In this work a determination of selected elements in the infant formulas commercially available on the Polish market was done. 14 different materials (milk-based formulas and grain porridges) were analyzed. Both, inductively coupled plasma mass spectrometry (ICP-MS) and instrumental neutron activation analysis (INAA) were applied for the determination of As, Cr, Fe and Se, which are recognized as the problematic elements for ICP-MS. For As and Se, the radiochemical NAA was also used. The daily intake of Se and Fe in the age 0-6 months for non-breast fed infants was estimated and compared with present safety limits.
在这项工作中，对波兰市场上可买到的婴儿配方食品中的选定元素进行了测定。分析了14种不同的产品（乳基配方奶粉和谷物粥）。电感耦合等离子体质谱法（ICP-MS）和仪器中子活化分析法（INAA）都被用于测定砷、铬、铁和硒，这些元素被认为是ICP-MS分析中的疑难元素。对于砷和硒，还采用了放射化学中子活化分析法。估算了非母乳喂养的0至6个月婴儿的硒和铁的每日摄入量，并与当前的安全限值进行了比较。
