目的铅能通过胎盘,当母亲血铅水平大于50μg/L时,就已经对胎儿产生了影响。笔者通过随机对西安市2010年10～12月份怀孕1～8个月的孕妇静脉血血铅含量的测定。提高人们对低浓度血铅对孕妇造成的危害引起高度重视。方法北京博晖创新光电技术有限公司生产的专门用于临床检测血铅的BH2100原子吸收分光光度仪。结果 1286例孕妇静脉血中大于50μg/L小于100μg/L是98例占7.62%;大于100μg/L小于200μg/L的是2例占0.15%,无轻度、中度、重度铅中毒。结论胎盘对血铅无屏障作用,虽然孕妇血铅的正常值是0-100μg/L,但是有资料表明超过50μg/L,就会对胎儿造成危害。1286例孕妇中血铅值大于50μg/L的占到了7.78%,要足够引起人们的重视。
The purpose of lead through the placenta, when the mother’s blood lead levels greater than 50μg / L, it has had an impact on the fetus. The author through a random analysis of Xi’an City in 2010 10 ~ December pregnant 1 to 8 months pregnant women blood lead content determination. Raising people’s attention to the harm caused by low concentration of blood lead to pregnant women. Methods Beijing Bo Hui Innovative Optoelectronics Technology Co., Ltd. produced specifically for the clinical detection of blood lead BH2100 atomic absorption spectrophotometer. Results In 1286 pregnant women with venous blood more than 50μg / L and less than 100μg / L, 98 cases accounted for 7.62%. More than 100μg / L and less than 200μg / L were two cases, accounting for 0.15%. No mild, moderate or severe lead poisoning was found. Conclusion The placenta has no barrier effect on blood lead. Although the normal value of blood lead in pregnant women is 0-100μg / L, there are data that more than 50μg / L, it will cause harm to the fetus. 1286 cases of pregnant women in the blood lead value greater than 50μg / L accounted for 7.78%, enough to cause people’s attention.
