采用电感耦合等离子体质谱(ICPMS)、电感耦合等离子体原子发射光谱(ICPAES)和荧光分光光度法对51名日本女性产后5~9天采集的母乳进行了多元素分析。用这些分析方法对牛奶中的31种元素进行了检测。所有样品中均检出Na、Mg、P、S、K、Ca、Cu、Zn、Se、Sr、Rb、Mo等12种元素。电感耦合等离子体质谱检测到超过一半的样品中含有Al、Cs和Ba3种元素。多元回归分析提取出母亲和婴儿的生物属性，如母亲的身高、母亲的体重或婴儿的出生体重，这些都是导致牛奶中元素浓度变化的统计显著因素。然而，在所有情况下，缴款率都很低。结果表明，母婴的生物学属性不是造成母乳中元素变化的主要因素。
Multielement analysis was performed on human milk collected on 5-9-d postpartum from 51 Japanese females using inductively coupled plasma (ICP) mass spectrometry (MS), ICP atomic emission spectrometry (ICP-AES) and fluorometry. Thirty-one elements were detected by these analytical methods in milk. Twelve elements (Na, Mg, P, S, K, Ca, Cu, Zn, Se, Sr, Rb, and Mo) were detected in all of the samples. Al, Cs, and Ba were the elements detected by ICP-MS in more than half of the samples. Multiple regression analysis extracted biological attributes of mother and infant, such as maternal stature, maternal wt, or infant's birth wt, as statistically significant factors contributing to the variation in elemental concentration in milk. However, the rates of contribution were small in all cases. It was concluded that the biological attributes of mother and infant examined in this study were not the major factors that contribute to elemental variation in human milk.
