The chromium concentration was determined in 261 samples of breast milk collected by manual expression from forty-five American women. Cr was measured in whole, liquid milk by graphite-furnace atomic absorption spectrophotometry, using the method of standard additions. The mean Cr content of the breast milk samples was 0.30 ng/ml. The range of individual values was 0.06-1.56 ng/ml and did not change significantly with duration of lactation. The Cr content of breast milk from these American women is similar to levels reported recently in milk from Finnish women.
通过人工挤奶收集了45名美国女性的261份母乳样本，并测定了其中的铬浓度。采用标准加入法，通过石墨炉原子吸收分光光度法对全脂液态母乳中的铬进行了测定。母乳样本中的铬平均含量为0.30纳克/毫升。个体值范围为0.06 - 1.56纳克/毫升，且不随哺乳期的延长而显著变化。这些美国女性母乳中的铬含量与最近报道的芬兰女性母乳中的含量相似。
