HPLC/FLD를 이용하여 곡류, 견과류 등 총 565건을 대상으로 총 아플라톡신 함량을 조사하여 노출량을 평가하였다. B와 G 그룹의 검출한계는 각각 0.05, 0.07 ng/g이였고, 쌀, 땅콩버터 및 고춧가루에 대한 아플라톡신($B_{1}$, $B_{2}$, $G_{1}$ 및 $G_{2}$)의 회수율은 양호한 수준이었다. 총 아플라톡신은 전체 시료 565건 중 27건(4.77%)이 검출되었으며, 검출빈도는 곡류 0.17%, 견과류 0.35%, 가공식품 3.01%, 기타식품 1.24%을 보여주었고, 두류 및 건조과일류는 검출되지 않았다. 식이섭취량을 고려한 총 아플라톡신의 1일 1인당 평균섭취량은 0.04 ng/kg bw/day이였다.
A survey of total aflatoxin levels was conducted on 565 food samples (cereals, nuts, etc) collected in commercial markets. The determination of aflatoxins ($B_{1}$, $B_{2}$, $G_{1}$ and $G_{2}$) was performed using HPLC with fluorescence detector. The Limit of Detections (LODs) of the B group and G group were 0.05 ng/g and 0.07 ng/g, respectively. In addition, recoveries of rice, peanut butter, and red pepper flour were satisfactory. Total aflatoxin was detected 27 samples(4.8%) out of 565 samples. Incidence ratios in cereals, nuts, processed products, and other foods were 0.2, 0.4, 3.0 and 1.2%, respectively, but aflatoxin was not detected in pulse and dried fruits. The daily intake of total aflatoxin using food intakes was 0.04 ng/kg bw/day.
