Flameless atomic absorption spectrophotometry has been applied to the analysis of manganese in human milk samples. Twenty-seven breast-feeding mothers donated 229 individual milk samples between the 2nd week and the 9th month of lactation. The milk samples were representative of every feed in a period of 24 hours, foremilk and hind-milk in equal proportions. The median concentration of manganese declined from the initial value of 5.9 microgram/l to about 4 microgram/l before the 2nd month of lactation, remained at this level up to the 5th--6th month of lactation and showed a tendency to rise thereafter. The values presented here are noticeably lower than most of those reported earlier. It remains an open question whether the manganese concentration is exceptionally low in Finnish human milk or whether the great difference from most earlier studies may reflect problems of contamination or technical difficulties when less sensitive analytical methods have been used.
无火焰原子吸收分光光度法已应用于母乳样品中锰的分析。27位哺乳期母亲在哺乳第2周和第9个月期间捐赠了229份个体母乳样品。这些母乳样品代表了24小时内每次喂食的情况，前奶和后奶比例相等。锰的中位数浓度从哺乳期第2个月前的初始值5.9微克/升下降到约4微克/升，在哺乳期第5至6个月保持在该水平，此后呈上升趋势。这里给出的值明显低于大多数早期报道的值。芬兰母乳中的锰浓度是否异常低，或者与大多数早期研究的巨大差异是否可能反映了使用不太灵敏的分析方法时的污染问题或技术困难，这仍然是一个悬而未决的问题。
