目的:了解丽水地区妊娠妇女血铅水平及其变化。方法:2009年-2011年就诊我院妊娠妇女726例,年龄在22岁～40岁,静脉采血,使用博辉BH2100型原子吸收光谱仪,测定其血铅水平。结果:血铅含量平均值及各组中位数分别为:对照组34.55±18.99μg/L,33.22μg/L;早妊组32.43±19.46μg/L,30.5μg/L;中妊组29.05±17.47μg/L,25.5;晚妊组29.52±18.09μg/L,28.11μg/L。妊娠期妇女血铅水平低均于未妊娠健康妇女,除了早妊组(P>0.1),其余各组差异均具有显著性(P<0.05);年龄大于35岁的高龄孕妇与适龄孕妇血铅水平无显著差异(P>0.1)。结论:妊娠期妇女血铅水平呈下降趋势,如果妊娠期血铅水平有上升趋势,应警惕铅暴露对孕妇及胎儿的危害。
Objective: To understand the level of blood lead and its changes in pregnant women in Lishui area. Methods: From 2009 to 2011, 726 pregnant women in our hospital were treated with venous blood collected from 22 to 40 years old. The blood lead levels were determined using Bohui BH2100 atomic absorption spectrometer. Results: The average level of blood lead and the median of each group were 34.55 ± 18.99μg / L and 33.22μg / L respectively in the control group, 32.43 ± 19.46μg / L and 30.5μg / L in the early pregnancy group and 29.05 ± 17.47μg / L, 25.5; late pregnancy group 29.52 ± 18.09μg / L, 28.11μg / L. The level of blood lead in pregnant women was lower than that in healthy women without pregnancy, except for the early pregnancy group (P> 0.1), the differences among the other groups were significant (P <0.05). The blood lead levels in older pregnant women older than 35 years There was no significant difference (P> 0.1). Conclusion: The blood lead level of pregnant women shows a declining trend. If the level of blood lead during pregnancy is on the rise, the hazard of lead exposure to pregnant women and fetuses should be alert.
