초록
4년 동안(2004-2007) 국내 유통중인 식품 총 221건을 구입하여 다이옥신류(PCDD/DF + 다이옥신유사 PCBs)를 동위원소희석법을 이용하여 분석하였고, 한국인의 다이옥신 1일 노출량을 산출하였다. 식품 중 다이옥신류의 검출량은 2004년과 2005년은 오염도 자료에 1998 WHO TEF값을, 2006년부터는오염도 자료에 2005 WHO TEF값을 사용하여 다이옥신류 함량을 산출하였으며, 평균 검출량은 백미는< 0.01 pg TEQ/g, 소고기 0.13 pg TEQ/g, 돼지고기 0.07 pg TEQ/g, 닭고기 0.04 pg TEQ/g, 우유 0.04 pg TEQ/g, 치즈 0.05 pg TEQ/g, 계란(노른자)는 0.13 pg TEQ/g, 수산물 중 고등어는 1.35 pg TEQ/g, 삼치1.03 pg TEQ/g, 갈치 1.00 pg TEQ/g, 조기 0.16 pg TEQ/g, 명태 0.11 pg TEQ/g, 장어 0.52 pg TEQ/g, 굴0.32 pg TEQ/g, 꽃게 0.14 pg TEQ/g 수준으로 조사되었다. 식품을 통한 한국인의 다이옥신류의 노출량은 체중 1 kg 당 1일 0.47 pg TEQ로 다이옥신류의 TDI (4 pg TEQ/kg bw/day) 대비 약 11%수준으로 조사되었으며, 이 수준은 건강상 위해가 없는 것으로 평가되었다.
Abstract
A total 221 samples of the retailed foods collected from 2004 to 2007 was examined to estimate the level of dioxins(29 congeners) by the isotopic dilution method, and the exposure of population of Korean to dietary of dioxins was performed. Dioxins levels were calculated using TEF values established in 1998 and 2005, respectively. The average levels (pg TEQ/g) were less than 0.01 for polished rice, 0.04 (poultry)-0.13 (beef) for meats, 0.04 (milk)-0.05(cheese) for milk and dairy products, 0.13 for egg (york, only) and 0.11 (alaska pollack)-1.35 (pacific mackerel) for fishes. The estimated daily intake of Korean through foods was 0.47 pg TEQ/kg bw/day, and it was estimated as about 11% to tolerable daily intake (TDI; 4 pg TEQ/kg bw/day) of Korea and Japan. Consequently, it was concluded that there was no health risk.
