Pharmacokinetic model to describe the disposition of lead in the rat.

A pharmacokinetic model was developed to describe the disposition of lead in the rat. The model can be used to predict the effect of acute high-dose as well as low-dose exposure to lead. These results suggest that the model should be able to predict the effect of chronic low-dose exposures as well. Plasma, bone, liver, and bile profiles were generated from this model using previously published data. The results obtained supported the existing theory that lead demonstrates a dose-dependent pharmacokinetic profile in the rat.
