Abstract

This study was conducted to estimate the heavy metal contents in various foods (n=696). The contents of lead (Pb), cadmium (Cd) and tin (Sn) were determined using and ICP (inductively coupled plasma spectrometer). The content of mercury (Hg) was determined using a mercury analyzer. The values of heavy metals in canned foods were as follows [minimum-maximum (mean), mg/kg]; Pb 0.001${\sim}$0.36 (0.10), Cd 0.001${\sim}$0.10 (0.04), Sn 0.01${\sim}$24.75 (2.60). The mean values of Pb and Cd in animal foods were 0.40 mg/kg and 0.03 mg/kg. Also, the mean values of heavy metals in vegetables and potatoes were 0.03 mg/kg for Pb, 0.02 mg/kg for Cd, 0.001 mg/kg for Hg, respectively. The mean values of Hg in fishes and canned fishes were 0.08 mg/kg and 0.04 mg/kg. Our results showed that heavy metal contents in various foods available on markets were similar to those reported in other countries.

본 연구는 우리나라에서 유통되고 있는 여러 가지 식품 중에 함유된 중금속 함량을 동시에 분석하여 종합적으로 평가하고자 수행하였다. 우리나라 전국 각 지역의 주요 시장 등에서 채취한 총 696건의 식품 및 가공식품을 습식분해하여 ICP를 이용하여 납, 카드뮴 및 주석 함량을 측정하였고, Mercury analyzer를 이용하여 수은 함량을 측정하였다. 통조림 식품 중 평균 중금속 함량은 납 0.10mg/kg, 카드뮴 0.04mg/kg, 주석 2.60mg/kg으로 나타났다. 육류 및 어패류 중 평균 중금속 함량은 납 0.40mg/kg, 카드뮴 0.03mg/kg이었으며 채소류에서는 납 0.03mg/kg, 카드뮴 0.02mg/kg, 수은 0.001mg/kg으로 나타났다. 어류 및 어류 통조림의 평균 수은 함량은 각각 0.08mg/kg, 0.04mg/kg이었다. 본 조사결과는 국내 외 조사에서 보고된 함량과 비슷한 것으로 나타났다.
