摘要
对湖北地区非职业铅接触的 90名孕妇和新生儿血铅及生长发育情况进行了追踪调查。结果显示 :孕 2 8周内血铅水平为 0 2 90 μmol/L ,分娩前为 0 32 6 μmol/L ,孕期血铅水平呈增高趋势。新生儿脐血血铅含量为 0 333μmol/L ,其中 17 8%的新生儿脐血血铅含量高于 0 483μmol/L。逐步回归分析显示新生儿脐血血铅含量 (Y3)与孕 2 8周内血铅 (Y1)及分娩前血铅 (Y2 )均有高度线性关系 :Y3 =0 12 2 5 10 6 7+0 16 0 945 91Y1+ 0 780 7786 5Y2。Y3与Y2之间的直线相关系数r=0 6 80 5 ,P <0 0 1。
To study pregnant women exposure to lead and its effect on fetus in Hubei,we selected 90 pregnant women from three un-similar districts,who had no know occupational exposure to heavy metals.Under strict quality control,the blood was obtained.The blood level was determined with Japan 180-80 flame atomic absorption spectrometer.The results showed:the geometric mean(GM)PbB of the 28 weeks of pregnancy(Y1) and delivery(Y2) was 0.290μmol/L and 0 326μmol/L,respectively.The GM PbB level of umbilical cord (Y3) is 0 333μmol/L(17.8%umbilical cord PbB>0.483 μmol/L).The correlation coefficient of Y3 and Y2 was 0.6805,P<0.01.Y3=0.12251067+0.16094591Y1+0.78077865Y2 by stepwise regress.But the lead level didn't cause adverse effects on fetal development.
