The breast milk of 86 economically poor Indian women was analysed by neutron activation analyses for Mo, As, Mn, Zn, and Cu concentrations. The colostrum of 10 tribal women contained 0.27 microgram Cu/g, 2.1 micrograms Zn/g, 19.9 ng Mn/g, 0.73 ng As/g and 5.4 ng Mo/g, whereas 19 urban women had corresponding concentrations of 0.91 microgram Cu/g, 7.3 micrograms Zn/g, 15.3 ng Mn/g, 0.5 ng As/g and 15.3 ng Mo/g. A survey of mature milk between 1 and 6 months, 6 and 12 months and 1 and 2.5 years indicated decreasing concentrations of Zn and Mo, but increasing Mn concentrations as the post-partum period progressed. Malnourished infants received breast milk containing less Cu, Zn and Mn than those who were better nourished and of the same age group. The results, therefore, imply the necessity of supplementing breast feeds in the economically poorer groups.
通过中子活化分析，对86名印度贫困妇女的母乳进行了钼、砷、锰、锌和铜浓度的分析。10名部落妇女的初乳中，铜含量为0.27微克/克，锌含量为2.1微克/克，锰含量为19.9纳克/克，砷含量为0.73纳克/克，钼含量为5.4纳克/克；而19名城市妇女初乳中相应元素的含量分别为：铜0.91微克/克，锌7.3微克/克，锰15.3纳克/克，砷0.5纳克/克，钼15.3纳克/克。一项针对产后1至6个月、6至12个月以及1至2.5年的成熟母乳的调查表明，随着产后时间的推移，锌和钼的浓度降低，但锰的浓度升高。营养不良婴儿所摄入母乳中的铜、锌和锰含量低于营养状况较好的同龄婴儿。因此，研究结果表明经济较贫困群体有必要对母乳喂养进行补充。
