Abstract

This study was conducted to evaluate the blood lead levels in 141 pregnant women who were not occupationally exposed to lead and their umbilical cord, arid to identify some differences in blood lead levels by living area. The subjects-were all delivered at St. Benedict Hospital in Pusan and the blood lead levels were measured by graphite furance atomic absorption spectrophotometer.
The summarized results were as follows.
1. The geometric mean lead levels in maternal and cord blood were 8.0+/-1.8microgram/dl, 5.0+/-0.6lmicrogram/dl respectively.
2. Lead levels in maternal (8.7+/-1.7microgram/dl) and cord blood(5.4+/-0.7microgram/dl) of industrial area(n=24) were higher than residential area(n= 124) which were 7.9+/-1.7microgram/dl and 5.0+/-0.6microgram/dl respectively (p<0.05).
3. Maternal blood lead concentration was significantly correlated to cord blood lead concentration (r=0.6090, p<0.001), but other variables (maternal age, paternal smoking, birth weight, etc) were not correlated.
