Abstract

Polychlorinated dibenzo-p-dioxins(PCDDs), dibenzofurans(PCDFs), and biphenyls(PCBs) were analyzed by HRGC/HRMS in human blood samples from the Siwha industrial area in Korea. The PCDD/F and PCB concentrations in workers were higher than those in residents. The average TEQ concentrations of PCDD/Fs in workers and residents were 40.3 pg I-TEQs/g lipid and 16.6 pg I-TEQs/g lipid, respectively, and the total PCB concentrations were 174.1 ng/g lipid and 151.0 ng/g lipid, respectively. When applied to principal component analysis, the PCDD/F congener distributions of workers were differentiated from those of residents. But, all of them were similar to the distribution in several Korean foods. Estimated daily intake(EDI) of each person was calculated, and then only 40% to the total people were within the tolerable daily intake range(1-4pg I-TEQ/kg bw/day) suggested by WHO(1997).
