Lead in human blood and milk from nursing women living near a smelter in Mexico City.
Lead levels in breast milk and blood were determined in women living within a 200-m radius of 3 smelters in Mexico City.
All samples were analyzed on a Perkin Elmer 460 atomic absorption spectrometer equipped with HGA 2200.
The mean blood lead level was 45.88 mug/dl (SD 19.88 mug/dl), and the geometric mean of milk lead level was 2.47 mug/100 ml.
The correlation coefficient of these two variables was 0.88.
Using the mean value of lead found in breast milk, an infant of 5.5 kg would ingest 8.1 mug/kg/d in his diet.
