The purpose of this study was to determine the blood lead levels (Pb-B) of urban pregnant women with low incomes and/or living in areas with heavily traveled roads, dilapidated housing, and industrial plants. We measured blood lead in 1,055 pregnant Minneapolis-area women at entry to prenatal care and in one-third of the sample during the second half of pregnancy. The mean Pb-B level of the first sample (n = 1,055) was 1.83 +/- 1.83 micrograms/dL; of the second sample (n = 375), 1.99 +/- 1.92 micrograms/dL. Only one woman had a Pb-B level greater than 12.0 micrograms/dL, which was the result of occupational exposure. The low lead levels found in this study indicate that it is not necessary to routinely screen pregnant women for elevated Pb-B levels in our geographic area. Rather, women should be screened via an environmental questionnaire to ascertain the risk of lead exposure.
本研究的目的是确定低收入和/或居住在交通繁忙道路、破旧房屋及工厂附近地区的城市孕妇的血铅水平（Pb-B）。我们在明尼阿波利斯地区1055名孕妇首次接受产前护理时测量了她们的血铅水平，并在其中三分之一的样本怀孕后半期再次进行测量。第一个样本（n = 1055）的平均血铅水平为1.83±1.83微克/分升；第二个样本（n = 375）的平均血铅水平为1.99±1.92微克/分升。只有一名女性的血铅水平高于12.0微克/分升，这是职业暴露的结果。本研究中发现的低血铅水平表明，在我们所在的地理区域，没有必要对孕妇进行常规的血铅水平升高筛查。相反，应该通过环境调查问卷对女性进行筛查，以确定铅暴露的风险。
