Abstract
Eggs have been used successfully as a non-destructive monitoring tool for persistent organic
pollutants (POPs) and heavy metals. Seabird eggs have long been used as biomonitors for longterm
monitoring of environmental contaminants in theEurope and North America. In South
Korea, national monitoring program on environmental contaminants has been run primarily for
coastal sediment and bivalves, while biomonitoring program for high-tropic marine species such
as marine mammals and seabirds has not been established yet. The purpose of this study was
to monitor seabird eggs inhabiting along the Korean coasts to identify the levels and profiles of
contaminants. Black-tailed gull eggs were collected from breeding places located in the southern
(Hongdo Island), eastern (Dokdo Island), and western (Seomando Island) coasts of South Korea and
egg content was used for chemical analysis. Among the target analytes, PCBs and DDTs showed
highest levelsat all sites, indicating their great bioaccumulation and biomagnification potential.
The concentrations of PBDEs and HBCDs in eggs were found to be relatively higher at Seomando
compared to other two sites and the levels of PCBs and OCPswere similar among locations. The
concentrations of PBDEs and HBCDs were still lower than PCBs and DDTs, but relatively higher
than other POPs. The relatively persistent isomers or congeners of each compound such as p,p’-
