Abstract

This study investigated the migration levels of lead (Pb), cadmium (Cd), and arsenic (As) from food contact articles (glassware, ceramics, enamelware, and earthenware) into a food stimulant (4% v/v, acetic acid). Migration tests were performed at 25℃ for 24 h and all analyses were performed using Inductively-Coupled Plasma Mass Spectrometry (ICP-MS). The method was validated by linearity of calibration curves, limit of detection (LOD), limit of quantification (LOQ), recovery, precision, and uncertainty. In glassware, the migration concentrations ranged from not-detected (N.D.) to 752.21 ㎍/L and N.D. to 1.99 ㎍/L for Pb and Cd, respectively. In ceramics, the migration concentrations ranged from N.D. to 1,955.86 ㎍/L, N.D. to 74.06 ㎍/L, and N.D. to 302.40 ㎍/L for Pb, Cd, and As, respectively. In enamelware, the migration concentrations ranged from N.D. to 4.48 ㎍/L, N.D. to 7.00 ㎍/L, and N.D. to 52.00 ㎍/L for Pb, Cd, and Sb, respectively. In earthenware, the migration concentrations ranged from N.D. to 13.68 ㎍/L, N.D. to 0.04 ㎍/L, and N.D. to 6.71 ㎍/L for Pb, Cd, and As, respectively. All results were below the migration limits of Korea standards and specifications for food utensils, containers, and packages.

국내에 유통되는 식품용 기구 및 용기·포장 중 4종류(유리제, 도자기제, 법랑 및 옹기류) 의 재질, 총 198건을 수거하여 식품으로 이행 가능성이 있는 중금속(납, 카드뮴, 비소 및 안티몬)에 대하여 이행량을 ICP-MS 로 조사하였다. 식품유사용매는 4% 초산을 사용하여 25℃를 유지하면서 24시간 방치한 액을 시험용액으로 하였으며, 시험법 검증을 위하여 검량선, 검출한계, 정량한계, 회수율, 정밀성 및 측정불확도를 산출하였다. 이행량 조사 결과 유리제의 경우 납과 카드뮴은 각각 N.D.-752.21 ㎍/L, N.D.-1.99 ㎍/L 이고, 도자기제는 납, 카드뮴 및 비소가 각각 N.D.-1,955.86 ㎍/L, N.D.-74.06 ㎍/L, N.D.-302.40 ㎍/L 이며, 법랑의 납, 카드뮴 및 안티몬은 각각 N.D.-4.48 ㎍/L, N.D.-7.00 ㎍/L, N.D.-52.00 ㎍/L 이였다. 그리고 옹기류의 납, 카드뮴 및 비소는 각각 N.D.-13.68 ㎍/L, N.D.-0.04 ㎍/L, N.D.-6.71 ㎍/L 수준으로 확인 되었다. 이와 같은 결과를 근거로 유리제 등으로부터 식품으로 이행 가능한 중금속의 위해도는 총 섭취량대비 4.83% 이하로 비교적 안전한 것으로 판단된다. 또한, 본 연구결과는 국내에서 유통중인 유리제 등의 식품용 기구 및 용기·포장은 모두 국내의 기준·규격에 적합함을 확인하였다.
