Dong Soo Lee, Jun Sakong, Seok Beom Kim, Chang Yoon Kim, Pock Soo Kang, Jong Hak Chung
To investigate the blood lead concentration, their interrelation, correlation factor and influence on pregnant women and newborn, lead concentration in the maternal blood and umbilical cord blood were determined. Samples were collected from 130 mothers who were living in the Taegu City, during March, 1989. Blood lead concentration was estimated using the Atomic Absorption Spectrophotometer (IL. 551) equipped with Flameless Furnace Atomizer (IL. 665). The mean lead concentration of maternal and cord blood were 17.47±7.92 µg/dl, 15.31±7.98 µg/dl, respectively. A significant correlation was observed between the lead concentration of maternal and cord blood, r=0.663, Y=0.667X+3.646. No significant correlation was observed between previous spontaneous abortion and obstetric complication of mother and maternal blood lead concentration. Similarly, no significant correlation was observed between the sex, gestational age of neonate and cord blood lead concentration. But the birth weight of neonate had some negative correlation with cord blood lead concentration. The blood lead concentration of mother who had engaged in manufactures were higher than others and the longer working years were, the higher blood lead concentration were. Significant correlation was observed between husband's occupational exposure to lead and maternal blood lead concentration.
