Abstract:
Lead concentrations in household drinking water were matched with blood lead levels in 46 women of childbearing age (37 of whom were pregnant) who reside within the city of Milwaukee. The women represented a geographically diverse sample. Water lead concentrations ranged from less than 10 micrograms/L (65% of all homes studied) to 160 micrograms/L. None o the women tested had blood lead levels within the range most recently designated by the Centers for Disease Control (CDC) as "at risk" for the developing fetus (greater than or equal to 10 micrograms/dL). Within the limits of this study, there was no biologically significant correlation between blood lead and drinking water lead levels, suggesting that household water in Milwaukee with first-draw lead concentrations above EPA standards, either proposed or current, may have little or no biological effect.
