Abstract
This study was conducted to estimate the contents of heavy metals including lead, cadmium, arsenic and total mercury in alcoholic beverages in Korea. Concentration of Hg was analyzed by gold amalgamation method, using mercury analyzer, while concentration of Pb, Cd and As was analyzed by ICP-MS. Concentration (${\mu}g/kg$) of heavy metal in fermented liquors were; for Pb $9.9\;{\pm}\;8.4$(0~38.0), Cd $5.8\;{\pm}\;4.9$(0~5.4), As $28.6\;{\pm}\;19.4$(1~96.4), Hg $0.7\;{\pm}\;1.2$(0~10.6). Concentration (${\mu}g/kg$) of distilled liquors were ; for Pb $4.4\;{\pm}\;5.7$(0~29.3), Cd $2.0\;{\pm}\;2.5$(0~10.3), As $12.0\;{\pm}\;17.0$(0~95.6), Hg $0.2\;{\pm}\;0.3$(0~2.3). Concentration(${\mu}g/kg$ of other liquous were ; for Pb $7.5\;{\pm}\;5.1$(0~13.7), Cd $5.8\;{\pm}\;3.9$(0.6~11.2), As $25.2\;{\pm}\;39.0$(0.5~103.3), Hg $0.3\;{\pm}\;0.1$(0.1~0.5). The present study showed that difference of the amount of constituent in a same category of food are not affect to the content of heavy metals among them. The residual levels of takju, yakju, sake, beer, fruit wine, soju, whiskey, brandy, general distilled liquor, liquor, other liquors are within the maximum levels, prescribed by Korea food code. It is given that heavy metal exposure of Pb, Cd, As, Hg from consumption of alcoholic beverages (takju, yakju, sake, beer, fruit wine, soju, whiskey, brandy, general distilled liquor, liquor, other liquors) are less than 0.03%, 0.06%, 0.01%, 0.01% (mean) in provisional tolerable weekly intake (PTWI) respectively, indicated by FAO/WHO.
한국인의 주류 섭취로 인한 중금속 위해 영향 여부를 파악하기 위하여 국내산 및 수입산 주류를 대상으로 납, 카드뮴, 비소 및 수은을 분석하고, 일일식품섭취량을 고려하여 이 들 식품 섭취에 대한 위해 평가를 수행하였다. 시료 분석결과로 발효주류 중 납 함량은(${\mu}g/kg$) 11.1(N.D~66.5), 카드뮴 7.6(N.D~47.1), 비소 24.6(1~140.0), 수은 $0.7\;{\pm}\;1.2$(N.D~10.6), 증류주류 중 납 함량은(${\mu}g/kg$) 9.1(N.D~33.4), 카드뮴 1.8(N.D~19.6), 비소 14.9(N.D~209.7), 수은 0.3(N.D~2.3)이었으며 기타주류 중 납 함량은(${\mu}g/kg$) 14.0(N.D~37.8), 카드뮴 10.3(0.6~17.4), 비소 33.6(0.5~103.3), 수은 0.3(0.1~0.5)이었다. 본 연구에서 얻어진 탁주, 약주, 청주, 맥주, 과실주, 소주, 위스키, 브랜디, 일반증류주, 리큐르, 기타주류 중 중금속 함량은 국내 외 문헌들과 유사하거나 낮게 확인 되었으며, 식품별 1일섭취량을 고려한 납, 카드뮴, 비소 및 수은의 주간섭취량은 FAO/WHO의 PTWI와 비교할 때 각각 0.03%, 0.06%, 0.01%, 0.01%이하로 안전한 수준으로 판단된다.
