Abstract

This study was conducted to examine the contents of heavy metals in beverages and to estimate their intakes. The contents of lead (Pb), cadmium (Cd), arsenic (As), and tin (Sn) were determined in a total of 207 samples of beverages using atomic absorption spectrophotometer(AAS) and inductively coupled plasma spectrometer(ICP). Also a mercury analyzer was utilized for analysis of mercury. The values of heavy metals in beverages were as follows [min-max (mean), mg/kg]; Hg 0.0001-0.0025 (0.0004), As ND-0.0245 (0.0003), Pb ND-0.089 (0.004), Cd ND-0.006 (0.001), Sn ND-45.36 (1.97). Our results were similar to those reported by other countries. Our weekly intakes of heavy metals from beverages take $0.01%{\sim}0.06%$ of PTWI (Provisional Tolerable Weekly Intake) established by FAO/WHO.

본 연구는 국내 유통되고 있는 207건의 음료류에 대하여 납, 카드뮴, 비소, 주석함량은 습식분해 후 유도결합플라스마분광기(ICP), 원자흡광광도계(AAS)를 사용하여 분석하였으며 수은함량은 수은분석기 등을 이용하여 측정하였다. 그 결과는 다음과 같다. [단위: min-max(mean), mg/kg]; Hg 0.0001-0.0025(0.0004), As 불검출-0.0245(0.0003), Pb 불검출-0.089(0.004), Cd 불검출-0.006(0.001), Sn 불검출-45.36(1.97). 본 조사결과 우리나라에서 유통되고 있는 음료류 중 납 등 중금속 함량은 외국의 모니터링 결과와 유사하였다. 또한 우리나라 국민이 음료류를 통한 중금속 섭취량은 FAO/WHO에서 설정한 잠정주간섭취허용량의 약 $0.01{\sim}0.06%$ 이하로 매우 낮았다.
