The effect of simulants, repeated use, washing, and oiling on the release of toxic metals from metallic kitchen utensils was investigated. The release of As, Cd, Cr, Ni, and Pb from kitchen utensils composed of stainless steel, aluminum, copper alloy, and cast iron into food simulants was quantified using inductively coupled plasma-mass spectrometry. The results show that this release of toxic metals was highly dependent on pH. Generally, the release of toxic metals tended to decrease with repeated use, and the release of Cr and Ni from stainless steel samples was significantly higher in the first test, compared to the third test. The washing conditions affected the release of As and Cr, whose release levels were higher when washing only with water and with a steel wool pad, respectively. Furthermore, oiling cast iron cookware reduced the release of As, Cd, Cr, and Ni into acidic simulants by 66%, 83%, 71%, and 15%, respectively. The margin of exposure (MOE) was calculated for each toxic metal; the calculated MOE values indicated that it is improbable that the current level of exposure from metallic kitchen utensils would pose a health risk in Korea.
研究了模拟物、重复使用、清洗和涂油对金属厨具中有毒金属释放的影响。使用电感耦合等离子体质谱法定量分析了不锈钢、铝、铜合金和铸铁制成的厨具中砷、镉、铬、镍和铅在食品模拟物中的释放情况。结果表明，这种有毒金属的释放高度依赖于 pH 值。一般来说，随着重复使用次数的增加，有毒金属的释放量趋于减少，与第三次测试相比，不锈钢样品中铬和镍的释放量在第一次测试中显著更高。清洗条件会影响砷和铬的释放，仅用水和钢棉垫清洗时，砷和铬的释放水平更高。此外，给铸铁炊具上油可将酸性模拟物中砷、镉、铬和镍的释放量分别减少 66%、83%、71%和 15%。计算了每种有毒金属的暴露量边际（MOE）；计算得出的 MOE 值表明，目前从金属厨具中接触到的有毒金属水平不太可能对韩国的健康构成风险。
