This study assessed concentrations in and intake of toxic and essential elements from formulas and foods intended for infants during their first 6months of life. Concentrations of the essential elements Ca, Fe, Zn, Mn and Mo were significantly higher in most formulas than in breast milk. Daily intake of Mn from formula varies from ten up to several hundred times the intake of the breast fed infant, levels that may be associated with adverse health effects. One portion of infant food provided significantly more Fe, Mn, Mo, As, Cd, Pb and U than one feeding of breast milk, but less Ca, Cu and Se. Rice-based products in particular contained elevated As concentrations. Drinking water used to mix powdered formula may add significantly to the concentrations in the ready-made products. Evaluation of potentially adverse effects of the elevated element concentrations in infant formulas and foods are warranted.
本研究评估了婴儿出生后头 6 个月配方奶和食物中有毒和必需元素的浓度和摄入量。在大多数配方奶中，必需元素钙、铁、锌、锰和钼的浓度明显高于母乳。从配方奶中摄入的锰量是母乳喂养婴儿的十倍到数百倍不等，而这些水平可能与不良健康影响有关。婴儿食品的一份摄入量显著高于母乳喂养婴儿摄入的铁、锰、钼、砷、镉、铅和铀，而钙、铜和硒的摄入量则较低。特别是以大米为基础的产品砷含量较高。用于冲调配方奶粉的饮用水可能会显著增加即食产品中的浓度。有必要评估婴儿配方奶和食品中升高的元素浓度可能产生的不良影响。
