The study was designed to measure the gradients of lead, iron, copper and zinc from maternal blood to cord blood in pregnant urban and rural women. The concentrations of iron, copper, zinc and lead were measured by means of atomic absorption spectometry (AAS) in whole blood of 100 normal parturients and 92 of their neonates. Levels of lead in cord blood were not significantly different from those in maternal blood. This ratio was associated with similar iron and zinc ratios. Neonatal birth weight was negatively correlated with maternal copper levels, whereas cord blood zinc values positively correlated with placental weight. Rural women showed higher maternal to cord blood lead ratios than urban women. The implications of these findings are discussed.
该研究旨在测量城市和农村孕妇从母血到脐血中铅、铁、铜和锌的梯度。通过原子吸收光谱法（AAS）测定了100名正常产妇及其92名新生儿全血中铁、铜、锌和铅的浓度。脐血中的铅水平与母血中的铅水平无显著差异。该比例与铁和锌的比例相似。新生儿出生体重与母体铜水平呈负相关，而脐血锌值与胎盘重量呈正相关。农村妇女的母血与脐血铅比例高于城市妇女。讨论了这些发现的意义。
