本研究的目的是评估波兰市场上婴儿配方奶粉中13种必需和有毒元素（As、Cd、Co、Cr、Cu、Fe、Mn、Mo、Ni、Pb、Se、V、Zn）的水平。选定的食物样本来自动物（牛奶和山羊奶）和植物（豆奶、低过敏产品、谷物粥）。采用电感耦合等离子体质谱（ICP-MS）和中子活化分析（NAA）两种分析技术，对16种0 ~ 8个月婴儿配方奶粉中的元素含量进行了分析。对于砷的测定，也使用了NAA的放射化学模式。对0- 8月龄非母乳喂养婴儿某些微量营养素的日摄入量进行了估算，并与现行安全限值进行了比较。已使用经认证的参比物质（CRM）进行方法验证：脱脂奶粉1549（国家标准局NBS）、大豆粉INCT-SBF-4（核化学与技术研究所INCT）、米粉SRM 1568 b（国家标准与技术研究所NIST）。
The aim of this study was to assess the levels of 13 essential and toxic elements (As, Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb, Se, V, Zn) in the infant formulas, available on Polish market. Selected food samples were of animal (cow- and goat-based milks) and plant (soy-based milk, hypoallergic products, grain porridges) origin. Two analytical techniques, inductively coupled plasma mass spectrometry (ICP-MS) and neutron activation analysis (NAA), have been complementarily applied to analyze elemental content of 16 formulas dedicated for infants between 0 and 8months. For arsenic determinations, the radiochemical mode of NAA was also used. The daily intake of some micronutrients in the age 0-8months for non-breastfed infants was estimated and compared with present safety limits. Certified reference materials (CRMs) have been used for the validation of the methods: Non-fat Milk Powder 1549 (National Bureau of StandardsNBS), Soya Bean Flour INCT-SBF-4 (Institute of Nuclear Chemistry and TechnologyINCT), Rice Flour SRM 1568b (National Institute of Standards and TechnologyNIST).
