Abstract

To investigate concentration and characteristics of Dioxine-like PCBs in soil, Cheongju city, total 28 soil samples were collected. The total and TEQ concentration of 12 DL-PCBs ranged from 10.82 to 234.84 pg/g dry weight (mean conc. 65.07) and from 0.002 to 0.399 pg TEQ/g dry weight (mean conc. 0.062), respectively. These levels are lower or similar that of various soil which were conducted by ministry of environment of Korea from 2005 to 2007. The TEQ concentration as land use was high as follows; industrial area > green area > residential and commercial area > farm land. In terms of congener distribution, the congener profile suggested that DL-PCBs sources could be related to commercial products of PCB.
