Concentrations of Lead in Capillary Blood of Newborns

[摘要] Lead concentrations in whole blood have been determined for a random sampling of newborns (age 1-8 days) with the use of a microtechnique involving carbon rod atomization and atomic absorption spectrophotometry. The mean lead concentration of the newborns (13.8 ± 4.5 µg/100 ml of whole blood) significantly differed from that of pediatric populations at low (22.6 ± 6.1) and high lead (32.1 ± 10.4) risk. The concentration of lead in amniotic fluid was less than 20 ng/100 ml of fluid. The significance of the newborn lead values and their role in fetal development remains to be determined.
