Polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) and polychlorinated biphenyls (PCBs) are concerned compounds among 12 persistence organic pollutants of the Stockholm convention. These compounds can increase the risk of cancer and cause damage to immune system. The number of 17 PCDD/Fs has TEF (toxic equivalence factor) for calculation of TEQ value. Among the total 209 PCBs, only 12 PCBs congeners which have dioxin-like toxicity are classified as DL-PCBs. The amount of intake and exposure from plant-based food groups has large proportion in Korea due to the dietary habit. Plant-based samples (46 species, total 415 samples) collected in six cities have been analyzed for a range of dioxins (29 congeners; PCDD/Fs 17 congeners and dioxin-like PCBs 12 congeners) using the isotope dilution method in HRGC/HRMS. For the test method validation, certified reference materials were analyzed. Based on the measured dioxins levels, average daily dietary intake estimates of dioxins were calculated. For risk assessment of PCDD/Fs and DL-PCBs, the data of daily intake from Korea National Health and Nutrition Examination Survey (2008~2010) are considered. As a result of estimated daily intake and TEQ value, total amount of PCDD/Fs and DL-PCBs exposure to Korea general population was 0.044 pg-TEQ/kg bw/day. On account of Korean TDI (tolerable daily intake) is 4 pg-TEQ/kg bw/day, compared to TDI, daily intake of dioxins via fish ingestion was 0.11%.
