摘要
目的调查分析产妇和新生儿血液和毛发中汞的浓度水平及其相关性。方法选择泉州本地户籍产妇和其新生儿为调查对象,采集产妇血、头发及其新生儿脐带血与头发等样品,采用汞分析仪对样品中汞的含量进行检测;同时对产妇进行书面问卷调查。结果产妇血中汞浓度为(2.9±1.7)μg/L,脐带血汞为(3.7±2.8)μg/L,脐带血/母血汞含量比值为1∶1.27,脐带血汞含量明显高于母血(P<0.05);产妇毛发中汞含量为(681.1±531.5)μg/g、新生儿毛发为(556.7±301.9)μg/g。不论脐带血还是毛发中的汞含量,男性新生儿均高于女性。母血汞和脐带血汞含量超标案例分别占所调查样本的20.8%和14.6%。结论虽然大部分产妇和新生儿处于汞暴露的相对安全水平,但仍有部分产妇和新生儿有汞暴露的潜在风险。
Objective Clinical investigation on the level of mercury in the blood and hair of maternity and newborn,as well as their correlation in the coastal city.Methods Experiment was performed for pregnant women who gave birth between Apirl,2011 and July,2011 in Quanzhou Maternal and Children Hospital,the tested samples included blood,hair as well as umbilical cord blood of maternities and their newborns.RA-915＋ mercury analyzer was employed to determinate the mercury concentrations in different samples based on zeeman atomic absorption spectrometry.Results The experimental results showed that the mean concentration of mercury in the blood of maternity was（2.9±1.7）μg/L,while the mean concentration of mercury in umbilical cord blood was（3.7±2.8）μg/L,which was 1.27 times higher than that of maternity.The mean concentration of mercury in the hair of maternity was（681.1±531.5）μg/g,while the mean concentration of mercury in the hair of newborn was（556.7±301.9）μg/g.Not only in the umbilical cord blood,but also in hair,the concentrations of mercury in the male newborn were higher than that of female.The percentage of blood samples from maternity and newborn whose Hg content exceeded the standard established by USA to the total samples were 20.8% and 14.6%,respectively.Conclusion A amount of pregnant women and their newborn suffered from health risk of Hg exposure despite most of investigated samples in this region had no exposure risk.
