产妇血、乳汁和尿中铅、镉含量水平60例分析

Analysis on the lever of lead and cadmium in blood,urine and milk of 60 cases mothers after labor

【目的】研究母亲体内铅、镉含量以及与母乳、母尿之间关系,指导孕期保健和母乳喂养。【方法】应用石墨炉原子吸收仪测定60例产妇血、乳汁和尿中铅与镉含量。【结果】60例产妇血铅含量平均水平0.497μmol/L,46.6%的产妇血铅高于0.483μmol/L,产妇血铅与母乳铅含量差异有显著性(P<0.05)。产妇血铅水平在0.483μmol/L左右时,母乳中铅含量较低。母血中镉含量与母乳中含量基本相同,两者差异无显著性(P>0.05)。【结论】应积极开展孕妇血铅水平的监测及预防;母乳中铅含量对婴儿的影响较小,母乳喂养对于婴儿是安全的。

[Objective] To study the relationship between lead and cadmium in blood with lead and cadmium in milk for guidance maternal breast-fed. [Method] Plumbago furnace atomic absorption was used to determine the lever of lead and cadmium in 60 cases parturient＇s blood, urine and milk. [ Results] The average lever of maternal blood lead was 0. 497 umol/L,46.6% maternal blood lead levers were more than 0. 483 umol/L. There was manifest difference between maternal blood lead and milk lead levers （P〈0.05）. The milk lead lever was lower when maternal blood lead lever was 0. 483 umol/L. The lever of cadmium in maternal blood and milk was same. [Conclusion] Monitoring of serum lead level should be vigorously carried out. Breast milk is safety for baby.
