The homologue and congener profiles of PCDDs/PCDFs were characterized for various emission sources in an industrial complex in the west of Seoul, the capital of Korea, in order to identify the own profile and to compare the emission characteristics at each emission source. Waste incinerators and manufacturing industrial plants were identified as the major emission sources. PCDDs/PCDFs were sampled three times from stack emission of each facility and all congeners of PCDD/PCDF were analyzed. The homologue profile was calculated as the ratio of the concentration of each homologue to the total concentration of all homologues. The congener profile was calculated as the ratio of the concentration of each 2,3,7,8-substituted congeners to the total concentration of homologues from Cl₄DDs/DFs to Cl_(8)DDs/DFs. The congeners from Cl₁DDs/DFs to Cl₃DDs/DFs were emitted more from manufacturing industry sources and the congeners from Cl₄DDs/DFs to Cl_(8)DDs/DFs were emitted more from waste incineration sources. The homologue profiles and congener profiles by concentration were different according to emission sources, but the congener profiles by toxic equivalents (TEQ) value were similar among the sources. Therefore, PCDDs/PCDFs profiles in various emission sources could be characterized with homologue profiles and congener profiles by concentration, but not by the congener profile with TEQ value.
