Polybrominated biphenyls (PBBs) are a class of brominated hydrocarbons with 209 possible compounds, referred to as PBB congeners. PBBs are lipophilic compounds with a low vapour pressure and low water solubility which decreases with increasing degree of bromination and chemically stable, persistent in the environment and bioaccumulative. Especially, hexabrominated bipheyls (HBBs) of PBBs are most widely used for plasticizers and flame retardants were designated as persistent organic pollutants (POPs) by Stockholm Convention in 2009. As a part of the food safety management of POPs, six PBBs which are mainly concerned and prioritized to investigate, were monitored from domestically distributed fisheries and animal products in Korea. Gas liquid chromatography-high resolution mass spectrometry was used with selected ion monitoring and stable isotope dilution method (GC-HRMS-SIM) for qualification and quantitation. LODs and LOQs were set at the levels of 3 pg/g and 10 pg/g on the wet weight basis, respectively. Frequencies of occurrence of PBBs from the 154 foods; 77 fisheries and 77 animal products, were 6.7 % in fisheries, and 2.4 %, respectively in animal product with detection of different congeners below or at the levels of LOQs.
