Using low temperature ashing and graphite furnace atomic absorption, the concentration of chromium in breast milk samples of 10 breast-feeding mothers was measured and the chromium intake of their totally breast-fed infants was evaluated. Ten samples were collected during 8 to 18 days and five samples during 47 to 54 days and 128 to 159 days of lactation. The milk samples represented every feed during a period of 24 hr and contained foremilk and hindmilk in equal proportions. The mean chromium concentration in the breast milk was 0.39 (SD 0.15) ng/ml and the intake 0.27 (SD 0.11) microgram/day. The mean chromium concentration, or intake in the breast milk did not significantly change with advancing stages of lactation.
采用低温灰化和石墨炉原子吸收法，对10名哺乳期母亲的母乳样本中的铬浓度进行了测量，并评估了其纯母乳喂养婴儿的铬摄入量。在哺乳期的第8至18天收集了10个样本，在第47至54天以及第128至159天收集了5个样本。母乳样本代表了24小时内的每次喂奶，且前奶和后奶比例相等。母乳中的平均铬浓度为0.39（标准差0.15）纳克/毫升，摄入量为0.27（标准差0.11）微克/天。母乳中的平均铬浓度或摄入量并未随着哺乳期的推进而发生显著变化。
