCPs in the skuas was enhanced gradually through the food chain. The maximums of persistent organochlorine pollutants ap- peared in the eggs of C. Ionnbergi, followed by the eggs of C. maccomicki. The detection of OCPs and PCBs in the eggs of Antarctic seabirds was not interfered by other compounds containing chlorine, showing that the extraction, purification and detection method was suitable for the analysis of OCPs and PCBs in the eggs of Antarctic seabirds and has high sensitivity and reliability.
