Abstract

There are few studies on toxic metals in fruits. Therefore, we examined contents of toxic metals in fruits (n=386) available in Korean markets. The samples were digested with acids, then analyzed by inductively coupled plasma spectrometer (ICP) or atomic absorption spectrophotometer (AAS) for lead (Pb), cadmium (Cd), and arsenic (As). The contents of mercury (Hg) were also determined using a mercury analyzer, Contents of toxic metals in fruits were as follows [minimum-maximum (mean), mg/kg]; Hg 0.0001-0.019 (0.001), Pb 0.001-0.410 (0.013), Cd 0.001-0.035 (0.000), and As 0.001-0.210 (0.017). Our results showed that metal contents in fruits in Korean markets were similar to those reported in other countries. Average weekly intakes of Hg, Pb, and Cd from fruits are about 1-2% of Provisional Tolerable Weekly Intakes (PTWI) set by FAO/WHO Joint Food Additive and Contaminants Committee for safety evaluation.

본 연구는 우리나라에서 유통되는 과일류 중 유해중금속 함량을 파악하여 각국의 모니터링 및 기준과 비교함으로써 안전성을 평가하고자 하였다. 9종(386건)의 과일류에 대하여 4개 금속(Hg, Pb, Cd, As) 함량을 수은은 Mercury Analyzer로 납, 카드뮴, 비소는 습식분해 후 ICP 및 AAS로 분석하였다. 본 연구결과로부터 알아 낸 국내에서 유통되는 과일류 중 유해중금속 평균함량은 Hg 0.001 mg/kg, Pb 0.013 mg/kg, Cd 0.006 mg/kg, As 0.017 mg/kg으로 외국에서 보고된 결과와 유사한 수준이었다. 또한 우리나라 국민이 과일류를 통해 섭취하는 수은, 납, 카드뮴 등 유해중금속량은 FAO/WHO에서 설정한 잠정주간섭취허용량(PTWI)의 약 1-2% 수준으로 낮게 나타났다.
