A study on the determination method of PCBs(polychlorinated Biphenyls) content in polystyrene(PS) materials by GC/MS was performed. The toluene was selected for the extraction of PCBs in plastics and the best extraction time was 4 hours. The artifact materials produced from polystyrene with 2,2’,3,4,4’,5,5’-heptachlorobiphenyl standard solution were examined by homogeniety test. PCBs in average concentration of 118 mg/kg were quantitatively determined for the artifact materials by applying our procedure in interlaboratory comparison test.
