It is obvious that lead intake is of concern not for its beneficial/essential effects on metabolism, but rather for its toxic actions, which can be especially damaging to children. The objective of this study was to analyze the concentration of lead in milk of mothers during prolonged lactation. Milk samples from 43 mothers were collected at 2 months postpartum. Lead was analyzed using atomic absorption spectrophotometer. The value of lead in human milk was 23.66±22.43 μg/l. Lead concentration in human milk of mothers was higher than other countries and no significant relationship was found between levels of human milk lead and mother's education, age, parity, height and weight. The concentrations of lead in the milk samples were high, which makes a major public health hazard for the inhabitants, especially neonatal and children, of the industrial locations.
显然,铅摄入令人担忧的并非其对新陈代谢的有益/必需作用,而是其毒性作用,这对儿童尤其具有损害性。本研究的目的是分析长期哺乳期母亲乳汁中的铅浓度。在产后2个月收集了43位母亲的乳汁样本。使用原子吸收分光光度计分析铅含量。人乳中铅含量为23.66±22.43μg/l。母亲人乳中的铅浓度高于其他国家,且人乳铅水平与母亲的教育程度、年龄、产次、身高和体重之间未发现显著关系。乳汁样本中的铅浓度很高,这对工业区的居民,尤其是新生儿和儿童构成了重大的公共卫生危害。
