Concentrations of polychlorinated biphenyl congeners (PCBs) in samples collected from 43 kindss of water, 35 kinds of soil and 11 kinds of sediment in various place of Korea have been monitored using GC/MS/SIM analytical method. In our investigation, mean recoveries were <TEX>$83.8{\pm}10.4%$</TEX> for water, <TEX>$94.9{\pm}12.2%$</TEX> for soil and sediment samples and <TEX>$80.2{\pm}8.7%$</TEX> for the spiked <TEX>$^{13}C{_{12}}$</TEX>-PCBs. Detection limits of PCBs for water, soil and sediment samples are 0.01 ng/ml and 0.05 ng/g. PCB congeners in water samples were not detected within quantitation limit, but trace amounts were detected in most of soil and sediment samples. The contamination level of PCBs in Korea was evaluated to be lower than in advanced countries like USA, Europe and Japan.
