Lead levels in samples of the groups at highest risk to the effects of lead exposure, pregnant women and their infants, are higher than levels known to produce developmental retardation in children in a considerable proportion of the sample tested in Mexico City. Modeling of prenatal factors predicting maternal lead during pregnancy shows the strong effect of the use of low-temperature ceramics on lead level. The data also suggests an important contribution from air lead. The downward trend in lead exposure in pregnant women in the Valley of Mexico over the last 10 years, concurrent with downward trends in air lead is encouraging. However, reducing the manufacture and use of leaded pottery could produce a significant further reduction of lead exposure with a modest program of public education, government regulation and subsidization of lead free pottery.
在铅暴露影响风险最高的群体样本中，即孕妇及其婴儿，墨西哥城相当一部分受测样本中的铅含量高于已知会导致儿童发育迟缓的水平。预测孕期母体铅含量的产前因素模型显示，使用低温陶瓷对铅含量有强烈影响。数据还表明空气中的铅有重要影响。墨西哥谷孕妇铅暴露在过去10年呈下降趋势，与空气中铅含量的下降趋势一致，这令人鼓舞。然而，通过适度的公共教育、政府监管和无铅陶器补贴计划，减少含铅陶器的制造和使用，可能会进一步大幅降低铅暴露。
