Co-planar PCBs(polychlorinated biphenyls) of non-ortho are investigated in soil and ginseng on the North Gyeongbuk with HRGC/HRMS. PCB77 in soil on Yeongju and Sangju are detected 0.0007 pgTEQ/g and 0.0009 pgTEQ/g, respectively. PCB81 in soil on Yeongju and Sangju are detected 0.0113 pgTEQ/g and 0.0108 pgTEQ/g, respectively. Also PCB126 in soil on Yeongju and Sangju are detected 0.0907 pgTEQ/g and 0.0944 pgTEQ/g, respectively. But PCB169 in soil on Yeongju and Sangju is not detected. Total Co-planar PCBs of non-ortho in soil on Yeongju and Sangju are 0.1027 pgTEQ/g and 0.1061 pgTEQ/g, respectively. PCB77 in ginseng on Yeongju and Sangju are detected 0.0008 pgTEQ/g. Then PCB81 in ginseng on Yeongju and Sangju are detected 0.0104 pgTEQ/g and 0.0112 pgTEQ/g, respectively. But PCB126 in ginseng on Yeongju and Sangju are detected 0.0585 pgTEQ/g and 0.0579 pgTEQ/g, respectively. PCB169 in ginseng on Yeongju and Sangju is not detected.
