In PCB treatment plant, it is necessary to monitor the performance of the plant in terms of both destruction efficiency and effects to the surrounding environment. Development of a rapid PCB analytical method is needed for the standpoint of safety management because the present official standard method takes several days for the analysis. In the present study, rapid analytical methods have been developed for PCB monitoring in organic solvent and wastewater. The established method for the PCB in organic solvent consists of HPLC-clean up and largevolume injection GC/MS analysis, and could analyze samples within 2 hours with quantification limit less than 0.1mg/kg and C.V. within 5%. A combination of solid-phase extraction and precut GC-ECD was selected for PCB analysis in waste water with the performance of 2 hours analysis time, quantification limit less than 0.5μg/l and C.V. within 5%. The developed two methods showed satisfactory performance in terms of both correlations with the standard method and applicability to the treatment plant.
