Abstract

Copper, iron, manganese and zinc were measured in breast milk samples collected from 82 healthy lactating mothers. Samples were collected from day of delivery to 7 days postpartum. Zn was analysed by flame atomic absorption spectrometry and the other elements by electrothermal atomic absorption spectrometry. Copper concentrations remained constant. Iron declined from 14.2 +/- 7.3 mumol/l at day 1 to 5.6 +/- 3.1 mumol/l at day 5 postpartum. Zinc and manganese declined from a maximum at 2 days postpartum (Zn: 183 +/- 70 mumol/l; Mn: 218 +/- 102 nmol/l) to 77 +/- 22 mumol/l (Zn) and 62 +/- 29 nmol/l (Mn) at 6 days postpartum. Copper concentrations are related to parity (r = 0.317, P < 0.001) and mother body mass index (r = 0.324, P < 0.001).

摘要

对82名健康哺乳期母亲采集的母乳样本中的铜、铁、锰和锌进行了测定。样本采集时间为分娩当天至产后7天。锌采用火焰原子吸收光谱法分析，其他元素采用电热原子吸收光谱法分析。铜浓度保持恒定。铁从产后第1天的14.2±7.3μmol/l降至产后第5天的5.6±3.1μmol/l。锌和锰从产后第2天的最高值（锌：183±70μmol/l；锰：218±102nmol/l）降至产后第6天的77±22μmol/l（锌）和62±29nmol/l（锰）。铜浓度与产次相关（r = 0.317，P < 0.001），与母亲体重指数相关（r = 0.324，P < 0.001）。
