In our analytical investigation, the 24 standard congeners of PBBs were used and were separated using AT-1 column(15 m x 0.25 mm x 0.1 ¥ìm), and were monitored using SIM(Selected Ion Monitoring) method. The mean recoveries were 96.6 % for water, 96.8 % for soil and sediment samples. Detection limits of PBBs in water are 20 ng/L(mono-, di-, tri-, tetra-, penta-, hexa-BB) or 300 ng/L(deca-BB) and those of soil and sediment samples are 3 (mono-, di-, tri-, tetra-, penta-BB), 5 (hexa-BB) and 50 (deca-BB)¥ìg/kg. PBBs congeners in all samples were not detected within quantitation limit, and the contamination level of PBBs in Korea was evaluated to be much lower than that in advanced countries like USA, Japan and European countries.
