Abstract
The tissue distribution of lead (Pb) was examined in the neonatal rat intragastricaliy administered lead acetate (50 mg/kg, containing 210 Pb) beginning on d 6 postpartum and thereafter at 3‐d intervals to d 18. A time‐dependent pattern of uptake was observed in bone, kidney, liver, and brain, while stomach, lung, heart, and spleen had no accumulation of Pb. The highest concentration of Pb at d 21 was detected in bone, and the least amount was found in blood and brain. Body weight was not significantly affected by the level of Pb exposure employed.
