The accumulations of semivolatile organic compounds (SOCs) were quantified in notothenioid fish collected in King George Island. The SOCs distribution in body tissue like muscle, liver, gonads and gills were also analyzed. The results show that PCB levels were about 36% of total contaminant load followed by PBDEs and DDT. For some classes of SOCs (e.g. PCBs, HCH and DDTs), concentration levels seem to increase slightly in gonads and for others (e.g. HCB, PBDEs and TN), the highest values were in gills. Our data suggest that Antarctic fish is exposed to SOCs and the target tissues are gonads and gills.
