Abstract

Atmospheric levels of polychlorinated biphenyls (PCBs) at the King Sejong station were monitored for one year using passive air samplers. Low-chlorinated PCB homologues were predominant in all samples. PCB levels were observed to decrease with distance from the station, which may indicate that a significant part of PCBs could be of local origin. Although the level of PCBs at the King Sejong station is very low (${\Sigma}_9PCB$ (18, 52, 101, 118, 128, 138, 153, 180, 187): $2.3\;pg\;m^{-3}$) probably due to decrease in the global PCB emissions, it is one order of magnitude higher than a background level in the Antarctic. Based on this preliminary study, more interpretation on PCB data and meteorological conditions is required.
